Hi Again Forum, Ever since I have owned the car, I get a Big cloud of smoke under heavy long acceleration. It will continue to pump up smoke until I release the gas. Highly visable at night in a rear view mirror. The car runs perfectly fine, no smoke on idle or normal driving. This does not happen on my Dads c220 CDI, I can boot that all day and I will only get a puff of smoke on the initial kick down. What I did find from removing the inlet boost pipe was some oil in the manifold. Any advice would be appreciated.
