You are right. If it is the rear main seal, the oil would be coming from the center of the flywheel and spinning outward.
This is what made me question the GM Tech that was looking at mine. I had oil in the bell housing and around the outer edges of the flywheel but very little oil on the surface area of the flywheel near the shaft. They added dye to see if that would help. After they could not determine exactly where it was coming from, I bouht a UV light and began looking. I also did some research on here and another forum and finally found where someone had uncovered the oil pan gasket leak.
I printed off what I found, took the truck back and showed the info and the oil/dye that I could see and they agreed. He pulled the pan, replaced the gasket and all was well. She is dry as a powder house under there now.
I do not think you need to have it warm. If it is leaking the oil will be there warm or not.
