Well. timing chain and rails.. I wouldnt expect to see a black cloud unless it's a Diesel. and unless someone converted it. 300E's are Gassers.do you mean a 300D? at any rate if it's a gasser spark plugs wires rotor. check coolant, oil Trans fluid etc if it's a diesel. filters and most of the list above
