I need advice for 750il 1991model. I fixed this one after 2 years of struggleing. No more "check engine " light. Now this one runs very well and I am enjoying the 12 cyliner 290HP power. But it still need some more improvement. I cannot have fresh air while driving. Sometimes have raw gas smell in damp day. and I don't kow to descrive the smell of not clear air. I wonder some exhaust gas is creeping in or not through vent. If I use heater, ther is more a little sweet smell, if I use air conditioner, there is less. Do you think this is a problem from some exhasust manifolder leaking? If so, what to do and how? Thank you for your opinions.
