  I have lost oil pressure three times and every time the rotors will overheat and expand and seize on the side housings and there has been no bearing damage and in fact I used the main bearing over again, the last time when an oil line blew I even restarted the engine three times and ran it till it seized again to milk all I could out of it to get me to a better landing spot and still there was no bearing damage.
 It will be interesting to see if Rusty's engine shows the same.

Rusty,
I would think that the bearings would be ruined while running without oil, but you'll know more when you tear it down for inspection.
 
It certainly could have been much worse.  At least you and the plane can be reused.
