Their is a updated valve cover that helps with oil consumption. I replaced on my 08 tbss a while ago. Can't remember what side it was at the moment(sorry been a long day)

Thank you pcm of nc for getting my order shipped fast! I hope the pickup tube brace ships fast too. So just a change of a valve cover fixed this? This sounds better than the catch can. Is this a gm part or an aftermarket part and how can I get one? Part number anyone? Thanks!

GM inventory has been purged so the replacement driver side has a relocated PCV drain hole that prevents oil from entering the intake manifold. I don't run a catch can and my manifold is pretty clean. Not saying this will fix every ones issue but I don't currently have a issue with oil entering the manifold.

You got a part # for the updated valve cover? I'm going to give this a shot

Then it may be a rod bearing, rocker or lifter...you know for fact you have penis slap going on in there??
I'm sorry for the necro-bump but is this a nickname for piston slap or just a perfect typo that noone picked up on in 6 years?
