Audi 90, fumes inside cabin; oil or exhaust?
 

I have fumes inside my Audi 90. It's a 2.8 V-6 SOHC. I have checked the exhaust and there aren't any leaks that I could see. Thought there might be cause it's loud, but I guess it's all attributed to when I removed one of the catalayic converts when in broke.

The smell and affect of the fumes seems to be worst when decellerating from fast speed or when downshifting. Is it possible that the oil leak I have is getting burned of on a hot part of the car like the exhaust for example and getting intside the cabin? I can't imagine why it would get worst when decellerating. Exhaust catalayic converts are covered with oil. Maybe it gets in through the air intake, where is it any one know? Any one ever have this problem?

alot of times the cam covers leak, and they drip right onto the manifolds.

Thank you for your reply. I think i know where the oil leak is. It's right where the oil radiator (is that the right term) is in the front of the car, next to the coolant radiator. I'm not sure if I know exactly the right term or what it is actually. The leak is at a joint into the oil radiator or where ever the thing in the front next to the coolant radiator is and a tube that goes into it. Oil on the exaust i think causes the smell.

I have new problem now though. When i put car into park or neatral it stalls. I think i can figure it out though. I searched on the internet for what it could be. I think it's the idle control.
