I had oil in my cooling system. I flushed it out and changed my oil at the same time. Now there is oil in the cooling system again and it is cleaner oil. It does not over heat or run any differnt The car has 200,000 miles, what should I get fixed and how hard is it to do it your self. What would happen if I just left it alone? I had the water pump replaced less then a year ago.

Is it engine oil or tranny fluid? You did not say what vehicle this is, engine size or year, But if the tranny lines screw into the radiator, could be tranny fluid, if it's engine oil. It's either a bad head gasket, or cracked block. Do a cooling system pressure test, follw directions for detecting head gasket leak, If tranny cooler lines are going to the radiator, replace the radiator! The oil tank in the radiator is cracked.
