Yep, very possible. With the stock inlet functional, a leak between the crankcase and intake would act as a slightly stuck PCV valve, the air is already metered and accounted for, so the IAC takes care of keeping the engine at the right RPM. With the inlet blocked and the breather on, it would be a vacuum leak.

With both the inlet and outlet blocked, you should have positive pressure on the front valve cover, not negative. For the IC to be at fault here, it would have to be a serious design defect, such as the core extending all the way into one of the PCV passages.

Ive had this thing on and off more than enough times. Im done screwing with it. I know i had enough silicone on it ensuring there wasnt a vacuum leak. Tested it everytime with carb cleaner to second that there wasnt a leak. Like i said i didnt even use a new S/C gasket the last time when just putting the S/C back on and no intercooler and everything is running fine. Not going to mess that up. Havent been able to drive the car for over a month and a half so now that i am able to drive it now, dont wanna be taking everything off again. I know im not gonna get a refund for this so just gonna sell it. Next time i know i wont be buying something that hasnt been fully tested. Live and learn.
