2.3 blow-by?

I was poking around under the hood with the car idling today trying to pinpoint the source of the tapping the car has had since new, and decided to crack open the oil fill cap. There is a lot more air coming out of there than I'm used to. I would say about half the volume/pressure of what you feel at the tailpipes at idle. Anyone ever try this?

Idk if any one still out there, but quick question. Should I have any pressure on the backside vent line? I notice my 2.5 had pressure at the cap but non at the vent.
