vaccum air/oil seperators

[tb3]

anybody run one?  say like, something similiar to this one here  http://www.summitracing.com/parts/CTR-23-050

i'm gonna assume not very of us for our cars.  but i know some have.

if so... what was basis for you deciding to install one. and hows the results been?

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.

As said many times, fix the problem and you won't need one  :smt017

[tb3]

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;

I think check valves are a gimmick...but, if it makes you sleep better.....

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?

[Steve Wood]

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"

[tb3]

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
