Pcv

So I bought a crate motor ls3. There is a apparently 3 pieces to the pcv system 1 in the valve cover on the front passenger side valve cover which hooks to the fresh air intake. The 2nd is in the front of the intake. This one came already hooked up to the throttle body. The third comes off the rear of the left valve cover. So where do I plumb that or do I just leave it pluged? Thanks for any input.

Re: Pcv

Best I can determine from the net is there is no pcv valve on a LS3....just a orfice... and I think this is it...loops from valley cover up to Intake...

Re: Pcv

Yep you're right that answered my question looks like the rear one stays pluged. Thank you.
