Signs of a Blown Head Gasket

#driveyourlife

One of the best ways to figure out what is going on with your car is to know how it normally operates so you can tell when something has gone awry.  Most of the time while we’re driving we’re so distracted by the radio, the scenery or even worse our cell phones, that we can often overlook our vehicle’s cry for help.  Getting used to the way your car sounds, feels and looks normally can be the best way to help you detect the early symptoms of a problem so you can repair it before it leaves you stranded or does even more damage to your vehicle.

Every week or so, it would be a good idea to turn off your radio and really focus on the feedback your car is giving you.  You should start this exercise from the moment you jump in your vehicle, even before you start the engine.  Look for anything unusual around or under your car.  Are there any puddles or drips under your vehicle?  Are there any new scratches, dings or dents you don’t remember?  Is anything discolored, are your tires pudgy or getting cracked or have low tread depth?  Observing all these things can help you catch problems early.

Also, pay attention to when you start your engine.  Does it start easily?  Does it make any funny noises or smells?  Do any warning lights on your dash board stay on after the engine is running?  Lastly, during your drive listen for the same types of things.  Are there any clunks, rattles, whines, or grinding sounds?  If so when do they happen?  Does your car accelerate, brake and corner smoothly?  Keeping an eye on these types of things can help you make sure your car is in great shape and help you catch a warning sign early.

Some of the signs you may be looking for, especially if your car model is prone to blown head gaskets, or you happen to have a lot of miles on your car, are the sings of a blown head gasket.  Blown Head Gaskets can cause your vehicle to do some very strange things and give confusing symptoms, so we’ll list the common blown head gasket symptoms here so you can identify your problem early.

Signs of a Blown Head Gasket:

  • White smoke from the tail pipe
  • Bubbles or exhaust gas in your radiator
  • Coolant flowing out of your coolant reservoir
  • White milky substance in your engine oil or around your oil cap
  • Loss of power
  • Overheating engine
  • Coolant leak from between your engine block and cylinder head

Your head gasket serves as a seal between your engine block and cylinder head.  It keeps the combustion gases in the combustion chamber while keeping the coolant in the water jacket.  A blown head gasket will allow coolant to leak into the combustion chamber, or externally, or could allow combustion gases into the cooling passages.

If coolant leaks into the combustion chamber it will come out of your tail pipe as white smoke.  It can also seep past your piston rings while your engine is off and contaminate your oil causing a milky white color.  When your engine is running, the high pressures in your combustion chamber can push exhaust gases into the cooling passages causing coolant to bubble in the radiator and pressures to get so high that coolant will actually be forced out of the coolant reservoir.

If you are experiencing any of these symptoms within a few minutes of starting your vehicle’s engine, there is a good chance you have a blown head gasket.

The good news is if you’re paying attention to these symptoms and catch them early, you often can seal your head gasket leak without having to replace the head gasket.  BlueDevil Head Gasket Sealer is a powerful formula that can seal head gasket leaks even in vehicles with very large cooling capacities like V8 engines and truck engines.  BlueDevil Head Gasket Sealer is easy to use and can quickly and easily seal your head gasket leak.

Here are some other questions you might consider:

What Can Happen if You Have a Blown Head Gasket?

Once you’ve discovered that you have a blown head gasket, it’s important to know what might happen next.  Once there is coolant traveling into the combustion chamber it’s important to realize that your coolant level will be slowly lowering.  Once your coolant level gets too low your engine will start to overheat which can lead to significant problems.  Overheating can lead to further deformation of your cylinder head or engine block as well as other leaks in your engine from excessive expansion and contraction of components.  These factors make it important to repair a blown head gasket sooner rather than later to avoid other problems with your vehicle.

How Do You Know if You Have a Bad Head Gasket?

It’s difficult to “know” if you have a blown head gasket without taking your engine apart and inspecting the head gasket for holes or tears.  The most definitive test is a chemical test that checks for the presence of exhaust gases in your coolant that is available at your local auto parts store.  Unfortunately, this test can only prove the presence an internal head gasket leak not an external head gasket leak.  The easiest way to be sure you have a head gasket leak is to look for multiple signs mentioned above.

Can You Drive a Car with a Blown Head Gasket?

Driving with a blown head gasket is a risky operation.  If you’ve got multiple signs of a blown head gasket, you can run the risk of overheating your engine due to a low coolant level as mentioned above.  Similarly, driving with coolant flowing into your combustion chamber will eventually allow coolant into your engine oil.  Water in your engine oil can quickly cause damage to other parts of your engine by allowing the machined and polished surfaces to rust which will cause pitting and excessive wear.  Driving with a blown head gasket can quickly take your repair form a head gasket replacement to an engine replacement.

How Much does it Cost to replace a Blown Head Gasket?

Blown head gasket replacement costs can vary significantly from shop to shop and from vehicle to vehicle so the best way to make sure you’re getting a good deal is to call a few local shops asking for a quote for a head gasket replacement for your vehicle.  You can also check out our article on head gasket repair costs to get an better idea of what labor times look like to replace a head gasket in your car.  The majority of the cost in any head gasket repair job is the labor costs.  Labor costs can vary significantly based on the configuration of your engine and how it is mounted in your vehicle so checking with local mechanics is the best way to estimate cost.  If the cost of replacing your head gasket is prohibitive based on your budget or the value of your vehicle, consider using BlueDevil Head Gasket Sealer to save money and keep your vehicle on the road!

          Nichole-

          Thank you for asking about your Dodge Durango. From the sounds of it, you have both a coolant and fuel leak. Unfortunately, we do not manufacture a product intended to stop fuel leaks. Addressing your fuel leak should be your first priority, as it is not safe to drive a vehicle leaking fuel. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          Thank you!

            I have a 2000 Dodge Durango. I drove back home on leave the vehicle made almost the 11 hour drive With no issues. The engine was not over heating and then out of nowhere my oil pressure dropped and the vehicle stalls in idle and will not crank unless it’s jumped. The oil was changed a day prior to the trip.



          • BlueDevil Pro on December 28, 2020 at 9:31 am

            Izaak-

            Thank you for asking about your Dodge Durango. A drop in the oil pressure wouldn’t necessarily indicate a head gasket failure. Were you having any issues prior to making the drive? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

            Thank you!

        I also have an Eldorado. My ECT switch is broken, or faulty. Either way, they’re ran to the motor manually to fur the cooling fans on. I have used Bar’s stop leak powered because a street mechanic “informed” me that my (2nd?) heater hose just beneath the initial one, may have had a hole in it. It didn’t. He then tells me what the hose was anchored to has a hole rusted through it. But my initial thoughts on this car was I might need a rebuild soon. He gets all the symptoms Miguel’s mention for his car. He takes 30 min to an hour to get hot if fans are connected. Otherwise, I’m riding in the middle. There’s no water or coolant in the oil. I find myself needing a jump three times a day, everyday for the past 2 weeks .

        • BlueDevil Pro on August 21, 2017 at 9:58 am

          Harlem-

          Thank you for asking about your Cadillac Eldorado. In order to get the benefit of using the BlueDevil Head Gasket Sealer, the vehicle would need to be able to idle for a full 50 minutes, without overheating or stalling out, and you shouldn’t be losing more than about a quart of water/coolant during that 50 minutes. Based on your description, unfortunately, the vehicle may be overheating a little too quickly for the product to be effective. A hard part repair may be your best option.

        My ML320 list steering – had it towed into mechanics. Replaced serpentine belt & something with water pump. Several days later – no coolant in reservoir. Took it in again. Mechanic said they had crimped hose leading from reservoir & fixed it. Now I’m seeing oil & ?coolant marks on pavement. Was my engine possibly damaged from no or low coolant?

        • BlueDevil Pro on December 6, 2021 at 8:49 am

            Thank you for asking about your Volvo S40. Based on your description, the leak you have may be a little larger than what BlueDevil would be able to seal. In order to get the benefit of using the product, the vehicle would need to be able to maintain idle for a full 50 minutes without overheating or stalling out, and you shouldn’t be losing more than about a quart of water/coolant during that 50-minute run. If you are losing coolant just as quickly as you add it, a hard part repair may be your best option.

          1991 Honda prelude…temp gauge rises up and down…no white smoke but does use antifreeze….can it be thermostat…water pump or head gasket?reach me at moorefamilytrucking@gmail.com

          • BlueDevil Pro on January 25, 2021 at 9:37 am

            Tye-

            Thank you for asking about your Honda Prelude. The most common reason the temperature gauge is fluctuating would be due to a faulty thermostat. The thermostat may be sticking and not opening up when it is supposed to, causing the temperature to rise and thusly fall when the thermostat opens up. Replacing the thermostat would be a good place to start.

            Thank you!

      Hi there why does my water bubble when I stop my van like it’s blowing out air on my Vauxhall combi van 2003 turb why does my water bubble when I stop my van I have no water in my oil and I have no heating but my van don’t overheat

      • BlueDevil Pro on June 12, 2017 at 10:45 am

        Tyrone-

        Thank you for asking about your Vauxhall Combi Van. It is possible that you are getting combustion/exhaust gases pumping back into the cooling system.  You can use a “Block Dye Tester” to confirm whether or not that is the case.
        BlueDevil Head Gasket Sealer will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure.  To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading.  If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.  Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.  Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

        Thank you!

          My van overheated and died out. Checked under hood and one of the hoses came off. Reconnected it tried to start it and no start battery died out. Got it jumped and car started but Idle was rough. So drove it a mile checked how it ran and it was fine till I stopped and sat for 2 min and engine died. Tried jump again but didn’t start anymore. What can I check or do to figure out why it doesn’t start anymore?

            Antonio-

            Based on your description, we’d recommend checking the spark plugs to make sure they are not deteriorated or fouled out. The rough idle you were experiencing could be due to water/coolant getting back into the cylinders and fouling out the plugs. Feel free to contact our technical support line at 888-863-0426 with any other questions.

    Hi,

    I have a 1991 Toyota Corolla that I have just done a complete engine over hall on it a few weeks ago. Last week, my car cut off on me and wouldn’t start again. upon checking the car after having it towed home, I noticed that the water in the radiator and over flow bottle bubbles when the car is idling and there is a film of white (milky looking substance) under the oil cap. Please tell me what the problem could be and if you have a product that is guaranteed to repair the problem?
    Does your product come with a money back guarantee and where can I purchase the product as I am based in Durban, South Africa.

    Thank You.

    • BlueDevil Pro on October 24, 2015 at 11:02 am

      Mahesh,

      Thanks for your question about your 1991 Toyota Corolla. It sounds like you’ve got a blown head gasket which definitely shouldn’t happen on a recently overhauled engine. Before using our products, we would recommend taking your car back to the shop that did the work on your vehicle and seeing if they will install a new head gasket under warranty as it could very well have been from improper installation. If that doesn’t work, you can use BlueDevil Pour-N-Go (http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) to seal your leak. Please contact our sales department for international shipping options.

      Thanks again for your question!

        There are so many different possibilities as to why your Malibu shut off while driving. We recommend having a certified mechanic take a look at it for a proper diagnosis. Once you have the diagnosis you will have a much better idea as to what your options are for getting it fixed.

    My 2008 Nissan Rogue just started rattling today. It’s not over heating or anything else. Just rattling. Do you know what this could be?

    • BlueDevil Pro on October 31, 2015 at 11:34 am

      Wendy,

      Thanks for your question about your Nissan Rogue. It depends on where you’re hearing the rattle from. If the rattle is something you hear when you’re going over bumps it could be a loose suspension component. If that is the case, try reading our article about noise suspension components here: https://gobdp.com/blog/squeaky-suspension/.

      If the rattling you’re hearing is coming from your engine then it sounds like you’ve got a pulley or accessory read to fail. Since you mentioned overheating it could be that the bearings in your water pump are going bad, but it could be the idler pulley or another accessory. Try checking under your hood while your car is idling and seeing you any of the pulleys look loose or wobble. Which ever on looks bad probably needs to be replaced.

      Thanks again for your question!

    Hi,

    I have a 2004 Dodge Ram 1500 V8, 4.7 L truck.
    Sometime ago, my truck’s engine overheated during a ride through a mountain. I stopped, let it cool, checked the coolant and continue the trip.

    After a while, maybe a month, while going to work, I noticed it suddenly overheated again, even though I regularly check the oils and coolant. This time the engine died and I was able to stop in a parking lot. I noticed the coolant had leaked and when engine cooled I opened the radiator valve and it had oil residue in it. i was able to start the truck for a little while just enough to properly park it. The engine did not start again after that and I had it towed. The electric system was fine.

    Here’s my question: Does your product work also in my case? I read the instructions for your product and it says that after cleaning the system I have to start the engine and let run for sometime while pouring the product, etc. etc.

    So, can your product help to save my truck’s engine? Thanks

    Ernesto

    • BlueDevil Pro on November 20, 2015 at 5:11 pm

      Ernesto,

      Thanks for your question about your Dodge Ram. It does sound like you’ve got a blown head gasket based on the symptoms. You can try and confirm that by doing a compression check on each cylinder and seeing if one is lower than the others. The low cylinder would be the one with the hole in the head gasket. If that is the case you can try starting your truck with the spark plug removed from that cylinder, which may help get your truck to idle. You need your truck to be able to idle for at least 50 minutes without overheating to use BlueDevil Head Gasket Sealer.

      Thanks again for your question!

      Today I drove my car when I made it to my destination a lot of liquid came rushing from underneath the car then as I drove the car overheated then shut off and the oil leaking light came on plz help. Thanks

      • BlueDevil Pro on August 8, 2019 at 8:26 am

        Tina-

        Was the liquid rushing from underneath coolant or oil? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

    I have a 95 maxima and mi antifreeze was leaking thru mi head gasket and I check to c wea it cums from and it was in mixed with engine oil and den I changed the oil is there anyway to fix it

    • BlueDevil Pro on November 16, 2015 at 11:11 am

      Shaquan-

      Based on your description, we would recommend using the BlueDevil Head Gasket Sealer. You are going to want to change the oil before and after the BlueDevil process. As long as the vehicle can idle for a 50 minutes without overheating or stalling out, and you’re not losing more than about a quart of coolant/ water during that 50 minutes, the product should be able to help seal your leak.

      Thank you!

        Why do you have to change the oil before and after?

        • BlueDevil Pro on August 8, 2016 at 4:12 pm

          Ron-

          This direction only pertains to users who are getting water/coolant into their oil. You really don’t want to operate the vehicle with water in the oil. If the water started to deteriorate the engine bearings, it would cause further engine damage, and it is likely you would need to replace the engine. Also, the product does not instantaneously seal, so you would still get a little water/coolant in the oil during the 50 minute idle, prompting the second oil change, once the BlueDevil process is complete. Feel free to contact our technical support line at 888-863-0426 with any other questions.

          Thank you!

        does it have to idle or can it be driven for that long?

        • BlueDevil Pro on April 12, 2017 at 9:04 am

          Big Boy-

          The vehicle should only be idling during the 50 minute run. You would not want to put extra compression in the system.

      • BlueDevil Pro on January 4, 2017 at 9:08 am

        Rob-

        Thank you for asking about your Jeep Cherokee. Based on your description, it seems like you may be losing coolant a little too quickly for the BlueDevil Head Gasket Sealer to be effective. In order to get the benefit of using the product, the vehicle would need to maintain idle for a full 50 minutes without overheating or stalling out, and you shouldn’t be losing more than about a quart of water/coolant during that 50 minutes. A hard part repair may be your best option.

        Thank you!

    Hi I have a bmw 325i e36 and it just started overheating. I don’t have any white smoke out the tail pipe but my coolant bubbles through my expansion tank. She does not give me a rough ride but I would like to know if this is a symptom of a blown head gasket or something else?

    • BlueDevil Pro on December 23, 2015 at 4:15 pm

      Alex,

      Thanks for your question about your BMW 325i. It is a possibly the overheating and bubbles are simply an indication of low coolant level in your car so make sure you’re engine is full of coolant and all the air bubbles have been removed from your system. Try checking for some of the other symptoms like milky oil around the oil cap. To be sure you can try doing a compression check which should be relatively easy to do on your car. If 1 or 2 cylinders have low compression, combined with the overheating and bubbles it would indicate a blown head gasket.

      Thanks again for your question!

    I have a 2003 Chevy Cavalier. It loses coolant very rapidly, and what comes out of the exhaust pipe is largely white steam. But I don’t see any other obvious symptoms, such as coolant in the oil or vice-versa. Is it more likely a cracked block or blown head gasket? If I decide to try both Radiator and Block Sealer and Head Gasket Sealer, which is it better to try first? I am guessing that the deposits left by one product may interfere with the working of the other later on, but I don’t know that for a fact. Thanks for any suggestions.

    • BlueDevil Pro on January 7, 2016 at 6:26 pm

      Joe,

      Thanks for your question about your 2003 Cavalier. The problem you’re describing does sound like a blown head gasket rather than a cracked block. If you had a cracked block you would have an external leak or be seeing a lot of water in your oil. We would recommend trying BlueDevil Pour-N-Go Head Gasket Sealer (available here: http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) first as that should solve all your problems.

      Thanks again for your question!

    I have a 2005 Buick lacrosse .. I had my thermostat changed several times and buying antifreeze… Because my car would run hot but when I get on gas it will cool down.. Month or two later it started back .. Bought another thermostat and antifreeze… For the last time , that didn’t work !! I end of driving 20 mins away from home and my car start running hot ! I let it cool down and started back because I had to get home .. As I drove it would run hot and cool down . run hot and cool down.. Start making sounds… I did pull over to let it cool off !! Finally made it home and let it rest. I was told that , I need a heater coal too because water would leak inside my car when it rain … I’m thinking , I could need a new radiator.. But someone said as long as the radiator don’t have a hole in it , its fine .. It just need to be flushed from the bottom.. As I drove home , my car made funny sounds and it drove slow and picked backed up on speed.. Cool down and run back hot ! As I mentioned before … Water pump brand new .. But the thing is , the reason the heater coal was mentioned because.. My car wasn’t blowing out hot heat when I needed it too , cool air was coming out instead … I tried to mention all details .. I just hope , I didn’t blown the head gasket !!! I love my car and its been a good car .. Lol … Helpful details please ….

    • BlueDevil Pro on February 13, 2016 at 9:16 am

      Brittany,

      Thanks for your question about your 2005 Buick Lacrosse. The symptoms you’re describing could possibly indicate a blown head gasket, but before you take action there we’d recommend checking for other things like smoke in the exhaust, bubbles in your overflow tank or low compression in a cylinder. You could very well have clogs in your cooling system which would cause the odd overheating and your heater to not function properly. You can start by using BlueDevil Radiator Flush (available here: http://store.gobdp.com/radiator-flush-00204/) to clean out your cooling system and try and get things back to normal. If that doesn’t work, it may be worth testing for a blown head gasket before you replace your radiator and heater core.

      Thanks again for your question!

      • Spring on November 20, 2021 at 8:22 pm

        00 Suzuki vitara had a loss of power and overheated the other night. It hit the red but was turned off VERY fast and towed home. Radiator was busted. Today we replace the radiator and thermostat and then started it up. Ran smooth for a few and once it got to running temp it started running rough and loping. Had airbag light and check engine light on idk why. I tried to rev it a little and see if it was just wet from the coolant spraying all over the motor. It died on me. This car was turned off within 30 seconds of hitting the red it wasn’t driven hot. Can you help?

        • BlueDevil Pro on November 22, 2021 at 8:40 am

          Spring-

          Thank you for asking about your Suzuki Vitara. The first thing to address would be to figure out why it had a loss of power and overheated in the first place. Was the vehicle losing coolant prior to this? Based on your description, it may be best to bring the vehicle to an ASE certified mechanic for a proper diagnosis as to the cause of the issue.

          Thank you!

  10. Mackenzie on March 15, 2016 at 2:46 am

    I have a 1997 mustang gt, I haven’t had any problems with my anti freeze leaking or losing it quickly, but today my car overheated and was making a weird rattling noise coming from the engine every time I gave it gas. I got it home. There was anti freeze all over my battery and hood, so it was spraying, but I have a brand new radiator cap, and I had just put antifreeze in it 2 days ago. There are no visible leaks at all. There is white smoke coming from my drivers side exhaust only, and when I tried to put anti freeze in it, it just kept draining then flowing back up then draining again and flowing back up then checked it a couple minutes later and it was just completely drained but no antifreeze on the ground or anything. Tried pouring water in it to see if I could find a leak and there was nothing. First question, did I do damage by pouring the antifreeze in there and it just draining into where ever it drained, and then pouring water into it and it doing the same thing. Second question, what could this problem be.

    • BlueDevil Pro on March 30, 2016 at 7:32 pm

      Mackenzie,

      Thanks for your question about your Mustang. The first possibility is that you have a bad water pump. If your water pump is bad it could be causing the rattle you’re hearing when you step on the gas and coolant would most likely be leaking around the shaft and onto the pulley which would explain there is antifreeze all over your hood and battery. Try grabbing the water pump pulley and seeing if it is wobbly or loose or if the pump housing itself is loose. This would account for the overheating, loss of coolant and noise you’re hearing.

      You probably did not damage anything by pouring the antifreeze in as long as you poured it into your radiator or overflow tank. It could simply indicate that your engine coolant was really low, or it could indicate you have a bigger problem like a blown head gasket which could have happened when your car overheated and may be indicated by the white smoke from your exhaust. If there is nothing wrong with your water pump, this may be your problem.

      Thanks again for your question!

        I have a 2001 Chevy Malibu L’s 3100 sfi I just replaced my head gaskets, upper and lower intake gaskets. I burped the system and it idled fine with the expansion tank cap off but as soon as I put the cap on the upper hose becomes hard as does the lower and dumps coolant from the overflow tube I can’t go more than a mile or so before I have to open the bleeder/ expansion tank cap to get it to cool down. I’m having intermediate heat in the car then it goes cold and starts trying to over head The oil is normal I tested the thermostat and its opening up and the fans are working I have flushed the cooling system but it did little to nothing to fix the over heating issue

        • BlueDevil Pro on October 31, 2017 at 10:59 am

          Mike-

          Thank you for asking about your Chevy Malibu. Do you know if the heads were sent to a machine shop to have their surfaces smoothed? Based on your description, it sounds like you may be getting combustion/exhaust gases blowing into the cooling system and creating pressure. 
          We recommend applying 16 ounces of BlueDevil Head Gasket Sealer.  To give yourself the best overall chance of BlueDevil working successfully you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading.  If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.  Leave that plug out for the 50 minute idle in order to relieve the pressure from building up to allow the product to seal properly.  

          Thank you!

  11. Kasey on April 8, 2016 at 4:06 pm

    I have a 2000 jeep grand Cherokee limited last week something told me to check the oil so I did and there was none so I added 4quarts and it was fine there was no thing on the oil cap at that time so a week later I had to add another quart to it and when I did I noticed a light brown/tan film on the oil cap. The truck is not running hot nor is there white smoke coming out but I am losing oil and coolant somehow and today I noticed my oil pressure gauge dropping down to 20 at an idle but normal when I’m riding down the road. I’m praying this isn’t a head gasket issue because not even a yr and a half ago the engine was conpletley rebuilt because of a blown head gasket

    • BlueDevil Pro on April 13, 2016 at 7:06 pm

      Kasey,

      Thanks for your question about your 2000 Jeep Grand Cherokee. The first thing we would recommend looking into is if the rebuilt engine you have came with a warranty. If it is still under warranty we would recommend having the shop that installed it or rebuilt it take a look at an engine that new shouldn’t have leaks as bad as you’re describing.

      If you had to add 4 quarts of oil, then your engine was extremely low on oil and it is possible that running it that low has caused some internal damage which may have damaged seals or bearings which could account for the leaking oil and low idle oil pressure.

      As for the leaking coolant, since you only have 1 indication of a blown head gasket, we would recommend do a few other checks for leaking coolant like a cracked radiator or bad radiator hose. Until you find the source of the leaks or have the chance to the mechanic look at the engine make sure to keep the oil and coolant topped up.

      Thanks again for your question!

    • BD Auto Pro on June 20, 2016 at 10:33 am

      Shannah,

      Thanks for your question about your Pontiac G6. Usually, that much white smoke from your tailpipe indicates a blown head gasket. If that is the case you would also notice your coolant level dropping significantly along with bubbles in your radiator. That white smoke would smell sweet. If you do have a blown head gasket, use BlueDevil Head Gasket Sealer (available here: http://store.gobdp.com/head-gasket-sealer-38386/) to seal the leak without replacing your whole engine.

      As for your brake fluid, your brake system wouldn’t hold 5 bottles of fluid so you must have a leak somewhere. The leak could be in the leak you described in the center of your vehicle if it is a broken brake line, you should be able to simply replace that brake line then refill and bleed your brake system.

      Thanks again for your question!

    • BD Auto Pro on July 16, 2016 at 4:58 pm

      Tiffany,

      Thanks for your question about your Volvo S60. Usually, a blown head gasket does not cause a large oil leak like you’re describing. We find that often times problems after a large maintenance item like you had done car be related to something done during the maintenance. In this case, our guess would be a loose transmission cooler line is allowing transmission fluid to leak out. The place to start would be identifying the oil leak. Since you described the leak as “pouring” we would recommend checking for high pressure leaks like an oil cooling line, an oil pressure sender or a cam seal as they would cause very fast leaks.

      Thanks again for your question!

  17. Mike on July 8, 2016 at 12:25 am

    Hello, I have a 1991 Nissan 300zx non turbo. I have recently seen white smoke from the tailpipes in the mornings when I start it but only for a second. Also when I punch the gas I notice a white smoke screen but only when it’s not warmed up yet, I bet the cars behind me really dislike me in the a.m. Besides for that I do not see any coolant in my oil and everything else works as it should but 2 days ago I charged the AC with freon cuz it’s been so hot out and while I was driving around I noticed the car starting to overheat, it never had before. I had checked the coolant about 2 weeks prior and it was nice and green and full, after it overheated I got home and checked it and it was EMPTY. ?? So I filled it up with antifreeze it took the whole gallon almost. it’s only been a couple days and it tried to get over halfway on temp but i turned Ac off and it went back down checked water and it’s good- but my oil gauge is more reactive than it has been before. All I did was add coolant-not oil. Crazy right?? Any ideas?

    • BD Auto Pro on July 16, 2016 at 5:02 pm

      Mike,

      Thanks for your question about your 300ZX. You might check for a few more indicators of a blown head gasket before you decide that is your problem. First, try smelling the white smoke right on start up. Water vapor is normal on a cold start so if it doesn’t have an odor, it could just be that. If it smells sweet or feels oily it could indeed be burning coolant.

      Also, if you have coolant getting into your oil it could cause your oil gauge to act differently. Coolant in your oil will look milky white so you can check for that under your oil cap, or try doing a quick oil change and check the oil in the pan afterward for coolant or milky substance.

      If you do find a blown head gasket, you can use BlueDevil Head Gasket Sealer (available here: http://store.gobdp.com/head-gasket-sealer-38386/) to seal the leak and get your car back to normal.

    We have a 1998 Chevy Lumina and it has normally run good. I had the oil changed recently and shortly after when I was driving it, the temperature light went up into the high range. I took it right to the station to have them check it out. They replaced the water pump and then told me the head gasket is blown. No visible leaking only symptom was the high temperature gauge. We decided due to age of vehicle, high mileage, and expense of replacing the head gasket to take it off the rode. My husband drove it home (about 6 miles) and the temperature gauge stayed down (less than half on gauge) while he drove it home. He let it sit and idle for about 45 minutes in our driveway tonight and the temperature gauge stayed down where it normally does. Wondering if we should get a second opinion on the blown head gasket and whether we could continue to drive it short distances just in our area. Thank you. MG

      Margaret,

      Thanks for your question about your 1998 Chevy Lumina. Blown Head Gaskets can be a little difficult to diagnose as the symptoms can be confusing and can overlap with other problems. Becuase of this, we recommend looking for a few different symptoms besides overheating like bubbles in the radiator or overflow bottle, white smoke from the exhaust or milky oil. If you have multiple symptoms working together it is a good indication that you’ve got a blown head gasket. The best way to test for a head gasket is to have a pressure test done on your cooling system to see if there is a leak and most mechanics should be able to do that for you. If you do find a blown head gasket you can use BlueDevil Pour-N-Go or BlueDevil Head Gasket Sealer to seal the leak and keep your car on the road.

      Thanks again for your question!

    Hi! I have a 2001Chrysler limited town and country and just recently I started to Snell something from time to time. My van started blowing smoke but only when I’m in park for about 5 mins or so. when I stop for a while and then drive light white smoke comes out. What could that be??!!

    I have a 2005 Ford Mustang V6. Sometimes when I turn the engine off the radiator reservoir tank fills up all the way to the top and over flows through the cap. I noticed when it does this that the antifreeze in the reservoir tank looks like it is bubbling which I assumed was from it be extremely hot and is boiling. My questions is what could be causing this issue and what is the fix.

    • BlueDevil Pro on October 4, 2016 at 9:57 am

      John-

      We recommend using BlueDevil Head Gasket Sealer for your Mustang. It sounds like the vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure.  To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading.  If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.  Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.  Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

    Ok so I have a 95 jeep grand cherokee Laredo heater core was shot bypassed it. I just bought it it had all the signs of a blown head gasket I don’t know how many times its been overheated it only sign is white smoke in the exhaust and it smells like coolant. Now I don’t think I can keep it from overheating for 50 min will anything you sale fix this .

      Thank you for asking about your Jeep Grand Cherokee Laredo. In order to get the benefit of using the BlueDevil Head Gasket Sealer http://store.gobdp.com/head-gasket-sealer-38386/, the vehicle would need to be able to maintain idle for a full 50 minutes and you shouldn’t be losing more than about a quart of water/coolant during that 50 minutes. Based on your description, unfortunately, it sound like the vehicle is overheating a little too quickly for the product to be successful. A hard part repair may be your best option.

    I have a Honda Accord 1994 and when I start the car it shakes crazy and once I get off free way he temp gauge goes up I had just replace the heater hose and I went to get it diagnosed and the only problem is #4 vss temp sensor but does that have to do with the temp gauge going up and smoke coming from hood and muffler ?

    • BlueDevil Pro on December 1, 2016 at 9:35 am

      Justine-

      Thank you for asking about your Honda Accord. A faulty temp sensor could give the car the impression the vehicle is overheating, however, smoke coming from the hood and exhaust pipe indicates that you are losing fluid and it is burning off. Have you noticed a loss of water/coolant? We recommend taking the vehicle to a certified ASE mechanic for a 2nd opinion.

    I have a 2000 Ford Escort ZX2. I bought it recently and it pushes white exhaust all the time. I have to add around a gallon of antifreeze a week (I usually have to top it off every morning so I can get heat). I recently started getting a misfire in cylinder 1 but I think that may be my ignition coil and that it may not be related to the coolant system problem. It sometimes does have a very very small amount of white smoke come out of the hood sometimes (haven’t been able to figure out why it does it or if there is a pattern to when it does or doesn’t). I have not seen any antifreeze in my oil yet (I’ve owned the car for ~15k miles and done 5 oil changes). I think it may have started around 6k miles ago. In your opinion what is it: A. Blown head gasket; B. Intake Manifold Gasket; C. Cracked engine block; D. Cracked head; E. Crankcase?
    Thanks in advance BDP

    I have a 2000 Dodge Durango 5.9L. I just recently replaced the radiator due to it leaking out the bottom. I also have replace the thermostat, water pump, and the clutch fan. If I am sitting still letting it run the heat is great but when I take off driving it within a couple mins the heat goes cold. It is not overheating after I replaced the radiator. I just flushed out the heater core about 20 mins ago and still having the same problem once I start driving the heat goes cold. I stopped at the gas station and within 3 mins it is putting out heat again. I don’t know what else to do and someone told me that I probably have a cracked head not just a bad head gasket. Please help as this is my daily driver.

    • BD Auto Pro on December 19, 2016 at 6:32 pm

      Brian,

      Thanks for your question about your Dodge Durango. Based on your description of the problem, you may consider checking the thermostat you installed. If you had a colder thermostat installed, like maybe a 160-degree thermostat it would cause the lack of heat while driving that you’re experiencing. If you’ve got an infrared thermometer, you could try checking the temperature of the thermostat housing after a drive that causes the heat to go cold. If the temperature is low, then you should install a new higher temperature thermostat.

      One other thing to check would be the actuator for your heater blend door. I believe on your truck it is a vacuum actuated module so if there is a vacuum leak in the line, it’s possible that during driving while vacuum is low it allows the blend door to move cause the air to not be heated and blow cold.

      Thanks again for your question!

    Hey there i have a 92 toyota 4runner with a possible head gasket issue just looking for some additional advise, today when trying start it it would not crank (almost like it was sized) for the first 2 trie, and then it sputtered up without even cranking. it started blowing out some pretty white smoke that defiantly did have a sweet smell to it. it was idealing pretty rough and a had a bit of a shake to it. but once i started driving it ran fine. until i noticed the engine temp was dangereously high, i pulled it over to let it cool down. tried turning on the cabin heater to help it cool down but for some reason it was not putting out any heat.

    Reasons why i think it is a head gasket:
    -Sweet smelling white exhaust
    -over heating
    -very low coolant levels (little leaking near front left of engine well)

    Reasons why i think it may be something else…
    -no milky oil
    -no heat moving in from engine to cabin
    -previous power steering pump sounding whine instantly went away
    -coolant resivour very low and can not see any bubbling or coolant for that matter at top of rad when running

    any ideas guys?? please help!!

    Hey there,i drive a grand Cherokee limited Jeep 2004 model.The jeep was over heating and I got it fixed,it later started stoping while driving and refuses to start again and when forced,make a loud shooting sounds from the tail pipe.They said it was due for servicing which I’ve done,but now it drips oil from the engine and produces brownish oil with black stains from the tail pipe. The Jeep also vibrates when started and continues until it’s turned of,i can’t use my Air condition because a friend says the engine is weak. But the Jeep runs normal with a bit of vibrating noise underneath when accelerating. Miles already covered 180,250.thats what is displaying on the board. But the temperature gauge and the oil gauge is normal,pls what do I do could this be a blown head gasket problem? Your advice guys and truly down now cause this is my only drive.

      Thank you for asking about your Jeep Cherokee. It is a little difficult to say whether or not it is a head gasket problem, as you do not have any of the tell-tale signs of a blown head gasket. Based on your description, it sounds like you are losing oil, possibly from the head gasket. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. Unfortunately, we do not manufacture a product meant to stop oil loss from the head gasket. A hard part repair may be your best option.

    I have a 1988 Chevrolet Cheyenne 1/2 ton, 4.3L V6, truck, here about 3 weeks ago my antifreeze and water froze in my radiator. I however didn’t know that it froze. With it frozen I drove 13 miles and started loosing power and went to stop at a gas station and as I pulled onto the lot my truck died and would not start back up. I then proceeded to push it to a parking space and check the radiator out. I then found out that it was all ice inside, I also blew the plastic drain plug. I first checked the oil and all was fine still no water in it after 3 weeks. I got everything back to operating order. I now have problems keeping the motor running when I go to stop, and the whole truck shakes when driving it. It also seems like it has no power to climb any incline and a week after it was frozen some how the oil in the engine was gone. And no oil leaks. Would my head gasket on my exhaust side be blown and sending the oil into the exhaust?

    • BlueDevil Pro on January 20, 2017 at 9:27 am

      Shawn-

      Thank you for asking about your Chevrolet Cheyenne. Based on your description, it sounds like you may have blown the head gasket when you initially drove the vehicle with the frozen water mixture in the cooling system. The fact that you have since lost your entire oil capacity suggests that it may be getting sent back into the exhaust. Are you noticing any smoke coming from the exhaust? Unfortunately, the BlueDevil Head Gasket Sealer is only intended for water/coolant leaks, so it would not be able to help with the oil loss you are dealing with. A hard part repair may be your best option.

    Hi, I have a 96 Honda Civic and I’ve recently just gotten a full tune up. After that a bypass hose broke and the engine overheated. I was told by my mechanic that I should keep an eye on the fluid levels. I checked one morning and they were totally fine, drove home parked no problems. I went to start my car later that night and lots of white smoke from the exhaust and the coolant reservoir was at a lower level. Checked the oil and it isn’t milky. Any knowledge you could pass on?

Got the battery check, battery was dead, got it charged. Now, I tried starting it, but I saw that the coolant reservoir is bubbling while attempting to start it. Does the Pour and Go Head Gasket sealer works in this type of issue, and do I need to flush the anti-freeze before I pour the product? and will it start after using the product? Thank you in advance!

      Jason-

      Thank you for asking about your Son’s Kia Optima. Based on your description, it is possible that you are getting combustion/exhaust gases pumping back into the cooling system.  You can use a “Block Dye Tester” to confirm whether or not that is the case. If this is the case, we recommend the BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386) for best overall results.
      BlueDevil Head Gasket Sealer will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure.  To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading.  If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.  Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.  Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

      Thank you!

    Hi blue devil pro, I own a 1997 honda accord 4 cylinder with a little over 200k miles on it. Lately I’ve noticed some white smoke coming from my exhaust when it’s cold in the morning. The smoke lasts for about a minute. I recently had a very small leak in the center of my radiator, which I was a able to stop with a stopleak product. I’ve also got a small power steering leak which I’ve recently treated. Ive also noticed a burning smell coming from under the hood when im stopped and when i leave the car. The temperature never goes above half way but it seems got under the hood. There is a small oil leak and the automatic transmission shifts hard at times. But im not losing any antifreeze and it doesnt overheat. Any thoughts? Suggestions? Thank you, imput is appreciated.

    I have a milky misture in my coolant resovoir , but not in oil pan or on the oil cap. No other signs of blown head gasget except milky misture in coolant resovoir . How do I clean this up and would it be good to use head gasket sealer? I changed oil and tried to flush it, but still getting milky. It’s a 1992 Volvo 940 GL. Took it to pep boys and they said I had a blown head, but not understanding how it’s not on oil dipstick or in the pan.. Just in the plastic resovoir .

    • BlueDevil Pro on March 10, 2017 at 11:16 am

      Thank you for asking about your Volvo 940 GL. Based on your description, it sounds like you may be getting oil back into the coolant reservoir. Unfortunately, we do not manufacture a product intended to stop this type of a leak. A hard part repair may be your best option.

    I have an 03 Kia Reo. We have had continuous problems with excellerating after a full stop. It spudders like as if its having an issue feeding the gas. It doesn’t heat up really fast as well. Takes roughly two minutes to heat up. It uses up gas fast as well. It has stalled on me three times and lost all power. It did start up again when the engine cooled off a bit. We have had the sensors replaced, the spark plugs and plug wires replaced as well. There is list, it would be alot to type. But yet, still the same issue.

    • BlueDevil Pro on March 22, 2017 at 9:55 am

      Thank you for asking about your Kia Rio. Based on your description, it sounds more like a dirty/clogged fuel injector than a blown head gasket or leaking head gasket. We recommend using the BlueDevil Fuel System Cleaner (http://store.gobdp.com/fuel-system-cleaner-00202/) to clean the fuel lines and get rid of any possible restriction in the system.

    I have an 07 Chevy Malibu 2.2 liter 4 banger
    I have exhaust coming through the coolant system and bubbling into my coolant over flow tank. I have an overheating issue, which I’m assuming is coming from this.. the car runs hot but never quite over heats all the way. I’ve flushed my system, and even torqued the bolts in the head down better as who ever was in there before hasn’t done it completley. Blown head? I’ve purchased the blue devil but I’m not sure if it will work or not…

      Thank you for asking about your Pontiac Grand Prix SE. The tapping sound you are hearing is most likely a sign of water/coolant being in the oil.

As long as the vehicle will maintain idle for a full 50 minutes, and you are not losing more than about a quart of water/coolant during that 50 minutes, you would be a great candidate for the product.

    Ford F150 5.4 L engine has developed a leak between the cylinder head and engine block. At first I could see it leaking and spraying under the intake manifold. I tried another brand of sealer. Seamed to work for a few days, but them I determined that is had blocked my radiator. So I flushed the entire system. There is now flow and I have driven the truck and it has not run any hotter than normal. However I have been having to add water. Yesterday I discover that with the expansion bottle (pressurized my truck doesn’t have a radiator cap) open that water pours from a spot I can’t see lower passenger side of the truck and has trickle in the passenger head area. I topped the water off, put the cap back on and it stopped leaking. So I ask now what????

        If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring BlueDevil through the reservoir/overflow, with the car off and engine cold you should disconnect the top radiator hose and add the product there (it may be added into the hose or through the opening).  Once it has been added reconnect the hose and start the idle from that point.

Is this my head gasket and would your product seal it. Also how long does it last do I need to use it several times etc?

      Once the product seals, it would be a permanent seal. If you are indeed experiencing the symptoms of a blown head gasket, you should only need to use the product once.

    I have a 2013 Chrysler 200. When I’m constantly driving the car thermostat is normal and the car operates fine. In stop and go traffic the motor temperature gauge will go up and eventually to hot. If I return to the expressway or constant driving the temp. gauge will go back down. My fans are working. I had a mechanic look in the radiator to add coolant and quickly said your coolant has turned a white cream color. That means you have a blown head gasket. What do you think? Also how do you use Blue Devil? Should I change my oil, flush my radiator, add new coolant and then add blue devil to the radiator or oil. Is it a possibility the Blue Devil will clog other parts of my engine.

If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.

Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.
      The BlueDevil Head Gasket Sealer does not contain any solid or particulate matter, so it is a non-clogging product. Also, if you are indeed getting water into the oil, we recommend changing the oil before and after the BlueDevil process.

      Tori-

      Thank you for asking about your Chevy Cavalier. Based on your description, it is possible that the recirc door is stuck open, pulling in hot air when the vehicle is at idle. The recirc option is pulling air from the engine, which if the vehicle is overheating at idle, would be pulling in hot air. Unfortunately, there are a number of different reasons why the vehicle may be overheating in the first place. We recommend taking the vehicle to a certified ASE mechanic for a proper diagnosis.

And she said it wouldn’t start a couple times. I got it to start. I think its the head gasket. Ne one else think the same n will the blue devil wrk if that’s the case r is it to late for that? Thanks

      Thank you for asking about your Pontiac Montana. As long as the vehicle will maintain idle for a full 50 minutes, and you are not losing more than about a quart of water/coolant during that 50 minutes, you would be a great candidate for the BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/). Feel free to contact our technical support line at 888-863-0426 with any other questions.

    Hey blue devil I replaced exhaust manifold dorman bolts and gaskets on both sides and did proper ft. and Newton metric weight also added new oil filter and oil not sure if engines actin cause I needed sythetic oil with some Lucas additives when I didn’t know till after reading but I added shell 5-30 lubricant oil and didn’t add seafoam additive till next day but after I shift into gear car starts to over work it self causing hoses under the hood to boil after 10 -15 minutes . Not sure if exhaust fumes are entering combustion chamber like u said in your forum but I added bars and leaks gasket head and block sealer but doesn’t seem like it worked only because your blue devil product was high demand out of stock where I went oreilly and AutoZone but bars and leaks was next in line . First manifold was leaking oil so I fixed that it stopped then clouds of white smoke pouring out the back I thot sealer should of worked so must be carbon build up in catalyst cause was dripping black liquid out tail pipe after seam foam treatment in the throttle body but now it’s causing more problems I’m thinking head gasket like you guys were diagnosing and I’ve tried obd reader but code is glitching Everytime also have small exhaust leaks but im sure that wouldn’t cause the boiling and thick white smoke but I was just tryna see if I should buy ur product cause I’m kinda homeless living in motels with kids till my fitter job falls into affect tryna get to work is all so I’m low on funds but I heard great reviews on your products so I know you guys are knowledgeable might be able to help me thank you if u can help deeply appreciated Also forgot to mention it’s the dreaded 2001 Dodge Durango 4.7 l V8

      Jeff-

      It is possible that you are getting combustion/exhaust gases pumping back into the cooling system. You can use a “Block Dye Tester” to confirm whether or not that is the case. If so, we recommend using the BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/). You would also want to thoroughly flush the cooling system prior to use.
      BlueDevil Head Gasket Sealer will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly. Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

    I have a 2004 Ford F250 with the 5.4l V-8. I noticed that the coolant was at the low level line and when I topped it off it drained back to the low level line. I did this a couple of time over a 30 minute period and was not able to see any visible leak onto the concrete below or anywhere on the engine.

      In order to get the benefit of using the BlueDevil Head Gasket Sealer, the vehicle would need to be able to idle for a full 50 minutes. If you are unable to get the vehicle started, unfortunately, the leak or symptoms you have may be a little too extreme for the product. A hard part repair may be your best option.

    Hi BlueDevil Pro, please I want to know the cause and solution of over smoking of my Toyota Camry 2008 model. Before it started smoking yesterday, I first noticed that the engine oil is coming into the radiator, hence missing up with the radiator coolant. And the coolant is now spitting out from the radiator chamber. Please kindly assist me, warm regards.

    • BlueDevil Pro on October 18, 2017 at 10:27 am

      Charles-

      Thank you for asking about your Toyota Camry. To confirm, the white smoke is coming out of the exhaust pipe? Are you noticing a loss of oil, or does the coolant just appear to be contaminated with an oily residue? It is possible that you are getting combustion/exhaust gases pumping back into the cooling system.  You can use a “Block Dye Tester” to confirm whether or not that is the case.
      BlueDevil Head Gasket Sealer will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure.  To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading.  If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull.  Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly.  Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

    2003 toyota avalon overheated in stop and goo traffic.. let it cool down.. next day, took it to garage,,they charged $85.00 for diagnostic, replaced thermostat.. few weeks later overheated again took car to dealer.. replaced cooler fan.. couple weeks later.. sitting with car idling.. starting sputtering and died.. would not start.. called tow truck to take to original garage to fix as they had original diagnosis ,,suspected installed thermostat wrong or wrong diagnosis wrong.. now new diagnosis is head gasket blown. at 2000.00 and paid dealer $688.00 for engine fans not needed. shady garage should be responsible for the 688.00 and near 2000.00 as over pmt.. if they would have fixed it right first time the rest would not be necessary.

      Virginia-

      Thank you for asking about your Toyota Avalon. Yes, it seems that further diagnostics needed to be run in order find out what was wrong with the vehicle. Unfortunately, without taking the engine apart (which would have been quite costly), it would have been hard for the mechanics to know it was a blown head gasket, as it didn’t have any of the tell-tale signs of a blown head gasket at the time of you first bringing it in.

    I have a 1999 Dodge Ram 1500 (8cyl, 4×4) with over 230,000 miles. A month ago I was driving over a mountain and the truck suddenly started to lose power. I had to replace the spark plugs but the #8 keeps fouling out and can’t figure out why. A few days ago the truck overheated out of nowhere. Put the heat on to get home (20 miles) and added antifreeze. No problems for 3 days (only drive about 40 miles a day) and then today when I went to start it the truck started blowing a grey (or blue?) smoke. Had a few quick errands which meant driving, turning truck off, coming back after 15 minutes and driving to next stop (within a mile of each other). The smoke steadily decreased and the truck seemed to run really smooth (better than before the smoke started because of the #8 cylinder fouling out). The only noticeable problem was the truck started to overheat again after driving about 15 miles today. I put anti-freeze in when I got home. There is no visible leaking of anti-freeze. When I first looked today I didn’t think water was getting into the oil but after checking again I believe it is. Any advice would be appreciated.

    I’ve got a very strange problem with a 98 Explorer, The engine is not overheating and is not losing coolant, The temperature gauge is at normal operating temperature at Idle and when I get around 2,000 to 2,500 rpm’s the engine temperature drops 60 degrees, I still have heat and it will not overheat but at anytime the engine is running it pushes large amounts of coolant out of the radiator when I take the radiator cap off, It started doing this 2 month’s after i done a complete overhaul of the engine, I figured it had a cracked head, I completely flushed out the system put new antifreeze in it and put Blue devil pour and go in it, That was 4 days ago and it is still is having the same symptoms, Any advice would be helpful !!!!

    Is it possible for water to seep through your pistons after the motor shutting off because of water getting sucked in though the tail pipe and standing on them? It happened to me earlier. I had to replace all the spark plugs and air filter but before hand I had to take all of the plugs out and turn it over to get the water off of the pistons

      If the vehicle was getting combustion/exhaust gases blowing into the cooling system, the system may become over-pressurized and force water/coolant to get back into the cylinders. This is typical of warped/cracked heads. Have you noticed any bubbling or boiling over in the cooing system or experienced any issues with overheating?

        I have a 06 equinox that is making a slight knocking sound when I start it. While it’s idealing it seems to fade away briefly then comes back. This is consistently what it does idealing. The guy I bought it from just replaced the head gasket. Then his neighbor cut the cat off, so he decided to sell it. I’ve since replaced the catalytic converter and installed new seals, and o2 sensor. But it is making a slight knocking sound while idealing that fades away briefly then comes back repeatedly. I’m wondering if I need to replace the heads also. He also stated that he timed it by ear rather then putting #1 cylinder top dead center. Or could it be timing not set right, like he said was the reason for the knocking sound. I’m not overheating and it seams to drive nicely. Also not leaking anywhere I can see.

        • BlueDevil Pro on September 22, 2022 at 8:48 am

          Tina-

          Thank you for asking about your Chevy Equinox. Based on your description, the most likely cause for the knocking would be timing not being set correctly or there may be a carbon build up in the combustion chambers or on the cylinder walls themselves. Being that it doesn’t sound like you are experiencing any other issues, it does sound like a timing problem.

          Hope this helps!

  81. Mike on April 29, 2019 at 10:17 pm

    I have a 2002 Audi A4 V6 that has a vibration problem where the whole car shakes on even the slightest gas pedal press, but only after the car has been running for at least ~22 minutes and has warmed up. I haven’t yet isolated whether it’s from the engine being hot or the body/wheels but it definitely doesn’t shake while cold. Was told it’s a head gasket issue by mechanic due to coolant/oil being mixed. Car also has coolant loss issues, but after further research am not so sure. I’m leaning toward it being an ignition coil or CV axles/wheel bearings/tie rod ends.

    However it’s worth noting that the radiator expansion tank would erupt out water and leak once cap is unscrewed while hot. That water had a rainbow colour to it on the ground suggesting oil got in there? Oil cap had traces of water too according to mechanic, but I can’t verify.

    The onset of the shaking starts off gradual and becomes worse the longer the car is being driven (hotter?) until stopped and cooled down. Letting go of the gas pedal stops the shaking immediately at all speeds.

    Update: I had applied a local head gasket stop leak, the problem has improved and became an intermittent issue. The shaking isn’t as severe and happens almost exclusively at highway speeds now (80kph+). After a few days of warming up and cooling down the car in the driveway, I let the car idle for 51 minutes before performing a 1 hour 30 minute drive involving motorways in which it only really noticeably shaked at high speeds! Turning on the heater also somewhat helped reduce the shaking once it crept in, but that could be placebo though.

    What could cause such temperature related shaking symptoms like this? Should I do a flush + re-application using Blue Devil this time? Thanks

    Hello sir, my Honda accord v6 2003 model has been consuming coolant, I fill coolant with 10litres of coolant everyday. Now, I have changed the head gasket twice within a week, the coolant is still mixing with oil. And water is gushing out of the exhaust pipe when u rev the car. Could it be cracked block/cylinder? Can ur product solve this or I need engine replacement

      Thank you for asking about your Honda Accord. Based on your description, unfortunately, it sounds like you are losing coolant a little too quickly for the BlueDevil Head Gasket Sealer to be effective. In order to get the benefit of using the product, the vehicle would need to be able to idle for a full 50 minutes, and you shouldn’t be losing more than about a quart of water/coolant during that 50 minute run. Perhaps having the heads sent out to a machine shop to be smoothed would be your best option.

    Good Day. I hope this forum is still open. I have a Nissan Terrano II 2.7 TDI. The car started behaving funny awhile ago. Lately is struggle allot to start as if it is not getting heat from the glow plugs, but they tested fine, and I have to keep my foot on the pedal to get it t warm up. If I press down on the accelerator to get high revs then it is fine, if i suddenly let go of the accelerator pedal to idle then it also is fine, BUT as soon as I touch the accelerator pedal to slowly pick up revs then it starts to stutter and smoke heavily, until I rev it up a bit then it is fine again. I did had to add a 1 liter of water and almost 2 liter of oil. the color of the smoke varies from white to blue and I can smell un-burned fuel. does this sounds like the beginning of a blowing gasket?

    • BlueDevil Pro on June 17, 2019 at 1:51 pm

      AndreV-

      Thank you for asking about your Nissan Terrano II. A blue smoke would indicate oil burning, where a white smoke/steam would indicate water/antifreeze burning. It is not typical that you would be seeing variations of both coming out of the exhaust pipe, however, it is possible and would be a tell-tale sign of a blown head gasket. Having the head gasket replaced may be your best option.

    I bought My 2017 Dodge Grand Caravan (3.6 liter eng) in November with 58k miles, early after purchase a mech replaced the water pump when the heater stopped blowing heated air which did fix that issue. it now has 94,000 in July (I’ve used it as a taxi). All winter/spring the oil pressure seemed to always be 44psi while driving and 33psi at idle,the oil temp a consistent 195 and coolant 203. Just got the oil changed last week and the last couple weeks the oil pressure seems to be dropping slowly, last week it was usually 38-39psi driving and 28psi at idle/coolant temp running around 220-230 and oil temp at 203-213,then 34-36psi driving and 24psi at idle, last night it dropped as low as 22psi at idle and seems to fluctuate more while driving but still usually between 33-38psi but it will sometimes raise as high as 70psi if i’m heavily accelerating before dropping back to the 34-38 range and at one point I thought it smelled hot, kind of like burning rubber to me . The gas mileage is still consistent if that matters Just how concerned should I be about the van’s longevity? (especially if it keeps getting lower in a short time!)

      Matthew-

      Thank you for asking about your Dodge Grand Caravan. Based on your description, the best advice would be to make sure you are keeping up the routine maintenance on the vehicle and having it serviced at regular intervals. You can read more on some tips for good routine maintenance on our blog titled, Car Maintenance Schedule (https://gobdp.com/blog/car-maintenance-schedule/). With the amount of miles you’ve put on the vehicle in such a short amount of time, it would warrant multiple oil changes. At this point, it may be a good idea to have a engine oil flush performed, replacing the filters and refilling it with fresh, clean oil. It’s possible that sludge or engine build up is the cause for the decrease in oil pressure.

      Thank you!

    Very interesting stuff
    I have a 2003 monte Carlo ss eith a 3800 engine. It over heated 1 time last week. And again the other nite neddel did not show it getting hot. Was at dream cruse made 2. cerits around woodward engine was kina bucking at lo speeds. So I decided to go home so I would not get stuck in dream cruse traffic . I was on the main drag and decided to to get on freway .as I did. I was transisanig to a nother lane started to add power and saw my speed o go down
    Engine quit no rpm. I quickly looked for a exit. got off exit made it to right lane steam comming from under hood pushed it in to empty parking lot opend hood stesm comming from back of enigne at fire wall….turn on temp gage on car it was not in the red. I let it cool down over an on hour add warm water cause I was told adding cold water could crack the head. After lett it set I went too crank it over it mad a like a thumping noise like a hard crank and i saw the rpm go up to about 700 to a 1000 and quit…..so I decided to let it cool some more after another hour it cranked like normal but would not stay running…had it towed next morning it started but noteced with radiator cap off wster squirting out of radiator…..so now I gess thats a singe of a head gasskit……?

      Bernie-

      Thank you for asking about your Chevy Monte Carlo. Based on your description, it’s possible that you are getting combustion/exhaust gases pumping back into the cooling system. You can use a “Block Dye Tester” to confirm whether or not that is the case.
      BlueDevil Head Gasket Sealer will still work if your vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. To give yourself the best overall chance of BlueDevil working successfully, in addition to the directions, you should remove the spark plug from the cylinder with the leak; this will be the spark plug from the cylinder with the low compression reading. If you are not sure which one that is, you may pull all of the spark plugs and will notice one will have a white-crystal-like substance on it and/or may look dirty; this is the plug you should pull. Leave that plug out for the 50 minute idle in order to relieve the pressure from building up and thus allowing the product to seal properly. Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

      Thank you!

    Hey, BlueDevil.

    We have a 2001 Toyota Tundra V8 with 180k miles. It has started blowing coolant. It doesn’t overheat. It will empty the reservoir in a couple trips around town. I replaced the radiator cap and it didn’t fix the issue. I don’t see any leaky hoses. Fluid appears to be shooting up somehow between the radiator and fan housing and hits the top of the hood dead center in front. It drys quickly and leaves white spots and residue on the underside of the hood, the engine and top of radiator. What advice do you have?

    Thanks,

    GMan

    • BlueDevil Pro on December 2, 2019 at 9:41 am

      GMan-

      Thank you for asking about Toyota Tundra. Based on your description, unless you are seeing white smoke/steam coming out of the exhaust pipe or water/coolant getting into the engine oil, it doesn’t sound like what you are experiencing is head gasket related. You can try performing a block/dye test. This will test for combustion/exhaust gases pumping back into the cooling system. If that is the case, you would usually have an overheating issue. An air pocket can give you similar symptoms, so bleeding the system would get rid of any excess air.

      Hope this helps!

    turned on my 96 honda prelude. and left it at idle for 30 minutes, then went to drive it, but not after driving more than 200 feet i noticed the temp gauge starting to increase then white smoke and some liquid dripping out the tailpipe immediately after. I instantly pulled the car over nor more than 20 parking spaces down from the one I was at in my apartment complex and turned the vehicle off. the smoke then faded away and I went back to my apartment for a couple hours. after letting the vehicle cool down i checked the under the hood. I saw two things. 1 my coolant reservoir was bone dry and that a coolant hose leading from the engine to the bottom of the throttle body was weahter and had some dried green bubbles around the cracks. what do you think i can pinpoint as the problem?

    • BlueDevil Pro on February 18, 2020 at 8:39 am

    Hi I have a 2001 honda accord and it has recently started to leak the coolant I checked to see if it was the new pipe I put but it’s not leaking from there. I plan to drive back home from college tomorrow its an hour drive, should I be okay driving it?

    • BlueDevil Pro on February 28, 2020 at 9:33 am

      Diana-

      Thank you for asking about your Honda Accord. Is the vehicle overheating at all? Depending on how quickly you are losing coolant, you may still be fine in driving the vehicle home. You will want to constantly monitor your temperature gauge, and should bring a couple of gallon jugs of water with you to top off the system if needed.

      Hope this helps!

    I Have a 1998 Isuzu Rodeo 3.2 V6 engine, And my question is I know they recommend that you remove the Thermostat before adding Buledevil But it not easy to get to it unless i remove the intake manifold, and the they want you to go through the process and then reinstall a new thermostat back in, which means i would have to remove the intake manifold again, what could happen if i just leave the thermostat in?

    • BlueDevil Pro on April 23, 2020 at 8:24 am

      Adrian-

      Thank you for asking about your Isuzu Rodeo. You may use either Head Gasket Sealer we manufacture to treat your vehicle. The “Pour N Go” (http://store.gobdp.com/pour-n-go-head-gasket-sealer-00209/) is a less concentrated formula that does not require the removal of the thermostat or a flush of the cooling system prior to use. Whereas the “Mechanic Approved” (http://store.gobdp.com/head-gasket-sealer-38386/) requires both the removal of thermostat and a flush before applying the product; the 32 ounce is the more concentrated formula.
      The product with the yellow label will give you best overall results as long as you can remove the thermostat and flush the system prior to use. However, if the thermostat is difficult to remove or you would rather not then you can still use the Pour-N-Go Head Gasket Sealer.

      Thank you!

    If I put transmission fluid where the power steering is and the power steering where the transmission should go would it turn my engine oil milky white ? And if no , why would my engine oil be milky white ?

    • BlueDevil Pro on August 27, 2020 at 9:08 am

      Candice-

      Milky oil is a tell-tale sign of a blown head gasket. It indicates water/coolant getting into the engine oil and wouldn’t really be related to adding power steering fluid to the transmission or vice versa. As long as you are not losing water/coolant too quickly, you would be a good candidate for the BlueDevil Head Gasket Sealer.

    Hi, I have a 2009 Suzuki Grand Vitara. The temp went to hot , I pulled over and had car towed to mechanic who told me the alloy head was warped , head gasket cracked and that i need a new engine at a cost of 8-9k. I suggested we could try head gasket sealer to which he agreed may work, Since getting car back the temp has fluctuated whilst driving short distances, when i pull over and rev the engine the temp guage comes down. I am checking the water level daily and have had to top it up. Is there anything else i can try or does it sound like i need a new engine?

    I have a 2002 Durango.
    For a couple weeks , I drove the truck around normally (and didn’t know that I was low on antifreeze).
    It overheated multiple times in those few weeks , and when a friend looked under the hood he said I needed coolant.
    So I added coolant, and the temperature was back to normal!
    But- now I have to add coolant every 50-60 miles and every now and then after start up I have smoke from tailpipe for a few minutes then it clears up and goes away.
    But still- gotta add more coolant every couple trips. Do you think it’s a blown head gasket??

    • BD Auto Pro on October 20, 2020 at 9:45 pm

      Mikey,

      Thanks for your question about your 2002 Durango. If you’re losing that much coolant it must be going somewhere so it’s either leaking externally or internally. If the leak is external you should be able to see some evidence of it like steam or build up around the leak point. Depending on what motor you have sometimes leaks can happen at the timing cover or water pump and be hard to detect. It’s also possible you have a blown head gasket but we would recommend checking for more of the signs of a blown head gasket before jumping to a conclusion.

      Thank again for your question!

    Hi, I have a 2003 Honda pilot. Just had the transmission and differential fluids changed, as well as replaced the timing belt and both serpentine belts. Any two weeks later I started feeling a heaviness in underneath the car, like something was rubbing. A few days later while my son in law was driving it on the free way it overheated and the A/T temp light came on, he immediately pulled over because the car started smoking. He said there was a huge fluid leak that looked like oil. He also said that it smelled like burnt rubber. Haven’t had it diagnosed yet, I just had it towed to my garage. Could it be a blown gasket?

    • BlueDevil Pro on October 21, 2020 at 8:33 am

      Josette-

      Thank you for asking about your Honda Pilot. Unfortunately, it would be difficult to diagnose what happened in this instance, however, it does not sound like you have any of the tell-tale signs of a blown head gasket. Water/coolant getting into your engine oil and/or white smoke coming out of the tail pipe are typically what you would see if the head gasket was blown. Having the vehicle diagnosed should point you in the right direction.

      Thank you!

Got it fixed bit 2 days later soon as I parked heard an explosion under the hood and all fluid instantly ran out. Runs hot again.

      Thank you for asking about your Honda Accord. The tell-tale signs of a blown head gasket are water/coolant mixing with the engine oil or a white smoke/steam coming out of the exhaust pipe.

    Hi, I have a 2006 Jeep Cherokee 3.7, I started having over heating issues initially thought the thermostat and fixed that, flushed the coolant and added new. Seemed to fix, car had heat, was no longer overheating, drove it to work that night, no issues! The next day I needed to make a short trip so I chose to take the highway, the entire trip to get to the highway, no issues, about 20 minutes and almost to my destination on the highway, car stated that is was over heating once again! Pulled over let it cool off popped the hood so smoke no actual sign of overheating except what the computer was saying, was able to get it home. Next, we replaced the water pump, I headed to work! Not even 10 minutes on the way to work, car started to overheat once again! (Well that’s what the computer said but again no sign of smoke, Pulled the car over, allowed it to cool, started the car and headed back home( 10 extra minutes) car says overheating again, popped the hood, no visual signs of any smoke! But now my radiator fan stopped working!! Last thing I could think to do was replace the coolant temp sensor, got that replaced turn the car on, radiator fan not working and didn’t get any signal that the car was overheating, but now! My heat is not working again! I am so frustrated!! I cannot understand what is wrong! Beside replacing everything except for the heater core or radiator. Please help!! I’m losing my mind. I really need just a little more time with my car! Can’t wait to hear from you.

    I have a 2005 escalade 6.0 , yesterday my wife took it to the store and al of a sudden then engine started making a metal on meta sound and was blowing white smoke , now when I try and start it the metal on metal sound happens and it’s not the starter but also blows white smoke when I try and start it. Could this be head gaskets , cracked head , or a timiming chain issue? Any help will be very much appreciated thanks.

    • BlueDevil Pro on May 23, 2022 at 9:07 am

      Jonny-

      Thank you for asking about your Cadillac Escalade. White smoke blowing from the exhaust pipe would indicate that coolant/water is leaking and burning off. The metal on metal sound could be an indication that the cooling system is very low and needs coolant. Make sure the cooling system is topped off with water/coolant and then see if the problem persists. If so, it could be the beginnings of a blown head gasket.

      Thank you!
