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!
The PCV valve does restrict the vacuum. I hope you got all this sorted out.
