LS6 valley cover - what is the difference?
LS6 valley cover - what is the difference? I keep reading that the LS6 valley cover is a partial solution to oil vapor issues but I have never seen a pic of the LS6 cover and don't know the difference. Could someone please explain the difference and maybe post some pics?
Thanks
Thanks
That mod is something nice you can do. It'll keep you from having low oil pressure and comsuming so much oil. It basically has a return valve at the front of the valley cover that pumps and circulates the oil from just being thrown in from the rear of the intake and just sitting at the front of the intake and burning off.

I was just doing some research on this the other day......The LS6 valley cover allows you to move the PCV system from the passenger valve cover to the valley. The LS1 PCV system can be a source of oil consumption, so this could be a good mod if you have that problem. It also lets you get rid of a long, ugly PCV hose that runs along the intake. Here's a link for the conversion:

Well, you guys have lead me to spend more money again 
. I am ordering the cover today since I already have the intake off the car for paint. I like to idea of cleaning the intake area up by removing another hose. I just got rid of those ugly AIR tubes as well. The aluminum rails will look better since there will be a whole lot less clutter, and the reducing the oil consumption will be nice too. 
Thanks for the post.

I realize this is an old thread, but the info is new to me. I’m getting ready to do an intake swap, so I guess I’ll have to add this to my list of things to do while it’s off. Great info guys.

My 01 ls1 block had to be notched, it's not that hard to do honestly. just be sure to make sure everything is covered up good. I believe the whole process only took an hour or so but block was apart, heads and intake were already off.
