Use the search function for heat exchanger and see the dozens of failures - you may be lucky and have a good engine cheap ......

Steve is spot on; oil cooler failures while not common, do happen with these engines. Pull the cooler and have it pressure tested, a new one from a dealer is only about $200, but be sure to always use new O-rings.
