Can't find what I'm looking for. Im trying to find the best way to plumb an oil catch tank or 2 if needed ive read lots of threads on different forums either they are on an na motor which mine is boosted or they only do pass or driver side or they post what they did and then change half way through the 5 or 10 pages so its confusing do I need a check valve ? Will the pcv valve stop boost from entering the valve cover ,but I'd still like vacuum for propper ventilation what do you do with driver side please let me know what is the best way?

There are a lot of different ideas. My set up has both valve covers going to a custom catch can made by boosted performance. It then exits out to one of my downpipes. Seems to be doing well.

 

2JZ never use any vacuum.

Just T both valve covers into a vented catch can.

simple and effective and is the way platforms with years more experience do it.

Yes , all PCVs are basically designed to block surges due to backfires, It would be bad to ignite the gases in the crankcase. That same check valve action blocks any positive manifold pressure from pushing back into the valve cover.
