At a minimum you should vent to atmosphere and not back into your intake of the turbo from the valve cover.

 

I have been thinking about making my own intake, is see where you can purchase the little fiter that goes onto the valve cover (anyone know a good place to get one). Also the large tube coming from the bottom of the greddy intake, where would I hook that to?

 

For those with the Greddy Oil Catch Can. Does it actually work? Just wondering because wouldnt it be ineffcient seeing it doesnt come baffled?

 

it worked on my car, but i'm sure with an internal baffle it would work even better.

 

I would like to know this also. I will try venting to the atmosphere. I may go catch can down the road.

 

I just blocked off the pipe that the large hose attached to on the Greddy Intake and then am running the filter on the valve cover.

 

Maybe Chris can chime in on why the larger hose is need, TRBOKEV where did you get the valve cover filter?

 

Local speed shop. I'm sure you can find them on EBAY also.
The tube is there for CARB purposes.

 

The smaller hose goes to the valve cover as a part of the PCV system and the larger hose goes to the air pump...i'm not an expert at the air pump and the technicalities of it, but i'm assuming that's where it draws the air from. Both affect emissions, so keep that in mind if you still need to pass carb. Not sure what ppl usually do with that hose when they keep the air pump (some get rid of the air pump). You cold probably just use a straight union and put a filter on the end.....but don't quote me on that!

 

I kept the air pump (Just to clarify). It helps on warm up of the car.
