I have a 08 LY6 6.0 (Essentially an LQ4 with L92 heads). I was under the impression that all GEN 4 motors made after 2006 had the LS6 style valley cover? Mine has a flat valley cover with no venting provisions. I am converting this motor over to carb with an edelbrock vic jr. I have a fitting on the front of the pass side valve cover and a fitting on the back of the drivers side valve cover, but nothing on the valley cover.

My options are A-switching to an LS6 valley cover, B-using my existing valve covers and running them to a catch can, and than back to the intake, or C- run aftermarket valve covers with a breather in one and a fitting in the other running a catch can than to the intake.

Is it possible to simply run an inline filter (like one on a air compressor, a small inline clear one) instead of a catch can? The capacity would not be as large, but it would work in theory? Any insite is appreciated. Thanks, Eric L

 

yes i know im a grave digger, but what did you end up doing ???

 

I am wondering myself.

 

I ended up running some Ebay valve covers with a open element breather on the pass side, and an 8AN fitting on the drivers side running to a breather tank. That way I can monitor how much oil/water im accumalating. And I can switch it around and try differant combonations of breathers side to side. I just left the stock LY6 valley cover in place.

I have an ls3 valley cover for sale that would solve your issues, let me know if your interested

 

Just for future "gravediggers", lol, Does the LS3 valley cover have the LS6 PCV set up AND the o rings for the DOD ports? Eric L

 

Yes, to both questions above

 

What is the LS6 PCV set-up?
How is it plumbed?
I had an LS1 now I have a LS3.
Trying to figure out how to plumb it.
Wanting to run breathers on the valve covers,
And not wanting to plumb back to the intake.
