COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides.

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 .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.
