Most engines are constructed of two major components, the engine cylinder block, and engine cylinder head. These two halves must seal to one another, and act as one piece, or the engine will fail. The head gasket is a sealing layer of durable material that is sandwiched between the cylinder head and cylinder block. When tightened down, the cylinder head crushes the head gasket into the cylinder block, causing any imperfections to be sealed by force.
