there have been some rigged to try to minimize the amount of oil sucked into the plenum via the pcv.   How much real benefit there may be, I don't know

My thought has always been that catch cans are a band aid solution for a bigger issue.

but what if the only "problem", was that it's a higher milage turbocharged engine, and you wanted to help keep it from developing problems.
a properly working pcv and adding a check valve is a major player, right? but I can't think of one good thing it will do for your engine by pulling blowby into your intake.  deposit buildups. gumming stuff up. fouling, detonation,... a $100 for a good quality Moroso air/oil separator, it can only be a win-win, right?  
I gotta feeling you guys are gonna say that if it makes me sleep better at night,... then go knock my socks off :flat;

moroso also makes them that don't need the vacuum pumps

this would be what i would go for if i where to add one.

steve, at wot and at say...28 psi,  even on a tight motor, your gonna be makin some pretty good crankcase pressure, right?    surely that check valve is doing you some good?
or do you just think their over-rated...as in, the valve cover breathers should be more than sufficient?

it is not the pressure that is important...it is the total volume that is pushed in.  Think how small a leak that a working pvc actually is compared to the volume that can escape thru the breathers...gi mmick in my opinion for those that don't think about the actual mechanics of the "problem"

I guess I was just kinda thinking along the lines of similar to exhaust leaks and vac leaks. where every little tiny bit can make a difference in your tune. but, I know, the pcv is a controlled leak
