Can you Drive with a Blown Head Gasket?

 

can you drive with a blown head gasketIf you’re asking yourself “can you drive with a blown head gasket”, then you either have a blown head gasket already or you drive a vehicle that is known for blowing head gaskets.  If you’re driving a vehicle that is known for blowing head gaskets, you may be able to do a few things to prevent that from happening to you.  For more information, check out our article about preventing a blown head gasket.

If you’ve already got a blown head gasket, you need to understand what is actually going on in your motor to understand why it’s a bad idea to drive with a blown head gasket.  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 and to keep coolant and oil out of the combustion chamber so they don’t foul the ignition process and so your vehicle doesn’t 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 the oil and allow engine oil to get in all of these places as well.  The real 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.

Allow 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 which can lower compression and require and engine rebuild.

Next, you could end up with coolant in your engine oil either by seeping past your piston rings or due to a direct leak from a coolant passage to an oil passage.  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.

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 and keep your car on the road.  BlueDevil Pour-N-Go 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.

  1. 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

    1. 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.

      1. 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?

        1. 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!

        1. 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.

          Thank you!

          -BDP

      2. 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 ?

        1. 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.

      3. 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?

        1. 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.

        1. 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.

    2. I have a BMW X5 2006 my truck has not ran hot yet but I do get the white smoke from the tail pipes and some time it does not want to start after I drove it for a while but when I turn the key and keep my foot on the gas it start right up

      1. Viola-

        Thank you for asking about your BMW X5. Based on your description, it is quite possible you are dealing with a blown head gasket, with white smoke coming from the tail pipe and water/coolant possibly making it’s way into the cylinders. If that is the case, we recommend using the BlueDevil Head Gasket Sealer (https://store.gobdp.com/head-gasket-sealer-38386/). You may want to check your spark plugs and have any replaced that seem to be deteriorated our fouled out.

    3. I was told I have a blown head gasket I can drive the car for about 15 minutes before it over heats I stopped driving the car once I found out about the head gasket some street mechanic told me he would do this process with your product for cheap is this process worth trying or just save the money n replace the gasket I’m Leary

      1. Terrikim-

        The BlueDevil Head Gasket Sealer comes with a money-back guarantee. If it is unable to seal the leak for whatever reason, you would be able to contact us for a refund. That being said, 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, and you should not be losing more than about a quart of water/coolant during that 50 minute run. Feel free to contact our technical support line at 888-863-0426 with any other questions.

        Thank you!

        -BDP

      1. Ivan-

        Yes, the BlueDevil Head Gasket Sealer would seal a leaking block as well. As long as you are not losing water/coolant too quickly, you should be able to see some good results.

        Thank you!

    4. Hi I have a 2012 Chevy Cruze and recently I noticed that it has been overheating and it’s not leaking anywhere how do I know if its a blown head gasket.

      1. Jenny-

        Thank you for asking about your Chevy Cruze. Unfortunately, a vehicle can overheat for a number of different reasons. Unless you are seeing water/coolant getting into the engine oil or white smoke from the exhaust, it would be difficult to say whether or not it is head gasket related. Your best bet may be to bring the vehicle to a certified ASE mechanic for a proper diagnosis.

        Thank you!

      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 (http://store.gobdp.com/head-gasket-sealer-38386/).

      1. 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 ?

        1. Chase-

          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. Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

  6. 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…

    1. Janice-

      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.

  7. I own a 2002 Subaru Outback LL Bean (3.0L 6cyl) and am adding coolant every week, about a cup or more. 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?

  12. 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

    1. Ak-

      Thank you for asking about your Honda Civic. A loss of coolant does not necessarily indicate a blown head gasket. Based on your description, we recommend taking the vehicle to a certified ASE mechanic for a proper diagnosis as to why you are losing coolant.

    1. 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.

      Thank you!

  16. 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?

    1. Adrian-

      Thank you for asking about your Jeep Grand Cherokee. It sounds like the vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. In this case we recommend applying BlueDevil Head Gasket Sealer (http://store.gobdp.com/head-gasket-sealer-38386/). 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 lowest 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.

  17. I have a chevy silverdo 94 they told me it has a cracked head gasket. 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?

    1. Abe-

      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.

    1. Marrie-

      You should use BlueDevil Radiator Flush prior to installing BlueDevil Head Gasket Sealer. When we refer to allowing the vehicle to idle for 50 minutes we mean the vehicle should remain stationary with the engine running for 50 minutes.

      In order to get the benefit of 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. Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

      Thank you!

  21. I have a 1987 delta88 I changed the oil and noticed bubbles in the oil.will blue devil head gasket sealer work for this vehicle.

    1. James-

      Thank you for asking about your Oldsmobile Delta. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. Unfortunately, we do not manufacture a product for the type of symptoms you have described. We recommend bringing the vehicle to a certified ASE mechanic for a proper diagnosis and possible part replacement.

      Thank you!

  22. If your product is able to seal a cracked head, how does it not seal up the tiny lines running through the radiator?

    1. Shauna-

      The BlueDevil Head Gasket Sealer does not contain any solid or particulate matter, so it will not clog or harm your engine or radiator. The product is attracted to air flow, and works by looking for the temperature differentials in the system and then reacts with heat to form a chemical weld. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

  23. 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

    1. Tammie-

      Thank you for asking about your Son’s Volvo 850. Based on your description, It sounds like the vehicle is getting combustion/exhaust gases blowing into the cooling system and creating pressure. 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. Be sure to follow the guidelines for the proper amount to use based on the size of your cooling system.

      Thank you!

  24. Hi I have 96 Honda accord that keeps giving me problems I knew I had a head gasket prob now when I stop at a light or stop sign its sputters and shakes even when I accelerate and white smoke does come from oil cap too…

    1. Jose-

      Thank you for asking about your Honda Accord. Have you noticed a loss of water/coolant? Based on your description, it is possible you are getting water/coolant back into the cylinders, causing it to sputter and shake. Water also may be getting into your oil. Please contact our technical support line at 888-863-0426 so that we can get a better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

  25. I live in Tampa, Fl and have a 1997 Dodge Van Ram 1500, 5.2L motor 318, 8 cylinders. Yesterday during a working day it overheated badly with fumes coming out of the hood. 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. He said I have a blown head gasket and need to replace the engine. Will the Blue Head Gasket Sealer work ? I am planning on taking the van to a mechanic for a more accurate opinion and obviously decision. Thank you for your input.

    1. Orlando-

      Thank you for asking about your Dodge Ram 1500. 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.

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.

  27. 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 .

    1. 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.

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?

    1. 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.

  31. 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?

    1. 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.

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.

  36. 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?

  37. 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.

      Thank you for asking about your Son’s Subaru Forester. Have you noticed a loss of water/coolant? Based on your description, we’d recommend having the vehicle diagnosed by a certified ASE mechanic.

  43. I have a 2001 VW Passat, I have white smoke blow out my exhaust only when I start up the vehicle I’m not really loosing any coolant that I can tell but I do have a little milky mess in my oil. Is this a blown head gasket and which product would be best for to help resolve this?

    1. Nate-

      Thank you for asking about your Volkswagen Passat. Unfortunately, white smoke from the exhaust pipe and milky oil are two tell-tale signs of a blown head gasket. You may use either of the Head Gasket Sealers that we manufacture. The “Pour N Go” (16 oz./white label) 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” (32 oz./yellow label) 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. With the use of either product, be sure to follow the guidelines for the proper amount to use. Based on your cooling capacity, you will be applying about 16 ounces either way.

  44. If I have one cylinder completely dead, it has been diagnosed as blown head gasket, and I have driven that way for several miles, and then I have poured in the head gasket seal, idled the vehicle, let it cool down, will I need to do anything else for the dead cylinder to make it run again, like drain and replace fluids?, or normally would the gasket sealant be all that’s needed? The whole time I was idling after pouring in the head gasket seal, the dead cylinder did not fire at all. I am letting the engine cool down now.

    1. Keith-

      You may want to do a compresssion test to verify that the dead cylcinder is now reading at the proper measurement.

  47. My 96 Toyota 4 Runner 3.4 L is known for blown head gaskets. Yesterday, we got stuck on the highway when the engine overheated and the radiator cracked and blew out all the coolant.
    The coolant level was nil
    Periodically, wed hear a click, and steam would spew out of a 9″ crack in the radiator header.
    There was no smoke from the tailpipe, but the steam left an oily residue
    Once we poured almost 2 gallons of water into the radiator, we were able to get the car 4 miles home, with no overheating.
    When idling, there were no visible bubbles in the coolant.
    When the car was revved, a Lot of bubbles came out through the radiator filler hole.
    Am I experiencing a blown head gasket, or could this be a combination problem of a sticky thermostat and the crack in the radiator?

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 minute run, you would be a great candidate for the BlueDevil Head Gasket Sealer (https://store.gobdp.com/head-gasket-sealer-38386/). Feel free to contact our technical support line at 888-863-0426 with any questions.

      Thank you!

  51. I have a 2002 Oldsmobile silhouette van over heated fixed hose that sprayed coolant now van still over heats and was told blew gasket can I use blue devil and be able to drive

    1. Mike-

      Thank you for asking about your Oldsmobile Silhouette. 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!

  52. I have noticed white smoke coming from my exhaust from time to time, Maybe one out of every 5 times I start it. It stops after a minute or 2 I added a block seal and antifreeze even though it did not need it. The antifreeze was in great shape I still see white smoke from time to time. What could it be a?

  53. I have an 04 f_350 6l diesel. There is oil in the rad over flow and you can see that it bubbles when the engine is hot. Still runs. Has white smoke at start up. Mechanic say it is possibly a blown head gasket. I have fuel in the oil. Will your product help. Will i have to flush the rad. Need to make a trip of 1500 km to get home, so i can deal with it when i get back. Can your product get me back home?

    1. David-

      Thank you for asking about your Ford F-350 Diesel. Unfortunately, we do not manufacture a product intended to stop oil from getting into the radiator, or fuel from getting into the oil. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks. A hard part repair may be your best option.

  55. Hello I have a 2003 Lincoln towncar executive my car made a loud sound and now white smoke is coming from my tail pipe could that be my head gasket and will your product work for my car

    1. James-

      Thank you for asking about your Lincoln Town Car. Unfortunately, white smoke coming from the exhaust pipe is a tell-tale sign of a blown head gasket. 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 minute run, you would be a great candidate for the product.

  56. I have a Nissan Altima 06 , 2.5 cylinder. I tried to start my car and it cranks but won’t start up due to a blown head gasket and was told it was filled with water. Will using this product solve the problem?

    1. Latavia-

      Thank you for asking about your Nissan Altima. Unfortunately, the vehicle would need to start and idle for a full 50 minutes in order to get the benefit of using the product. Is it not starting because water/coolant is getting back into the cylinders?

  58. I have a Subaru Legacy Outback that had just started having white smoke come out the tailpipe, it was not overheating and my oil looked fine. My car runs perfectly now that I’ve use the poor in but my question is how long will this last? Is my car going to eventually need to go to a shop and have a mechanic work on it to resolve the head gasket problem once and for all?

    1. Heather-

      Thank you for asking about your Subaru Legacy Outback. We are glad to hear the BlueDevil Pour-N-Go Head Gasket Sealer was able to seal your leak. Once the product seals, it would be a permanent seal, so you should be good to go at this point! Feel free to contact our technical support line at 888-863-0426 with any other questions.

  59. My 2009 Dodge Caliber had a hose leak I didn’t know about and overheated on a long drive about 3 months ago. It drove fine for two months after that and overheated again on second long drive when the leak was discovered and repaired and the car drove fine another month after that. Then it started having loud engine sounds and a mechanic checked it and diagnosed the car as having a cracked engine block. The repair costs were estimated to be $2000 plus. I can’t afford that and noticed the engine light never comes on, and I haven’t noticed the telltale white exhaust smoke, and the car starts and runs fine without engine overheating lights coming on, but I’ve stopped driving it because it worries me that I’ll cause worse damages because of the loud engine noise. Would your product be able to stop the noise problem and prevent me from having an expensive engine repair bill?

    1. Debbie-

      Thank you for asking about your Dodge Caliber. The BlueDevil Head Gasket Sealer is only intended for water/coolant leaks.

  60. I just developed a small coolant leak and already tried to use K-seal. It didn’t work. What is happening is upon start up and warm-up, the car leaks a small amount of fluid from the top of the radiator, like it is blown out. I replaced the radiator cap and see no visible leaks in the hose. A mechanic told me the only thing that could cause that type of pressure blow-out would be a head gasket issue. I don’t understand why it doenws’t blow out in the overflow tank overflow. The vehicle is a 2001 Honda Passport 6 cylinder. Do you think it sounds like a blown head gasket? Otherwise the car is running great. It is not overheating after hours of test driving, just leaking a little coolant now and then. bryan

  61. I have a 2004 Ford Escape and while doing a routine once over I notice that my coolant is milky white in the resovior. I haven’t had any overheating problems and the vehicle runs perfectly. I checked my oil and it’s at the level it should be and looks perfect. I would assume its a slow head gasket leak. Would Pour and Go be a good or is it too late for that?

      Thank you for asking about your Ford Escape. Based on your description, it does not sound like you have any of the tell-tale signs of a blown head gasket.

  62. Hello…
    If a head gasket leak, how can I determine the exact cylinder?
    The car in question passed smog 4 months ago, sat and then developed white smoke problems.
    Is this possible?
    Blow the gasket without overheating?
    I am curious to hear, as I am considering buying this car.

    1. Douglas-

      A vehicle can have a blown head gasket without having water/coolant getting into a cylinder, however, the engine would have had to of overheated at some point in order for the head gasket to be blown.

  64. Hello-
    I have a 2004 Nissan Sentra. I recently had the hose replaced as it busted on the freeway. A few days later I saw it was leaking. My mechanic said it’s a head gasket and repairs will run from 800 – 1300, depending on how bad it is. I’m still driving it as I don’t have any other means but it does run hot every so often. I check the coolant before i turn on the car and go but was wondering if your product will eliminate the repair altogether or is it just a temporary fix.
    Thank you.

    1. Leslie-

      Thank you for asking about your Nissan Sentra. Once the BlueDevil Head Gasket Sealer creates a seal, it would be a permanent seal.

  65. Hello,
    We have a 2004 Range Rover that we used the head gasket repair solution in. There were no signs of the typical head gasket issues other than an overheated engine. The thermostat was replaced and the solution was used to try and address the overheating. The engine sounds great and has sounded great throughout the process but the overheating continues. The fan has also been checked. Any suggestions?

  66. We are sure we have a blown head gasket and were interested in BlueDevil pour n go. But as I understand it the stuff is a temp fix. That if I go later to replace the actual gasket that I’ll have issues removing it because of the sealant. Is that true? I don’t want to make more trouble for myself later or mess up the truck even more. Please help.

    1. Andrea-

      The BlueDevil Pour-N-Go Head Gasket Sealer would create a permanent seal. It would not be considered temporary. If you were going to replace the head gaskets in the future, using the product would not hinder that in anyway.

  67. 96 Caprice classic coolant tank has over flowed and steamed twice in one day no over heating no white smoke no exhaust fumes in the coolant no milky oil tranny fluid is good too no external leaks either could this still be a blown head gasket?

    1. Sheri-

      Thank you for asking about your Chevy Caprice. Based on your description, it does not necessarily sound like a blown head gasket. It does sound like the system is building up pressure, which could be due to a faulty water pump, faulty thermostat or even a potential clog in the system. We recommend checking the thermostat and water pump first to eliminate them as being the culprit for the overflowing coolant and having the system flushed to get rid of any debris or jellied antifreeze that may be restricting flow. If they are fine, and you are still having the same issue after having the system flushed, you may want to have a block-dye test performed to check for combustion/exhaust gases entering the cooling system.

      Thank you!

  68. Hello! Wondering if this is a product for my issue. I have a 2002 Hyundai Elantra, that I don’t want to invest too much more money in. It’s recently been overheating, though doesn’t have any external leaks. Our shop thinks it’s a blown head gasket (sadly we replaced it just 2 to 3 years ago!), which is causing increasing pressures, resulting in the coolant burning, etc. Thoughts?

  71. I have a 1989 350 5.7 Chevy. I recently finished rebuilding my and this is going on two years since it has been finished. During the past year I only drove backroads and went only about 15-20 minutes away and never took the interstate. Now i am in college and in order to get there i have to take the interstate. My truck hasn’t been used to driving 70-75 on a daily basis and more recently the past week or so it has been running a lot hotter than normal. I checked the Anti-freeze and i was a little low but not by much at all but i did pour in a little more to be on the safe side. The next day it was still running hot like it was before so i checked the oil and i was low on oil by about a quart so i put some more oil in like i do every month or so like normal because my truck eats the oil. And again still running hot now a week later and i checked for leaks and i don’t see any leaks. Does it sound like i have a blown head to you? And if so what should i do?

    1. Alaina-

      Thank you for asking about your Chevy. Based on your description, it would be tough to say whether or not this is head gasket related, although it is very possible. Are you seeing any smoke from the antifreeze or oil burning off? Have you noticed any water in the oil or oil in the radiator? Without seeing either leaking externally, it could be that you are losing both internally. Have you noticed any kind of bubbling or boiling over in the cooling system or have you been getting a misfire code? 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.
