this is a very interesting post- i never knew there were 2 kinds of catch cans. E- check this out. http://www.honda-tech.com/zerothread?id=383478
so... wouldnt you be loosing potential power from this contraption? Does a car run "better" without this hooked up. I'm sure you need it for emissions. The way I see it, all it is doing is contaminating perfectly clean air.
No- normally for emissions, you just have a straight hose connecting the crank vent and the intake manifold... this way you get the oil out before it dumps into your intake.
