And what does it do? What Causes a Blown Head Gasket? A head gasket, like other mechanical systems, usually suffers and fails at its weakest point. The weakest points are the areas between cylinders where the material is thin, the subtle variations in the thickness of the metal, and the insertion points where the bolts affix the head to the block.
These weak points are exacerbated in the design stages, during factory or aftermarket installation, or because of the operating conditions in the vehicle. The situation is serious as replacing the head gasket is labor-intensive and expensive. It is also serious because other operating conditions may have caused the problem, which may be time-consuming and expensive to repair as well. Additionally, the blown head gasket may have caused further problems in other engine parts or caused irreversible damage to the engine.
If the blown head gasket has caused catastrophic damage, a complete engine may need to be installed or a new vehicle purchased. If the engine is redeemable, the head gasket should be replaced. When replacing, consumers should search by the make, model, and year of the car and obtain the newest generation of head gasket possible along with updated instructions and newer generation tools.
Vehicle owners should follow the instructions carefully so as not to damage the gasket during installation or cause damage to the engine in the future.
Alternatively, people should engage a professional to do the job. To replace the head gasket, a few major steps are required. The first step is to remove the cylinder head from the engine block to expose the head gasket. Both the head and the block should be inspected for damage, flatness, or any problems that may have caused the gasket to fail or may cause future head gasket failure.
Both the head and block should be cleaned with solvent and lightly brushed to remove debris. Sanding or polishing the surface can also help remove any residue. Do not overwork the surface; use a bead blaster, or hammer on the head, block, or gasket, as overworking or damages are irreversible. Some people prefer to let the dressing cure for twenty minutes to an hour before placing on the block.
That is because the increase in working temperatures, torque, power, and compression adds to the stress on the vehicle. As such, you are more likely to need to find the cost to fix the head gasket if you have a performance auto. So with that in mind, it should come as no surprise that the cost to replace the headgasket will depend on the make and model of your vehicle, its age, and the extent of the issues with the head gasket.
There will likely be one cost to fix the head gasket and another cost to replace the head gasket. The blown head gasket cost is so high because of the labor typically involved, in addition to the head gasket part cost. Simply put, there are a lot of head gasket labor hours required in the repair. Essentially, the mechanic needs to start by disassembling the entire engine, which takes a great deal of time. Then he needs to make the repairs, and only then can he put it back together.
Putting an engine back together is not quick work either, as it requires a high level of precision. The smallest error in the cylinder timing or other settings can result in misfires or future challenges. To avoid surprises, most mechanics will give you a head gasket repair estimate before they begin work. At the very least, they can provide you with the average cost of head gasket repair for your particular vehicle. Just keep in mind that the cost of head gasket repair may be higher than the estimate you get.
Your mechanic may find additional problems as they replace a head gasket. Good mechanics, however, will keep you updated and let you know about other issues that they discover that can affect the engine head gasket repair cost. As with most other problems, how much does it cost to replace a headgasket when you catch the problem early on will be less in most cases. If you notice the problem early, the issue is likely not going to be as severe, as it has not yet had time to worsen.
As such, you can typically expect to pay less for a head gasket leak repair than you would for a full Subaru head gasket replacement. Early repairs are more likely to let you learn how to fix a blown head gasket without replacing it. It also avoids high intake manifold gasket replacement cost or intake manifold replacement cost. Keep in mind that the cost to replace an engine is more than the cost to repair a leaky head gasket.
The engine replacement labor cost is also higher than a leaking head gasket repair cost. The best answer to how to tell if the head gasket is blown or what are the signs of a blown head gasket is to consult your mechanic.
