Possible OM642 rebuild
Seeing that a used OM642 costs nearly $10k, I'll probably be rebuilding my engine. Has anybody taken on this task? What's involved in it? Will a speedshop/machine shop be able handle the machining if needed. If not, why not? I've worked on American V8 engines, including complete tear down and reassembly--so, I do have a basic understanding of components. What are the hurdles I'm looking at with a modern MB Diesel. Will I need to get things reprogrammed after the rebuild?

I went to the MB dealership parts dept. today to see if they had a service manual or exploded view/diagram or assembly manual of some sort for the OM642. Unfortunately, the answer was no.

I am surprised no answers. Perhaps post to the diesel forum? Lots of knowledge there as well. I’d be interested to know if it can be rebuilt as well? What is/was the issue that you need to rebuild?

Go to the Sprinter forums. Then report back what you find.

I don't recall any, I stumble across them when I search, world wide web, for specific issues with our engine. Sprinters are the ones with the highest mileage and most experience.
