Supertech GM Ecotec Integral 6mm Viton Intake & Exhaust Valve Stem Seal - Single (Drop Ship Only)

If you're rebuilding the top end of your GM Ecotec engine, replacing the valve stem seals is a crucial step. These seals keep oil from getting into the combustion chamber through the valve guides, preventing blue smoke on startup and oil consumption. This particular seal from Supertech is made from Viton, a material known for its excellent resistance to heat and oil, which means it'll hold up well in the demanding environment of your engine.

This is an integral-style seal, meaning the seal and the spring retainer are combined into one piece. It's designed for 6mm valve stems, which is common on many GM Ecotec applications. Using good quality seals like these helps ensure your engine runs cleanly and efficiently after the rebuild.
