Hi..there.. Could well be your Oil Cooler..there's a cooler chamber which is part or attached to the oil filter housing..you'll note a coolant hose leading to it..normally the cooler fails internally and this allows oil to pass into the coolant system..but not the other way round due to the higher pressure the oil system creates..so persuming as far as you tell the engine seems to run fine could exclude the headgasket being at fault..so in that view a new oil cooler will be required and complete flush out as no doubt replacement of rubber hoses if required of the entire coolant system
