PCV/Oil Catch can setup on s13.4 valve cover
 
Hey guys I've been trying to research this for over an hour now and there doesn't seem to be a direct solution. Everyone seems to do it a little different. Just got a s13.4 valve cover back from touge factory and they welded 10AN fitting on all the vent points including PCV.
I didn't really understand the pcv before because otherwise I might have kept it. I need to know how to run my catch can now without a pcv. I basically have 4 openings that need to be plugged or connected. The 3 on valve cover and the one on back of engine block.

I can account for 3 of them:

Line from fitting on exhaust side of valve cover to hole in back of the block, line from exhaust side top of valve cover to your catch can, line from catch can to turbine inlet. As for the PCV, I have no clue why they’d do that, but they do make -10AN one-way check valves you can use to maintain the PCV.

Yeah I just bought a radium pcv valve and some fittings to make it work. I saw some people run a 3rd open line from it to catch can but I'd rather be safe I think and keep a pcv valve there.

A lot of times the PCV is deleted altogether. Maybe they assume or it is standard practice and was missed in the details.

On mine I have the block one connected to the one above it. The right side one going into the catch can. And the pcv back into the intake manifold

That's how it typically is when you have a pcv valve still. Do you have one? You can't really just plug the pcv side into the manifold without the actual valve otherwise your pressuruzing your crank case.

Install an inline check valve or a Krank vent.

Yea I am running a pcv. Previous owner of the cover welded on a female fitting of some sort and had a 10an fitting on there. Luckily it matched the pcv threads

Honestly I don't run catch cans with the 13.4 valve cover.
