How to diagnose OM617 shaking at idle?

Okay, so I checked the valve lash, and all the valves passed, maybe a little on the loose side but I've been told loose is better than tight. I fiddled with the rack damper bolt a little and that seemed to smooth things out a bit. It ran nicely this morning, but by the time I got to work it was shaking again.

So apparently it idles worse hot. Any ideas?
