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.

NOTE: Make sure your Bypass valve is located in the filter adapter housing like in the picture BEFORE ORDERING! Some are located inside the oil pan, this product will not work if your delete is inside the oil pan.

all GM Gen III & IV LS  Engines and is a must have part! MADE IN THE USA!

    I originally intended to use this on my 2000 WS6, but realized i had installed a newer style oil pan that has the check valve delete built into the oil pan already. So, i decided to install it on my '06 tahoe instead, and it worked out great!

    Didn't come with instructions, so here are some tips. You will need a 13mm or 1/2" hex socket (allen wrench) to remove oil filter adapter screw. I used a 3/8"- 24 bolt that was 4" inches long, and force threaded the bolt into the check valve. Then i Wiggled the bolt around until the check valve popped out.
