The fittings off the vc will suffice but opening up the pcv will also help vent it more I suppose.I spoke to you at 8th fest about the cc .I was the older guy with the teal hatch and walked over and complimented your catch can. I forget who made it but it was a nice lookin cc I don't think you had it hooked up yet but it was in the bay .I run two -10 an fittings off my vc and am boosted to about 24 lbs my pcv is not open just unhooked it to keep oil vapor out of the engine intake tract .
