just looking for additional information i currently have my set up with one vent blocked the y vent one side to catch tank and the other side to the PCV valve. The valve covers are T together and routed to a Perrin intake hose. I will try to post a diagram as soon as i figure how. I am not 100% sure that this is the best way looking to get feed back and possible alternatives and why you went this way just so i can have some good data to compare.

That's similar to what I did. I blocked off the central vent (the unbaffled one) and ran 3 large breathers tubes from the head breathers and baffled crankcase breather VTA. Blocked off the PCV valve in the intake manifold and I'm not running anything to the intake tract.

Basically, there's no vacuum on my crankcase. But there's also no chance of oil and exhaust gasses re-entering the intercooler / combustion chamber.

My motor is still in pieces.. but from what I understand and read, vacuum in the crank case is a really really good thing. This'll be installed and I'll throw a vacuum gauge on it before I hook all of my PCV hoses to it.. PCV is important when seating rings, too. I also don't want any un-metered gases entering my combustion chamber, or that disgusting oil that likes to coat my IC hoses and collect in my core - even though I run a catch can.

Turbo Chryslers came with this style of PCV, and I sent an email to someone smarter than me that doesn't see any reason why it won't perform well.
