Ugggh, I closed this window before I finished typing.

The block and head vents are separate from the factory for a reason. WHy? It can be debated but I accept that Subaru and other manufacterts know what they are doing (although they may do things cheaply).

Now, Litespeed uses 2 cans and 2 check valves and removes the PCV. ONe can is for the block and one for the heads. I don't think you need the head can except in track applications as I have never seen or found oil in the head breather tubes. The check valves connect to the intake manifold and turbo inlet to always pull strong vacuum through the block can. During cruise the manifold has strong vacuum and during boost the turbo inlet does. Now I have no idea how good the actual cans are that Litespeed uses; most cans are empty, no baffling or swirl pots. Crawford, IXIZ, Grimmspeed all use soem sort of baffle to remove the oil from the air. I just dont like how any of them are plumbed.

I plan to DIY a setup using a cheap Ebay can like this- http://www.wrxfanatics.com/index.php?showtopic=59698 but plumb it like the Litespeed setup using check valves from McMaster Carr- http://www.mcmaster.com/#7775k64/=68xwmh
