Here across the ocean I've seen quite a few OM617 diesel swaps on XJs and MJs. Usually with a few engine upgrades to give it a bit more oomph
I've seen an OM617 swap on this forum as well, but can't for the life of me remember who it was doing the swap. I'm sure you can find it with google. The swap itself shouldn't be that hard, especially with the adaptors etc. being offered these days.
