Review on 🔧 JGR LS Billet Oil Bypass Delete Valve - Ultimate Solution for Gen 3 and Gen 4 LS Engines, 4.8-7.0 LS1 LS2 LS3 L92 LQ4 LQ9 - Black Finish by Phillip Johnson

The product is not manufactured correctly and is not a 100% safe upgrade for an LS engine without significant modification. Both ends of this rod are the same diameter and if you remove the O-ring from the outside and insert the rod, you will immediately find that it is too loose to provide the internal port oil seal needed to keep the contamination out actually restrict oil from bypass. happen. So the only fix for this mismanufactured part is to add another o-ring groove to the opposite end to actually seal the spool in its hole. I have a lathe at home so it's not a problem but for the rest of you who don't have a lathe. Return this part, it will pass a lot more oil than a standard plastic rod.
