Almost all of the "EARLY" MB engines required removal of the crankshaft to reseal the rear main! The last gas engine was the M110 engine in 1984, also the cast iron diesel engines upto 1985 required that type of work!
All of the M100 engines require that much work!
Guess they haven't worked on MB's very long, have they??
