Usually overheating issues are caused by a leak or stuck closed thermostat. My mind runs to the worst because of the multiple problems, and usually when one point of failure can cause all the noticed problems, that seems to be what it is normally.
The oil is black and dirty, no foam or "chocolate milk" LOL and the antifreeze was still nice and green. We had no heat in the cab either, so my first thought is the thermostat. We will play with it some more soon, and start figuring it all out.
