Having experience of looking after a Mercedes OM636 I can say that they are also excellent engines. I know of one that is now 35 years old and has had nothing other than normal servicing. Not even the injectors have been out. Runs as smooth as the day it was made.
Similar story to a friend who had a 1968 11 ton Hillyard with an OM636, which he bought in 1972, and still owned right up until he passed away a couple of years ago. Other than having some hoses renewed at some stage, I don't recall the engine ever needed a spanner laid on it, and it still had its original paint and looked like new too!
