Seal Your Gasket Before it Gets Worse

Can You Drive With a Cracked Head Gasket?

Symptoms of a Cracked Gasket

How can you tell if you have a blown head gasket or a cracked head gasket? Before you can understand how to fix your problem, you have to make sure that you’ve diagnosed it correctly. A cracked or blown head gasket will demonstrate one if not all of these issues:

  • Overheating Engine
  • Low Coolant Levels
  • White Smoke 
  • Oil and Antifreeze Mixture

Is it Safe to Drive? 

To understand why it’s a bad idea to drive with a cracked or blown head gasket, you need to understand what is actually going on in your motor.  The head gasket in your car is sandwiched in between your engine’s block and the cylinder head, forming part of the combustion chamber.  Its job is to keep compressed air and fuel inside the cylinder so it can be ignited and turned into energy. It also keeps coolant and oil out of the combustion chamber, so they don’t foul the ignition process or cause your vehicle to lose fluids.

When your head gasket is blown, it allows one or more of these fluids or gases to get to a place they shouldn’t be.  A blown head gasket can allow combustion gases to get into your coolant, engine coolant to get into the combustion space or  your oil. It may also let engine oil get in all of these places as well. The danger of driving with a blown head gasket is really the danger of driving with your engine’s fluids and gases in the wrong places. 

What Happens If You Drive With a Cracked Gasket? 

Allowing coolant into the combustion space can cause lots of problems.  First, it can foul spark plugs and make your engine run poorly due to the deposits left by burning coolant. Next, coolant in the combustion chamber can change air fuel ratios and cause damage to sensors. Lastly, and possibly most hazardous to your engine, having coolant in the combustion chamber can cause rusting of the piston, piston ring, and cylinder wall. As a result, you may experience lower compression that requires a complete engine rebuild.

Additionally, you could end up with coolant in your engine oil. Coolant in your engine oil causes major problems as it significantly reduces your engine oil’s ability to lubricate important components of your engine, like your cam shaft or crank bearings. This lack of adequate lubrication can quickly lead to bearing damage, again requiring an engine rebuild.

Allowing engine oil to leak anywhere can quickly lower engine oil levels which will also reduce lubrication in your engine and cause the same damage to bearings and camshafts. Lastly, allowing gases to leak out of your combustion chamber can cause abnormally high pressures in your cooling system and problems in the metal around the leak. Leaking coolant and combustion gases can cause high temperature gradients leading to erosion of the leak area and possible cracking.

The Verdict: Can You Drive With a Cracked Head Gasket?

For all these reasons, we don’t recommend driving with a blown head gasket.  The good news is there is a quick and easy way to seal your blown head gasket, prevent future leaks, and keep your car on the road.  BlueDevil Pour-N-Go Head Gasket Sealer is a specially formulated sealing agent you can add to your vehicle’s radiator that will seal a head gasket leak as you drive. BlueDevil Pour-N-Go doesn’t take any tools to install and will quickly and easily seal your head gasket leak.

    Can I use the pour and go head gasket sealer after I already used the pour and go radiator and block sealer? The radiator and block sealer seemed to help so far but I noticed coolant leak under the expansion tank cap- I’m concerned it may be exhaust gases due to head gasket

    • BlueDevil Pro on December 6, 2016 at 12:12 pm

      Charles-

      We recommend flushing the cooling system prior to adding the BlueDevil Pour-N-Go Head Gasket Sealer. A clean, free-flowing system, will give the product the best chance of circulating and sealing properly.
      If you are getting combustion/exhaust gases blowing into the cooling system and creating pressure then we recommend applying BlueDevil Head Gasket Sealer.  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.

      Thank you!

        Hi,
        Ibhave a 2006 ,Chevy equinox diagnosed with a blown head gasket with an estimated cost of $2,300 to repair. Also engine oil and coolant leaked everywhere . Can I forgo this expensive job and pour the blue devil to seal it up?

        • BlueDevil Pro on February 28, 2018 at 8:30 am

          Beverly-

          Thank you for asking about your Chevy Equinox. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. Unfortunately, we do not manufacture a product intended to stop oil leaks from the head gasket, if that is where the oil leak is occurring from. 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!

        Leave the spark plug out while you run it?

        • BlueDevil Pro on April 9, 2018 at 9:31 am

          Steve-

          Leaving the spark plug out from the affected cylinder would reduce the amount of pressure (from combustion/exhaust gases blowing into the cooling system) building up and allow the product to circulate and seal properly.

        This sounds like my problem. Pretty sure it’s the head gasket. The Car will idol 50 min and not lose more than a quart. Unfortunately I can’t get to the plugs. It’s a 2003 Buick Century and just to get to the back 3 plugs require moving the whole engine back. I’m not prepared or equipt to do that. Should I use your product anyway ?

        • BlueDevil Pro on June 28, 2018 at 9:53 am

          Shane-

          You may still use the product without removing the spark plug from the affected cylinder. However, if there is a build up of pressure in the system from combustion/exhaust gases getting into the cooling system, the circulation of water/coolant may be fairly restricted, and the product may have a tough time circulating properly to get to the leak point to be able to seal. Feel free to contact our technical support line at 888-863-0426 with any other questions.

            Thank you for asking about your Honda Civic. Unfortunately, it sounds like the vehicle may be overheating a little too quickly for the BlueDevil Head Gasket Sealer to be successful. 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. A hard part repair may be your best option.

      • Minnie on June 30, 2018 at 3:55 pm

        My son’s 1993 town car quit on him and won’t start. He said it ran hot and poured antifreeze in the reservoir but noticed it was still empty. He was told to check the oil stick, but he couldn’t tell what to look for. He poured more coolant and didn’t see no leaks, and still it’s empty. Can his head gasket be blown? Is the car worth repairs?

        • BlueDevil Pro on July 2, 2018 at 9:18 am

          Minnie-

          Thank you for asking about your Son’s Lincoln Town Car. 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!

          If the coolant isn’t getn in the oil an you dnt see wher the coolant is leaking frm replace the radiator cap the pressure spring on cap is weak an you’re losing coolant as you’re driving it an is y you’re not seeing any coolant

      • Jg on August 2, 2018 at 3:07 pm

        While the vehicle is running, what would ‘ve the sign it’s getting better, less smoke, no smoke?

        • BlueDevil Pro on August 3, 2018 at 8:32 am

          Jg-

          You might look for the white smoke to reduce during the 50 minute idle, however, it can take several hours for the exhaust system to completely clear itself out of any water vapor or moisture, so it may not stop right away. A good sign would be if vehicle is able to maintain idle for the full 50 minutes, without overheating or stalling out.

        Hi, I drive a 2006 Toyota camry and it overheats any time I go above 2000rpms and the a.c. is on but cools down when I reduce speed driving below the 2000rpm Mark and also turning of the a.c. is it possible i have a blown gasket head or I should look for other causes?

        • BlueDevil Pro on June 4, 2019 at 8:42 am

          Mobolaji-

          Thank you for asking about your Toyota Camry. Just because the vehicle overheats does not necessarily mean you have a blown head gasket. A vehicle can overheat for a number of different reasons. Unless you are seeing water/coolant getting back into the engine oil or white smoke/steam coming from the exhaust pipe, it would be difficult to say whether it was head gasket related or not, especially without further diagnosis. Your best place to start may be to check the thermostat to make sure it is opening at the proper temperature and to perform a cooling system flush to remove any deposits restricting or impeding flow.

          Thank you!

          Has the vehicle been diagnosed as having a blown head gasket? If so, we recommend using the BlueDevil Pour-N-Go Head Gasket Sealer for your Honda Civic. The Pour-N-Go Head Gasket Sealer is an easy, do it yourself version of our 32 oz. Head Gasket Sealer (yellow label). As long as the vehicle will maintain idle for a full 50 minutes without overheating or stalling out, and you are not losing more than about a quart of water/coolant during that 50 minute run, you would be a good candidate for the product.

          Thank you!

        My brother has a 2004 audi a4 1.6 liter with a turbo and coolant light stayed on and the reservoir bubbles over when opened. He took it to a shop and it was diagnosed with a blown head gasket and would cost 4500$ to fix. Do you think the sealer would help and seal the gasket ?

        • BlueDevil Pro on July 17, 2018 at 3:53 pm

          Chase-

          Thank you for asking about your Brother’s Audi A4. It is possible that the vehicle is 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!

    Ive had my car for about two months. I just found out about a blown head gasket about two weeks ago. I have not driven long distances but I have driven. The car was leaking coolant and needed to be filled with oil as well, all of which was done two weeks ago. Could something worse have happened in the past two weeks?

    I have a 2005 yukon that i believe has a blown head gasket. It smokes a little white smoke and no obvious leaks. We can drive it around all day and it uses about half a gallon of water. Can i use your prosuct and be safe to drive this on vacation approx 2000 miles round trip

    • BlueDevil Pro on March 22, 2017 at 10:31 am

      Harris-

      Thank you for asking about your GMC Yukon. Based on your description, we recommend using the BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/). Once the product seals, it would be a permanent seal. You can feel safe driving the vehicle once the repair is achieved.

          Thank you for asking about your BMW X5. The BlueDevil Head Gasket Sealer would not be appropriate to use in a case where you are not losing water/coolant, as the product is intended to seal water/coolant leaks.

      Thank you for asking about your Honda Accord. As long as the vehicle can maintain idle for a full 50 minutes, without overheating or stalling out, 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.

    I have a 1999 Olds 88..My vehicles temp gauge went into the danger are so I stopped and the antifreeze resevoir was empty..So I filled it to the hot line drove about 4 miles to get home..When I got there it was empty again…So I repeated what I did the first time drove it for about 15 minutes. Came home empty again..I have no leaks nothing on the ground so I dont know where all this liquid went..I tried one more time and this time put plain water in resevoir drove it and temp came down..Got home water gone…So I let it sit for a hour remover radiator cap could see no fluid..When I trie to start it it ran really rough and acted like it was going to backfire so I shut it off…

    • BlueDevil Pro on April 20, 2017 at 4:18 pm

      Thank you for asking about your Oldsmobile 88. Based on your description, it sounds like you may be getting water/coolant into the cylinders, causing the really rough start you’ve experienced. Unfortunately, it sounds like you are losing water/coolant a little too quickly for the BlueDevil Head Gasket to be affective. In order to get the benefit of using the product, 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. A hard part repair may be your best option.

Have been told by 2 separate mechanics – 1 a Subaru Tech, it’s a combustion problem/internal engine and I should start looking for another vehicle. Repairs would cost $5,000 or more. Mileage is 172,000. Is Blue Devil Gasket Sealer wise to use for a 3.0L 6cyl Subaru LL Bean Wagon?

    My Honda civic 2004 runs perfectly. But it subjected to longet trips it gets hit and over heats. I would need to make it cool down and add coolant.
    It would run okay for another 1000km
    But I will need to add coolant again
    Does this frequent coolant addition mean a blown head gasket
    I remember one morning I found coolant leaking after i got to work. I just left it and came back to it at the end if the day…ever since its bn fine.
    What do you recommend.. I need the car running for at least 3more months

    • BlueDevil Pro on July 18, 2017 at 9:22 am

      Julie-

      BlueDevil should not be added to a coolant reservoir/overflow tank. If your vehicle only has a reservoir/overflow rather than a radiator cap, instead of pouring it 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). The speed of the pour will not make any difference as the engine will be off. Once it has been added, reconnect the hose and start the idle from that point.

    My 2004 Jeep Grand Cherokee (129K) recently had a little bit of a rough start and then the check engine light came on. The mechanic said the code was for #6 coil. He replaced the coil and spark plug. After 2 days the check engine light came back on. The mechanic performed some tests and said I need to replace the engine ($4,000.). He said that some antifreeze is splashing onto the coil when I turn the car on and that the car would run rough until the antifreeze burned off.

    The car starts and runs fine but I think I am on borrowed time.

    Will this product help here?

Its full of water now but I cant see how much water it uses after the test so after running it idle for 50 minutes Im going to have to pour a quart of water back in to measure. First of all after the 50 minute mark Im going to have to wait for an hour until it cools off but will the measurement be effected by then? If so how should I measure the amount of water being used up as soon as the 50 minute mark is reached?

      Thank you for asking about your Chevy Silverado. It is not a requirement to test how much water you are losing prior to using the BlueDevil Head Gasket Sealer. Customers who are seeing the greatest benefit of using the product have vehicles that maintain idle for a full 50 minutes, without overheating, and are not losing more than about a quart of water/coolant during that 50 minutes. It would be tough in most cases to measure exactly how much water you are losing. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      The BlueDevil Head Gasket Sealer does not contain any solid or particulate matter, so it will not clog or harm your engine or radiator.

    my 17 year old son has a 1996 Volvo 850, it had a coolant leak which we thought was a water pump issue. This past thursday we replace the water pump, timing belt, and drive belt. In flushing the cooling system it appeared to be fine and even test driving the car by the mechanic and my son and I it seemed to be fixed so the next day he drove it to school. When he came home thick white smoke was coming out of the exhaust, his check engine light was blinking, and when I checked under the hood he had absolutely no coolant left. So today I took it back to the shop that replaced his spark plugs and wire and had them check his car and they told me that the check engine code brought up a “cylinder 3 misfire” and after further diagnosis, it was confirmed he had a blown head gasket. I am on the fence about selling it as I don’t think I will get remotely close to the money I put into it and I need this car to either sell for a relatively good profit enough to get him another car or be fixed to last my son until the end of the school year when he graduates

I was able to stop at a express mechanic shop on the way. The antifreeze reservoir and radiator were empty. Mechanic said it was fault of a bad water pump,. We filled radiator with water,also did some test on top of radiator opening with some tester that showed water turning green and bubbles.

    I just bought a 1996 Cadillac Deville to help my brother-in-law out since he just moved to the US from Venezuela. Unbeknownst to me the car has just started showing signs of a blown gasket, although secondary’s are minor at this point. Will this product work on a Northstar engine? Only need the car to work for 3-6 months until my B-I-L gets on his feet.

    I know I have a blown head gasket on my 97 Ford F-150 with a 4.6 The oil dipstick is over full with brown motor oil. And empty radiator over flow. Container my question is should I warm engine. And drain and add new oil and filter before adding. Your head gasket repair. It also has a skip due to a bad spark plug .

      Donald-

      Thank you for asking about your Ford F-150. Based on your description, we recommend changing the oil before and after the BlueDevil process, however, the engine should be cold before adding the product. It is also 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!

    I am avout to get a 95 Nissan pickup with a blown head gasket. It is a 2.4L inline 4 with 244000 miles. The truck can run for only 30 minutes before it starts getting how and nees to add water. My question is will blue devil head gasket sealant work well enough to let me drive this truck as a daily driver? Also, what if the head is cracked or warped a little?

    • BlueDevil Pro on September 7, 2017 at 10:59 am

      Mark-

      Thank you for asking about your potential Nissan pickup. The BlueDevil Head Gasket Sealer does treat warped/cracked heads, however, in order to get the benefit of using the product, the vehicle needs 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, it does not seem the vehicle would idle long enough for proper results.

      Thank you!

    Hi I drive a Nissan wingroad wagon with a QG 15 engine I started noticing my radiator reservoir was been bubbling after driving, some one told me that’s a sign that my head gasket is blown, but not losing any coolant, and no water in the oil, are these sign of a blown gasket?

    I have a 2008 Nissan Armada and we’ve replaced the radiator 2x. We now have white smoke and water leaking from the tailpipe after putting in brand new radiator. All signs say blown head gasket. Will this stuff work?

    • BlueDevil Pro on October 24, 2017 at 10:56 am

      Hollie-

      Thank you for asking about your Nissan Armada. As long as the vehicle will maintain idle for a full 50 minutes, without overheating or stalling out, 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.

    I bought a BMW 325i and I drive it around for about a year with no problems. Now it seems to be overheating a lot. I have already replaced the radiator, water pump, and the thermostat. My car still overheats and I don’t lose coolant. I bled the system pretty well… Now I’m noticing a white smoke coming from the exhaust. I know well assume this is a blown head gasket. Would this product work?

    • BlueDevil Pro on November 3, 2017 at 10:25 am

      Christa-

      Thank you for asking about your BMW 325i. White smoke coming from the exhaust pipe is a tell-tale sign of a blown head gasket, and would also indicate that you are losing water/coolant. 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.

    I have a 2005 Nissan Altima 2.5 engine. Can I still use this product if my oil cap has milky oil on it? & if so do I have to change the Engine oil afterwards?

    • BlueDevil Pro on November 10, 2017 at 10:26 am

      Danny-

      Thank you for asking about your Nissan Altima. Yes, water/coolant getting into the oil is a tell-tale sign of a blown head gasket and would be worth treating with the BlueDevil Head Gasket Sealer. We recommend changing the oil before and after the process. Feel free to contact our technical support line at 888-863-0426 with any other questions.

    I have a 2008 Cadillac DYS At first we thought it may be a water pump or thermostat but all are replaced and mechanic says they are good. The car I can drive for 20 something minute then starts running hot. Coolant coming from overflow pressure release from the overflow reservoir bottle after 10 minutes of driving. No other places show coolant. Reservoir usually empty after cooling down. Could this product help because I believe the only thing left is a head gasket or cracked head.

    Possibly a blown head gasket 1997 Ford ranger super cab 3.0 engine 122K on it. Had a plume of white smoke ran it less than 1 mile to get it home. Engine won’t turn over didn’t overheat

    A few folks told me to drop the oil pan push up on rods and hopefully that’ll aleviate the water pressure. I’m wondering if I’d be a candidate for this product or if there’s something else I can do without pulling the engine

      Steve-

      Thank you for asking about your Ford Ranger. In order to get the benefit of using the product, the vehicle would need to be able to idle a full 50 minutes without overheating or stalling out. If the vehicle is unable to start, unfortunately, it would not be a good candidate for the product. A hard part repair may be your best option.

    I have a 2005 Buick Terraza, it’s heater was not working and We were told to get coolant flush done. After we did that the heater came in for a day and hen stopped and overheating again. Now the mechanic recommended to change the thermostat, so we did that. After the thermostat was changed and right after that without driving away it started giving out thick white smoke from tailpipe and it is overheating.

    The mechanic says there are no coolant leaks outside the car and the head gasket is blown. He is recommending to replace the engine.

    Any options for me before I do that?

    Will this sealant work?
    If I use this sealant is it as easy as pouring into the radiator or I will have to remove the spark plugs?

    Please help

    My son has a 2002 Subaru Forester that just started overheating. There’s no white smoke, and the oil looks completely normal. The coolant, however, looks like hamburger grease, not the chocolate milk I keep reading about. (Everything’s a food reference.) Several people have advised us that its a blown head gasket-without actually looking at it. Considering using the BDP sealant, The engine splash shied is bolt-rusted on, so flushing is a bit of a problem. May have to try EZ outs and flush prior to using sealant, or can it be added as is? Thanks.
