The most common cause of coolant in the oil and oil in the coolant is the oil cooler gasket on the drivers side of the engine. It is a plastic gasket with rubber seals embedded into it. See the directions below. The motor will have to be jacked up on the drivers side and the drivers motor mount will have to be removed to replace the gasket for the oil cooler.
