Valve seat is the surface against which intake and exhaust valves rest when they are closed. It is a very critical component in the operation of a combustion engine for if it is not properly positioned, oriented, or formed during manufacturing valve leaking will occur, resulting in a loss of compression.
Valve seats are usually formed by first press-fitting a cylindrical piece of a hardened metal alloy, such as Stellite, into a cast depression in a cylinder head above each valve stem position, and then machining several conical-section valve seat surfaces to form the valve seat into a shape that will match the mating surface of the valve.
