Turbo'd set up with no pcv... why?
 
We recently worked on a twin turbo'd corvette and the previous owner had removed the pcv, plugged the valve covers and intake and used two open elements. Is there a reason they done this? I've seen pcv systems on turbo'd cars before. We plan to go back with a catch can etc. if they're wasn't a reason. Any input is appreciated.

The first time getting my car tuned after going forced induction I pushed the timing cover seal out of the engine on the dyno. It blew 5 quarts of oil everywhere and almost gave me a heart attack. The stock PCV system was not enough to keep up the crank case pressure. I removed my pcv system and I now vent all 3 rocker cover ports to a vented catch can. This has been working for me for the last 5 years or so.

On a pressurized motor, there is no reliable vacuum
source (intake can swing to either side of ambient
pressure). So nothing for PCV to draw to. Unless
you ran a full time vacuum pump or something.

the intake is a reliable vacuum source. the intake is in vacuum for 99.99% of its life.

i make cans that work with full factory pcv intentions but they also can handle that .01% with ease :)
