Volkswagen Head Gasket
The head gasket is responsible for sealing all the combustion chambers as well as the coolant and oil channels between the cylinder head and block. A good working head gasket should seal well and ensure that it is leak-free from the moment it is installed between the cylinder head and the engine block and sustain or maintain that seal for as long as there is engine life. And that's the reason why the head gasket is considered one of the most important parts of the engine and one of the most critical gaskets in your engine.
Nowadays, engines are harder to seal because of the aluminum cylinder on cast iron blocks. These aluminum heads may weigh less but heat makes them expand so fast making it difficult for the head gasket maintains the seal. Also, the movements created when the engine is started eventually wear out the material of the head gasket. Low friction coatings like Teflon, molybdenum and others were used to prevent the gaskets from sticking to either surface allowing the head to expand and contract without tearing the gasket apart. The technique for cast iron engine is different because raised silicon or fluoropolymer elastomer sealing beads are applied to the face of the gasket to increase the clamping pressure. This improves the ability of the gasket to seal by holding it in place.
Head gaskets fail due to various reasons like overheating, incorrect installation and a defect in the design itself. Replacement should be done immediately so as not to affect more expensive engine and other auto parts or other systems.
