Hi I have had a burning smell in my cabin for a while now. I took it in and was told it was my passenger turbo. I just had them replaced 2 years ago! Their is no smoke coming from my exhaust and not a noticeable drop in oil level. The smell and smoke is coming from my passenger side right near the turbo. The lines coming from turbo have oil residue on them and surrounding areas do as well as the tranny has oil dripped on it. I feel that the oil is coming from above and dripping onto a hot turbo or something and burning off. I have read several places that the cam seals leak and could leak down onto other hot parts and burn off. Also, is it even possible for the turbos to leak externally, but function fine?
