Smoke is definitely BLUE. Left car w/independent MB Tech/Wrench several days ago; 'told him I suspect valve guide seals. He says he can't find any prob. w/valve guides & seals. He has also adjusted valves (adjusted last time 1 yr., 4 kmi ago) and checked compression, glow sys. and injectors and found all OK. He mentioned possible prob. w/injection pump. Car runs beautifully after about five min after 1st start of day. How can IP prob. cause oil burning, especially only for 1st five min.?
