lol you have dual overhead cams. of course you're going to feel air moving if you open the filler cap. it's not a problem, it's all those moving parts! i'm surprised you didn't spray oil all over.

I think you will always feel air coming out of the oil fill hole over the valves. Isn't there ventilation to the valve cover to equalize pressure? At least I was pretty sure that the pressure needs to be equalized within the valve cover. Someone else more knowledgable about that should be able to tell you. As far as I remember (haven't taken my oil cap off witht he car running on my cobalt) but my old cavalier and probe both had air coming out of the oil fill hole if you took off the cap while the car was running.
