My "O" rings went south and I started getting oil in the degas bottle, I think I caught it soon enough and didn't get a lot in the coolant. It takes a lot of time and effort to get the oil out of the cooling system. Simple Green mixed with distilled water, flush with distilled water, repeat. In between green and flushes I ran my truck a few days with the distilled water in it then greened and flush again. Even that didn't get rid of it all, wound up dipping a clean cloth in the degas bottle to get the last of it out.
If you are not 100% sure you've got the oil cooler or other leak under control get it pressure tested as suggested above.
One thing I noticed is the bolts didn't come out of the cooler (where it blots to the engine) easy, I looked at the bolts and it looked like they all bottomed out I made a flat tap and ran that in each hole and also bought new bolts and shortened them a bit to insure the assembly bolted up tight. "O" rings from Ford ($100.00) and I used dow corning "O" ring lubricant - went together really nice...
