COMP Cams offers a complete line of valve seals, from the stock GM O-rings to the positive-stop PTFE seals. They are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The O-ring seals use the standard retainer and oil splash shield. The umbrella seals are normally used when a larger-than-stock diameter spring is used. In the case of a double spring, the positive stop PTFE seals are used. For triple-spring applications, use the smaller-diameter Viton® seals.

These Chevrolet Performance valve stem seals control the lubrication of the valve stem as it slides into the valve guide. Too little oil contributes to stem and guide wear, and too much oil increases oil consumption and can cause a buildup of carbon. This leads to valve seat damage and early valve failure, as well as reduced engine performance and emission failures. These Chevrolet Performance valve stem seals ensure dependable performance and superior service life.
