Audi 90 Valve Seat

The Audi 90 was the final evolution of the Audi 80. During the development of Audi 90, many popular parts have been built such as the valve seat. Once the proper width for the mating surface is formed, the valve seat can be properly seated to the mating surface of the valve and supply good sealing as well as heat transfer when the valve is closed. The Audi 90 valve seat is a vital part of an engine in that if it is not properly placed, oriented, or formed during the building process, valve leak leakage may occur.
