Cylinder head gaskets are sealing elements for the combustion chambers of the engine. They are installed between the cylinder block and cylinder head. The gaskets prevent leakage of gases from the combustion chamber, and of coolant and oil from their respective channels. These components are disposable and should be replaced each time the cylinder head is dismantled.
