Ok you can say I’m a new-B to Mercedes, I just bought a 1987 300D 6 cylinders diesel engine with 210,000 miles and I paid $450.00 for it. Now for the problems that I see are oil coming out of the tail pipe like dripping and a lot of blue smoke. Could this be something to do with the crankcase breather system or something worse like a blown head? She still starts right up and I don’t hear any major knocking sounds. I checked the head and it's a 603-016-20-01 so it looks like it has be replaced.
I found this (When the turbo seals go bad, the engine won't smoke on startup. The oil pools in the outlet of the turbo and it's just waiting for you to open the rack and send a dollop of air to the cylinders. Then the oil will immediately be seen in the exhaust) Could it be the turbo or the oil catch can? What can I check for? Please help
