Head Gasket Repair Cost

head gasket repair costHead gasket repair costs can have a surprising range based on the mechanics you are working with and the make and model car you have.  Any head gasket repair job is going to be relatively expensive because of the required labor to get to your head gasket.

The head gasket is basically in the middle of your engine so you have to take off just about everything on top of your engine to get to the gasket.  If you have an inline 4 cylinder, or incline 6 cylinder engine, this job may not end up being so difficult.  Removing the head on this type of engine includes simply draining your engine fluids, removing the intake and exhaust manifold, the cooling hoses the timing chain or belt and maybe a few accessories to make more room to work.

If you have a V6, V8 or boxer engine, getting to the head gasket can be significantly more complicated.  In these type engines, you actually have 2 head gaskets, one on each side of the engine.  If you’re replacing the head gasket on your vehicle you should always replace both of them to make sure your engine stays balanced.  Also, since you already have the majority of the engine taken apart to replace once gasket, it is cost effective to do the other one at the same time.  With a “V” style engine or boxer engine, head gasket replacement costs can be 2 to 3 times the amount simply due to the extra labor associated with getting to the head which is more inaccessible on these vehicles.

The other thing that can significantly increase your head gasket repair cost is what other damage was caused when the head gasket started leaking.  The drastic temperature changes along with the pressure of combustion leaking into different areas of the engine can cause problems with your cooling system and cause permanent damage to your engine block or cylinder heads.  Since the head gasket has to retain the high temperatures and pressures of combustion, it needs to make a very tight seal between the cylinder head and engine block.  If the surface of the cylinder head and engine block aren’t perfectly flat, then it can be difficult for the head gasket to make a good seal.

This is where costs can really add up for head gasket repair.  If you cylinder heads are warped, cracked or pitted it can take a significant amount of machine work to get things back to where they need to be.  Even worse, if your engine block isn’t flat or has been damaged, it will need to be removed and machined as well.  Since the shops that will do that kind of work are usually specialty shops the prices can be extremely high.  If you decide not to check your block or head for damage you also can end up with a leak even in your brand new head gasket.

There is a way you can avoid all the labor of taking apart your engine and the expensive inspection of engine parts for damage.  BlueDevil Pour-N-Go Head Gasket Sealer is a chemical sealing agent that you can add to your engine coolant to seal the leaks in your current head gasket.  BlueDevil Pour-N-Go Head Gasket Sealer is a non-particulate sealant that can seal the leak in your head gasket without removing any equipment from your motor.  BlueDevil Pour-N-Go Head Gasket Sealer can even seal a leak if your block or head is warped.

    1. Ian-

      Your vehicle stalling out and overheating does not necessarily indicate that you have a blown head gasket, however, it is a possible symptom of that. Have you had the vehicle diagnosed? Are you noticing a loss of water/coolant? 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!


  2. I have a 96 Honda Civic And I believe that my head gasget is blown due to over heating and because I’m a woman and did not know. My car was smoking so I pulled into a gas station and I put water in the radiator without coolant not to mention water was cold but it brought down the temperature until driving further it smoked up and over heated I pulled over to the side had help off course and coolant was put in. Now it did bring the temp down but driving it home it was starting to over heat. Are there any options of a way that I can fix the predicament that I am in, or am I totally SOL at the moment and need to get a new car? By the way this happened yesterday any advice would help. Thank You

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

      Thank you!


  3. I have a 1995 Honda lx. It overheated and stalled on the highway coming to a complete stop. I got to the side snd openned the hood. No dmokd or steam. What does that mean?

    1. The radiator was replaced and now it still is running hit. Mechanic says maybe the gadget is blow. How likely is it the engine block is cracked?

      1. S Holmes-

        Please contact our tech support team at 888-863-0426. We would be happy to discuss the symptoms that you have seen with the vehicle to help diagnose the problem.

        Thank you!


  4. I have a 08 honda oddassy and it started to over heat. I replaced the thermostat, but still overheating. I took it to a garage and they diagnosed it saying it was the water pump and timing belt. They replaced that and the day I brought it home on a Friday, it started to leak antifreeze took it back Saturday for them to check it. They call Monday and they said they think there was a air pocket in the radiator and said they fixed it. When I got there to pick it up it looked like it was leaking antifreeze again but they said it was not from my van. When I started it, it was shaking and got worse when I turned the wheel. Then started to blow white smoke coming from the tail pipe. They said that I blew a head gasket when I pulled out. Shouldn’t they have caught this when they went over everything the first time?

      Thank you for asking about your Honda Odyssey. Unfortunately, a vehicle can overheat for a number of different reasons. When you originally brought the vehicle in, after replacing the thermostat, replacing the water pump would have been the next logical component to replace. Unless the garage was seeing white smoke coming from the tail pipe or water/coolant mixing with the engine oil, it would have been difficult to diagnose it as a blown head gasket at that point. From the sounds of it, you may have combustion/exhaust gases blowing into the cooling system, which would give you the same symptoms as an air pocket in the system.
      As long as the vehicle can 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 good candidate for the BlueDevil Head Gasket Sealer. Feel free to contact our technical support line at 888-863-0426 with any other questions.

      Thank you!
