I do not think that an engine that is too rich and overcompressed would get hot while running.
Franchi, if you really want to see a diesel run hot, going overcompressed is the way to do it. A lean setting will run a bit hotter than normal, but ultimately the misfire will cause it to be self-limiting, so a lean diesel won't get as stinking hot as a lean glow.
As Mr Cox says, having it misfiring and overcompressed at the same time doesn't make a lot of sense. I've seen plenty of misfiring diesels and quite a few overcompressed ones, but never the two things together. I also don't think I've ever seen a misfiring diesel get really hot.
