oil floating in coolant

Bought a 99 f250 4wd last month, got tired of getting stuck in the winter time. Anyway It doesn't crank good when it is cold so I was checking the gpr. It seems to be working, having a time trying to get to the glow plug wiring to check them.I noticed my coolant looked dirty so I took the cap off the reservoir and there is a very thin layer of oil floating on top. I can shake it around and it will disappear then come right back. Any ideas as what that could be? I hope I didn't buy a lemon, its got 190000 on it.

if its oil in your coolent its your oil cooler.the o rings are bad or your oil cooler is rusted out on the inside. my truck did the same thing and my oil cooler was bad is your truck losing oil? if your injector cups are cracked you will have diesel fuel in your oil. the head gaskets rarely go bad on a 7.3 ill lay money its your oil cooler.

Oil cooler , if its an injector cup you wouldn't be able to make out oil in the Coolant. Go rent a coolant pressure tester from advanced.
