Not sure about your engine, but some have an oil cooler in the side of the block which runs in the waterways, so you might have split that.

Hi just a few suggestions what can cause oil mixing with engine coolant

1 cylinder head gasket failure

2 cylinder head craked

3 cylinder head corroded and gasket failure

please note that the oil pressure is greater than the coolant pressure hence it is most probable that oil goes with water and not the contrary.

You better seek proffesional help.

good luck in your findings.
