Usually the only thing that will cause oil to leak into the cooling system is a cracked block or a leaking head gasket. If you head gasket is leaking you can see or hear air bubbles in the top of the radiator sometimes. If you don't see water in the bottom of the oil pan then you might have a leaking transmission cooler contaminating your coolant.

it could be a crack block, or this rare does he have an oil cooler built in to the radiator? some vehicles with a hitch have it.
