Frequent engine overheating; white smoke that smells like fuel coming out of the vehicle's tailpipe; engine oil contaminated with water; coolant contaminated with engine oil; oil or coolant leaks from between the engine head and block — all of these surely spells problem for your Chevy. Identifying the damage, however, is kind of tricky because these symptoms may indicate a variety of problems. These can be symptoms of a cracked head or cylinder block, a damaged turbocharger, or a blown head gasket. Of course, many of us would wish for the least damage, and that would usually mean wishing for a blown head gasket.

A head gasket, or cylinder head gasket, is a gasket used to enhance the sealing between the cylinder head and the engine block. Different kinds of materials are used for the manufacture of head gaskets although it is common to find graphite head gaskets or multi-layer steel (MLS) head gasket on late-model automobile engines. These two materials are specifically preferred because they can withstand the effects of engine oil, coolant and gasoline. They are also known for their stability and rigidity even in extremes of temperature and pressure.

Now, are we better off if the symptoms previously mentioned were caused by a blown head gasket rather than a defective turbocharger or a cracked head or cylinder? If you consider the price and the availability of the components to be replaced or repaired, then a damaged head gasket is definitely better than the other damages. You can find a lot of high quality yet affordable replacement Chevrolet head gaskets today through reliable online auto parts sources like Parts Train. The complexity of replacing a damaged head gasket, however, is not a task to wish for, especially if your Chevy is equipped with complex V-type engines. And should you decide to let a professional mechanic or an auto shop replace the head gasket for you, better brace yourself for whatever amount you have to spend.

So what makes replacing the stock Chevrolet head gasket with a new one complicated? Actually installing the head gasket may be simple, but the things that you must do before you can install the gasket is the one that makes it complicated. Depending on the type of engine installed on your Chevy, you must disassemble several engine parts before you can get into the cylinder head gasket. Removing the old gasket also requires much care so as not to damage or warp the surface on which you would install the new gasket.
