Check for an engine oil heat exchanger in the radiator or a stand alone unit that will have coolant and engine pressure oil hoses/tubes running to and from it. These are a common way the factory uses to heat the oil in-order to reduce engine warm up time for meeting emissions standards. A leak in one of these exchangers would be engine pressure oil getting into the coolant while little, if any, coolant would get into the oil.
