I recently cleaned my Moroso oil catch can (with release valve). When I first installed it, the pressure in the catch can was positive (when I opened the valve, air would rush out). Now there is a vacuum when I open it. I switched the hose orientation but still get a vacuum. Is this normal? Don’t know how I screwed this one up. Any help would be appreciated.
