COMP Cams® offers a complete line of valve stem seals 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 seal is normally used when a larger-than-stock diameter spring is used and in the case of a double spring the positive-stop Teflon seal is used. Smaller diameter Viton seals are also available for triple spring applications. Both the O-Ring and the umbrella seals require no machining but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special cutter.
