PCV setup 
Guys , looking for some input... this is currently how I run my turbo l33. I daily my car and I'm constantly pulling full vac on my cc, I just changed my oil and I'm noticing a decent amount of magnetic material on the plug. Is it possible that I am pulling the oil from the rings with this full vac setup? Should I remove the pass side hose and let air enter and circulate the cc like the factory setup?
Thank you.
I have mine set up with a vent to atmosphere when under boost.
btw i have never heard of pulling oil from the rings....what is that?
my guess would be the two things are unrelated.

You put a filter on 1 valve cover, and pull from the other. You dont need a valve on the filter side. You are pulling a constant supply of fresh air through the crankcase while cruising from the manifold vacuum and the other one to the turbo inlet is sucked close while cruising because manifold vacuum is higher than compressor inlet vacuum (venturi affect). Then under boost the valve closes and the compressor inlet flow increases and pulls the fresh air through the crankcase.
Your on the right track. This type of setup is exactly the way I prefer to run it, with the exception of placing either a small catch can between the valve cover and filter in the event splashing oil gets to it or high crankcase pressure pushes out for other mechanical issues or a stuck valve etc. Or you relocate the filter to a higher location in the bay or use what companies call a "clean side separator" which is basically a little baffle/filter on the valve cover that then connects to the small air filter.
