90/90 & PVC question
After putting on the fast intake & LS2 TB where should I hook up the PVC? There is one hose connection coming off the intake,Should I hook up the PVC there? I have the filter that replaces the oil cap if I have to go that route just in case.On the old TB (78mm) There was a hose going from the valve cover to the TB,There is no connection to the LS2 TB.I saw a picture where the hose went from the valve cover to the coupling for the TB to the air filter,But I wasn't sure.Thanks......................Paul

I would replace the coupler with one that has a hose or put one in the air bridge. If you put in a filter on the valve cover, and then connect the PCV to the intake, you have air entering the intake that the MAF is not aware of and I'm not sure how that will affect the mixture but its almost like a vacuum leak.

What about getting yourself a three way tee and running the hose from the passenger valve cover to it and then from there hook it up to the PCV and the intake port? I'm not familiar with the FAST intake but am assuming there's a port on it so you can hook up to the PCV valve. I don't know if I'd replace the oil cap with a breather.
