air comin out of oil fill....
I removed my oil fill cap today while the car was Idling... and theres Air comin out... not just a little bit of air.... enough that I can hear it whooshing out.... This can't be good What's the problem?????

that's normal... the whoosing isn't air pressurizing the crank case it's the sounds of the cams moving air and slinging oil. Every car I've owned with an oil filler on the valve cover has done this. It won't be turbo related since you shouldn't be boosting at idle. If you are I think you have far more severe problems to investigate.

Yes, it could be enitrely turbo-related, as he has put a breather filter on the cam cover crankcase vent which, on the stock setup, would've had a constant vacuum on it...he now has no vacuum on it whatsoever, so his crankcase is likely building up pressure. I'm not saying it's the main cause of the air coming out of the oil filler cap, but I bet you $10 that routing the crankcase vent properly would cause it to drastically reduce the air build-up in the crankcase and cam cover.

not that there's anything wrong with it.

I can't even recall how many folks we've seen come in here and the "other forum" that've asked why their dipstick was popping out, their turbo was smoking, etc.
