PLM Precision Works Oil Bypass Check Valve Plug Fits LS1 LS2 LS3

Precision 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.

Why would you ever let unfiltered oil into your expensive LS engine? Install one of our Bypass Deletes the next time you change your oil filter.

A 1/4-20 threaded hole in the end of our Bypass delete is for easy removal. Just screw a 1/4-20 bolt in and pull the delete out if ever necessary.

Better engine protection from less particles bypassing, replaceable High Temperature Viton O ring and for ease of service a threaded 1/4-20 hole.
