M60 Non-return Valve
Hey all, I just completed changing the intake gaskets on my M60 and neglected one detail when putting everything back together: the orientation of the Non-return Valve that is in the vacuum line that comes off the driverside of the PCV valve. The car seems to function with it in either orientation however I think there should be a proper way. Attached pic shows the part I'm talking about, it's the small black & white piece right above the big black wiring box.
