GM Gen III IV Oil Bypass Check Valve Delete LS1 LS2 LS3 LSX *CBW-072
Keep unfiltered oil out of your engine by plugging off the oil bypass check valve. The factory bypass check valve can let unfiltered oil into your engines bearings and lifters. The HAWKS Motorsports 7075 billet aluminum 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.
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.
