Kent Head Gasket Repair

Overheating is a symptom of a faulty head gasket. A faulty head gasket either means an expensive repair bill or a trip to the junkyard for most vehicles. This is a major repair that can be rather expensive. Basically there are two ways to repair a faulty head gasket. One is effectively a temporary repair that uses a sealer kind of substance that will act as temporary head gasket. This substance contains particles that penetrate the faulty head gasket area and lock together and form a hard bond creating permanent ceramic seal. If your vehicle can idle for at least 20 minutes without having to add coolant or overheating, it is a good candidate for this product. Although this kind of product works effectively on aluminum or cast iron heads and blocks, it is still
only a temporary repair.

The other method to repair a faulty head gasket is to bring your car to Premier Automotive Services and let our Kent head gasket repair technicians disassemble the upper part of the engine, replace the faulty gasket and then reassemble the engine. While this method of repairing a faulty gasket is somewhat more expensive than using some kind of sealer, it is also a considerably more permanent repair. However, most mechanics won’t tell you that if you own a vehicle that has aluminum blocks and heads, about 40% will suffer another gasket leak between three and six months later. The only other option is to use some kind of sealer.

It is important to understand what the gasket separates in order to understand why a gasket, which is relatively inexpensive, is so expensive to replace. Pistons are inside the engine block and travel up and down in bores of the cylinders. These pistons are connected to the connecting rods, which are connected to a turning crankshaft, which provides power to the vehicle. The cylinder head is bolted to the upper part top of the engine block. Valves that open and close to allow fuel and air into the combustion chamber and expel the spent exhaust gases are contained within the cylinder head. The gasket is compressed between the cylinder head and the engine block. The internal combustion process is sealed by the gasket, which also serves to prevent the oil and coolant from mixing together as the two fluids travel between the cylinder head and the engine block. Our Kent head gasket repair technicians undergo extensive training. These replacement gaskets are relatively inexpensive. What is expensive is the dis-assembly and reassembly of the engine. Replacing the head gasket involves removing the cylinder head from the engine.

There are many different reasons that gaskets can fail. The usual cause is overheating of the engine. During this overheating, the metal of the engine head and block expands beyond its normal limits. This expansion can crush the gasket causing it to fail. Engine detonation or pre-ignition is another major cause of failure of the gasket. This results in the combustion within the engine cylinder to be out of time. It is only when the piston is at the top of the power stroke and both valves are closed that internal combustion is supposed to occur. Combustion that is out of time places additional strain on the gasket, pistons, and valves. However, when an engine overheats, it also increase the possibility of detonation or pre-ignition. Damage is being caused whenever you hear the noise of an engine knocking or pinging.

The average mechanic shouldn’t attempt to replace a faulty gasket, our Kent head gasket repair technicians are well trained to do this. A head gasket that has been blown for a while can mean that other internal engine components might also need replacing.

We understand that making sure that your engine is running properly, in tune, and the cooling system in good working condition are the best way to prevent the failure of your gasket.
