To Catch can or not to catch can…???
The PCV valve is garbage and leaks on most of these cars. When you get into boost it will allow air to pass through which pressurizes the crankcase. This usually causes the dipstick to pop out since the breather on the VC can't relieve enough pressure. It also makes for difficulty in the return of oil to the pan.
Best thing you can do is run a line from the PCV port to a catch can then put a quality check valve in-between the catch can and the manifold. Then, enjoy not having oil inside your manifold!

Going to put a dual catch can system in soon, getting a lot of crap in my UICP.
I also learned well what happens when that breather hose gets kinked
