Hi
I recently got a Om 616 engine from another forum member and I'm researching different rebuild options, I want to rebuild the engine and take the engine on the car and rebuild it to and make a diesel generator with some particular design features.

So now i have the engine mount in a homemade server rack/ engine mount inside my shed, the engine is almost all apart the pistons seems to be good as well as the head, the cylinders look worn but not to bad, I haven't accurate measure anything yet.

I was reading different threads in the forum and I would like to take a more DIY rebuild path not just take the engine to a shop and have it rebuild, there is different options to follow and I will appreciate any advice and help.

Re bore the cylinders to a bigger size, and put some OM617 pistons, I was reading in the Haynes manual that the OM 617 has a bigger bore 91mm and the OM 616 90.0mm.

Change the cylinder sleeves or liners and keep the same pistons with new rings.

That is like the central question, besides that many off the other parts are easy to change and no so expensive, valve guides, bearings, seals gaskets, etc.

The engine fits very well in the back seat, I will put more pictures as soon as I clean up my shed and start whit the work
