I'll be interested to know what you find out after the switch. They make inline PCV valves that you can put in the hose. They are cheap, would be worth a try if the noise follows the move. If the popping is caused by a lean condition, that could be happening because of an unrestricted vacuum "leak" when at idle as that is a high vacuum condition. At higher speeds, more air would be flowing through the throttle body and bringing fuel with it so the lean condition would be reduced. Not sure why it would just show up on one side though if the port opens into the plenum.

Of course, that's just my opinion, I could be wrong!
