As you are probably aware oil in the coolant is "NOT A GOOD THING". This is commonly caused by overheating the engine and damaging the head gasket. If you are "lucky" all you have to do is replace ther head gaskets. If you are less than "lucky" you may have a warped or cracked cylinder head. You will know when you remove the heads and examine them and the gaskets.********SPECIAL NOTE******* If you have an automatic transmission the cooler could go bad and put oil into the cooling system. If you are not sure if it is motor oil or trans fluid have the cooler tested.
