So with our 96 f250 we had the problem when we first bought it that the coolant was loaded with oil first thing we did was change the oil cooler thinking that was the problem. We have flushed it I think 3 times at this point and are still getting oil floating around (not nearly as severely however) has it not been flushed enough? The coolant also seems to have copper looking flake in it. I don't want to take it to a shop cuz they ring you dry especially here in Maryland (can't wait to leave this place). There doesn't seem to be any coolant in the oil nor do I see any of the copper flakes in the oil either. The truck seems to run just fine, it's not missing at all.
