only time i've seen oil in the coolent is when there was an oil cooler involved that become faulty....
otherwise coolent in the oil would mean a head gasket...check your oil cap or dipstick for a milky brownish color...
I've seen LIM gaskets leak oil into the coolant often enough. And vice versa plenty of times, too.
