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?

Yeah, it's normal, and I found out the hard way, I work at a Ford dealership and the customer wanted some oil additive we sell, so I change the oil and fill it, then put the cap on to check the oil. Then I remembered I forgot to put the additive in, so while it was running I tried pouring it in, and ended up wearing it lol.
