your doing both. if your letting unmetered air in.... theres got to be a vacuum to suck it! if you take the oil cap off the valve cover, the rpm's will increase. put your hand over the hole and you'll feel the vacuum and the rpm's will go back down. lets say you disconnect the line from the pcv to the intake, wouldn't that be a vacuum leak? its still sucking ambient pressure, whether it goes thru the engine first or not. its less than ambient pressure where it taps off at the throttle body, which means less differential pressure, which equals less flow.
