Re: Help with LS3 connections and PCV

So here's what I've done on my L92's dressed as an LS3. Using a LS3 Corvette intake, valley cover with PCV and throttle body. Look's just like your LS3.
Nipple on the left valve cover is capped off.
In the pic on of the first post of the throttle body and intake. I cut of the nipple off and drill and tap the hole plugging it. Not needed on my swaps.
Pic of the back of the intake the capped nipple is for power brake brake booster if needed.
Then I connect the intake nipple on the right side of the intake (right behind the throttle body) to the nipple on the valley cover that contains the PCV assembly on the under side of the valley cover.
On the right side valve cover the fresh air tube I connect it to the air intake after the mass air flow sensor. Piece of cake. LOL!
