Oil System improvement LS Barbell 4.0 - Pickup Tube Hold Down - Bypass Delete

LS BARBELL 4.0
The oil galley oil diverter Barbell in your Gen III & IV LS based engine is something that is overlooked. And yet it serves a very important mission of directing oil to the oil filter. If oil leaks past the Barbell, it will go unfiltered directly to the Cam Bearing, Lifters, Crank and Rod Bearings. The factory Barbell is approximately .020” smaller than the oil gallery, so particles as big as 250 microns can leak past the factory Barbell. Your oil filter will filter out approximately 25 Microns depending on the brand of filter. As the original inventor of the Aluminum Precision fit Barbell, we are always striving to make improvements. Our latest 4.0 update has, as with our previous versions, we use 7075 Aluminum unlike our competitors that are using cheaper 6061. Our 4.0 Barbell has a wider sealing area on the front of it, eliminating the need for an unreliable Oring. During our prototyping we tried an Oring on the front and when installing it, the Oring was getting sliced and chipped on the sharp internal oil ports and left Oring remnants that could have gotten in the lifters and bearings.

That’s probably why GM didn’t put an Oring on the factory Barbell.
Our Precision Billet Barbell fits with approximately .001” clearance which might only let 20-25 Microns pass by, that is the same or less than the oil filter. Another important part is the shaft of the Barbell. The oil must flow around it to get through to the oil port. Our latest design 4.0 Barbell has a 30% smaller shaft plus a more tapered design for much less flow restriction. We have also added a 1/4-20 threaded hole in the end of our Barbell for easy removal. Just screw a 1/4-20 bolt in and pull the barbell out. No more digging and prying to get the factory one out.

Better engine protection from much less and smaller particles bypassing, smaller less restrictive shaft for better oil flow, replaceable High Temperature Viton O ring and for ease of service a threaded 1/4-20 hole.  Why would you ever put the plastic factory Barbell back in your expensive Gen III & IV LS engine and let unfiltered oil in?  Our Precision LS Billet Barbell 4.0 Stops Unfiltered Oil & Increases Flow!

Tech Note: Always make sure your oil is at operating temperature before running your engine hard! Also use a quality oil filter!

Gen III & IV LS Oil Pickup Tube Hold Down (PTHD)

Billet Bypass Delete 
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 engine’s bearings and lifters. Our Billet Bypass delete plug 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.   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. Why would you ever let unfiltered oil into your expensive LS engine? 

NOTE: Make sure your Bypass valve is located in the filter adapter housing like in the picture BEFORE ORDERING! Some are located in the oil pan!
