Pcv hose routing

The LS6 valley cover is nice, since it gives you a nipple sticking out right underneath the throttle body area, and there is a U bend hose that is short and connects direct to the intake. They don't seem to pull a ton of oil from the valley, like they do from the valve cover on driver side.
If you stick a catch can between that driver side valve cover port and the rear intake port, I think you'll be good. At high rpm you may get some oil sucking in there into cylinder 7 and 8.
of course you will want to plug that MAP sensor hole and the other 2 nipples in the intake you won't be using, guessing you planned on that.

Thank you for the reply, and for confirming my research. The more I think about it I do like the idea of using a Ls6 valley cover both you and A1971Blazer suggest. I am hoping to be able to get this project running in the next few weeks, and as I said before I don’t want to pull it back apart right now, but I will next winter. A catch can may have to be the temporary solution.
