Will this PCV setup work on turbo car? Same setup I've ran on ATI cars.
The car had the back drivers side valve cover grommet running to the air intake in front of the turbo. The rear passenger, TB nipple, and intake manifold nipple were plugged off, and the front nipple on pass side was open to atmosphere/breather.
With this setup the car smoked really hard at idle, smelled like oil smoke.. didn't have the blue tinge that I would expect with the amount burned though.
I put crossover connecting two rear grommets and a PCV valve running to the intake manifold (stock style setup) and the fresh air inlet normally running to the TB - ran that to the air filter pre-turbo/boost etc.
95% of the smoke is gone. The plugs are still pretty greyed up so they need to be changed still, but definitely seemed like it was burning oil previously. Gonna have to look at the plugs after some fresh ones go in and regap them they were little wide at .047"
Only thing Im concerned with is it pulling oil into the air inlet. Would putting a breather on this fresh air line work or what about putting a catch can in route to the airfilter

id just vent all of them by filter, you definatly dont want anyone hitting the turbo like that, you can run a catch can from the valve cover to a breather, which would help out with oil drippings
I am running the Mighty Mouse set up. Breathers on both VC and an LS6 valley cover that is connected to the inlet of my turbo. The more boost you make the more evacuation of pressure from the case. I havent sucked any oil out yet and dynoed up to about 6700 rpms. So far I think it is working pretty good. The Metco VC breathers are nice.

Thats what I am thinking is run the two rear VC ports (normally intake manifold vacuum) to a catch can/breather. Then run a LS6 valley cover, to a air/oil separator.. to the intake side of the turbo, so under boosts its gonna pull the vapor out of the crankcase, drop out in the separator, but hopefully keep neg. pressure in there to seal the rings as best it could. Correct angle would likely be important to keep the pressure right when setting it up in the inlet however
Im just worried with the original setup if it hurt anything, a LOT of oil had to go thru that turbo sucked out of the vacuum ports on the cover, to make the plugs look like that.
#1 thing with the breathers is running enough surface area to them if its remote mounted Id think
