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.

      Thank you!

  2. I’m wanting to buy a car and drive it for two hours, from the bought destination to home. The car has a blown head gasket. Engine is a 1.6 16v, I’m thinking of getting it fixed when I get it home. Will your product do this task for me?

      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/). Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!

  3. 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?

    1. LeEisha-

  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.

      Thank you!
