To be fair, I grabbed this engine out of the junkyard with unknown amount of miles on it. Looked clean, no leaks, Also the block was painted black, somebody was in there at some point. The car it came from looked like it was sitting for a decade. When I put the engine in to the car, I did have a hard time getting it going. but once I messed with fuel settings and putting manual glow plugs and new glow plugs in. then I had it running. .. .. pooorly. horrible miss that I dealt with for 4 years until this summer when I tried my hydrolock method to unstick some piston rings. I did manage to get the compression up on the two lowest reading cylinders, engine then ran smoothly.
I haven't done anything yet. been cold and snowy and I don't want to until I get the OM616 put back together and running. https://www.youtube.com/watch?v=LfykoO8tEF8

Its still got life!!!!!
I replaced the starter, and battery, then used two sets of jumper cables. Took a ton of cranking, and stuff, but it finally cracked off.And its colder tonight than it was last Wednesday.

Great news!
So::::: Chalk it up to slow cranking speed? What is the hydrolock method?

with all injectors out, pour oil or some concoction of penetrating oil into the cylinder with lowest compression. replace injector on the cylinder you are treating. use ratchet wrench on crank pulley to rotate engine clockwise until cylinder hydrolocks. then apply some pressure to it. If it eventually finishes its cycle, then you have a VERY bad engine. but if not, then keep rocking the crank back and forth with some force, to ensure oil is getting forced into the piston rings.
*To best get an idea of where the piston would be at, during pouring in fluids, take valve cover off. I'd have the pistons near TDC, and fill fluids until its coming out of injector hole, then let it sit for 30 mins. then finish rotating until piston is past TDC, reinstall injector. I have had mixed results, but worth a try to get rings unstuck, and bring up compression numbers. **After procedure, it is absolutely necessary to purge all cylinders before reinstalling all injectors. so with all injectors out, use starter motor to spin engine several revolutions. This can be very messy to use a beach towel or something to place over injector holes to catch excess oil.

Mercedes OM616 runs awesomely. but won't embark on swap until sunny weather hits.
