I modded my PCV system to where it has a "T" down at the black box on the back of the block that goes into it where the stock PCV normally would. I have one vacuum line running to the IM just as it would on a factory PCV system but I put a little check valve inline with it RIGHT before it connects to the IM, then I have another vacuum line running from the black box to the pre-turbo intake pipe. Basically, when Im driving around not in boost, the crank case will be vented from the vacuum of the IM, but when Im in boost, the check valve on the vacuum line will close just as the factory PCV valve would. While it's closed, the crank case will then be vented from the vacuum of my pre turbo intake pipe via the other vacuum line running from the T at the black box. My question is, if I were to run a catch can...would I put it in between the pre turbo intake and the black box? I want to keep oil vapors out of my charge piping and intake system all together. That seems like the only place to put it.

I hope all this made since and I hope I can get some help. Thanks in advance!

ok so I pretty much did the intake slashcut evacuation method but I added the part where when driving N/A it still uses the IM as a vacuum source as well. And I guess that answers my question. I should put a catch can in there to stop oil and contaminents from getting in my intake system. Will a non open filter catch can work just fine too?
