Is this a 2.4 l duratorq? Done a few oil coolers on these and is a known fault on these. The oil softens and deteriorates the coolant hoses through time and you may have hose problems for some time in the future, if they feel soft and perished then replace. You could try some detergent in the coolant system, run the motor for a day, drain then refill with water and more detergent and do this a few times, it is nigh on impossible to get rid of all the oil but the oil cooler is expensive and you could try a scrappy for a used one, as the previous answer said it may be the gasket itself but the cooler is something worth looking at. Good luck
