Precision Works Oil Bypass Check Valve Plug Fits LS1 LS2 LS3 Engine Mounts designed for high-performance builds demandingPrecision Works Oil Bypass Check Valve Plug Our Billet Bypass Delete replaces the factory check valve preventing unfiltered oil from getting into the engine. The factory bypass check valve is a safety in case the oil filter never gets changed and the filter gets restricted. Most oil filters already have a bypass built into them for this reason. The factory check valve can open with oil pressure surges, letting unfiltered oil by and into the bearings.
