Man s50mc

I might be working with on one of these soon and was just curious if anyone had some good first hand knowledge on these engines. Good, bad, things to watch for, etc. Already found some info from MAN online, but they are more like white papers. Thanks.

Oh yeah. Good little baby MAN engines. I worked on them, pulled pistons out of them, replaced bearings, exhaust valves, fuel pumps, injectors, you name I probably done it. One thing to remember with these and just about all MAN engines is when you get a bell and the exhaust temps on one cylinder does not come up and it still doesn’t even when trying to free up the rack, chances are it is the puncture valve. They are notorious for hanging up. MAN make a great engine IMO
