PCV valve is indeed needed. It actually closes at idle, and, if the right one, again under boost. It only flows in between.
Either use a 323GTX turbo style PCV, or stock valve with added check valve. I don't think it matters which side of the catch can, but if between the can and the valve cover, the can will see boost.

Run a quality can on each side. On the pass side run from the pcv or chk valve to the can then to the intake manifold orig. spot. On the dr side run the line from the valve cover to another closed can then to the intake tract somewhere behind the kn filter Not the bottom of the filter. The highest vac is idling which is drawing a vac through the pcv [which does not completely close in that direction] or chk valve. The air source is from the other side being vented into the intake tract which has very low air flow going on. As revs increase and vac decreases the pcv or chk valve starts to close and when closed at high rpm's the air hauling *** past the hole in the intake tract well create a vac., but that line needs to be plumbed into the hose and not the bottom of the filter to create the vacuum. The same thing happens but even better when FI as when in boost the valve closes and the air in the intake tract is really hauling creating even more vac then when NA. I just bought 2 Radium engineering catch cans and this is the setup I am going to do.

Better yet, pull from the driver side vent instead, bUT that the one yout need to enlarge the vent hole on, aND add finter media.. Don't use the other one, where the oil pools.
I did both of them, but I'm 97% sure that my bent breather would have solved everything. Of course that's because it was my idea.
