RJC Racing PCV
This is an industrial Viton sealed check valve that will not leak under boost and should last forever. Unlike stock steel PCV valves that leak under boost this Billet brass valve features Viton positive action seals that do not leak under boosted conditions. When the stock PCV leaks it causes pressure to build in the crank case causing oil leaks everywhere. This simply replaces your stock PCV for a trouble, maintenance free PCV. On the shelf now.
