The valve shakes and is new, I can blow one way through it freely and the other way is much reduced.

Should it be installed to reduce vacuum at the valve cover side or installed to allow free vacuum from the intake to the valve cover?

Right now I am having difficulty removing the oil filler cap with the car running, it is far too much vacuum, which makes me think the PCV valve should be restricting vacuum to the valve cover, not allowing it.

Thank you for your help!
