We use preston 50/50 premix compatible with any antifreeze stuff and have no problems. I would think you could get a good radiator flush since it's nothing but soap anyway, but you may have to do it a few times. You'll have to do it inside since you'll have no antifreeze when you put the flush in. Let it get operating temperature and let it run. Flush til clear and do it again. Since you're having to run so much water through the block to flush it you might want to use straight antifreeze and use a tester to make sure you have the right concentration. I'd personally do the whole thing with distilled water to keep the minerals out of my system but you may not have that option.

This is going to sound strange but I had a VT903 Cummins that had the same problem. Cummins told me to mix water and a low sudding detergent like Cascade (dishwasher), run it with your cap off for 10-20 minutes, then drain and flush it with water 3 times. I thought it was pretty silly at the time but it worked well. I think I used one box on a 10 gallon system.

Oil in Coolant
I worked on Porsche engines for 11 years and they also had what was called an oil cooler that was cooled by the engines coolant. The the cooler went bad and leaked oil in the cooler we used (Shout) as it is phosphate free and will not harm any of the metals used in the production of the engine. Yes, Shout that you can by at the grocery store. Fill the system will water and half a bottle of shout then go drive it to reach operating temp. and to make sure it is circulated. Then simply flush. It will take 3 or 4 flushes, the cost is reasonable and it wil leave your system clean to a sparkle. Plus, if the floor you are over it too will get a good cleaning.

Yes, a soap that will break down oil and suspend it or other grease cutting brands will work. Use one that does not suds up as you will be fighting bubbles for weeks!!! The above ideas are good ones too. The key is to really flush the heck out of it when down as to remove all traces of soap and oil. May want to flush with soap twice just to be sure.
I would use just tap water for the soap flush treatments as so much of it will be used. When completly clean of soap and oil, the re-flush with 100% distilled water 4 times (about 15 gallons @ $1.00/gallon). I would then use the factory Ford antifreeze from the dealer at about $10.00/gallon and get back to a 50/50% concentration.
How about a coolant filter. I have one from dieselsite.com and pics are in my gallery of what it filters out. It will catch any sediment as well as oily residue that may be left over. The pics in my gallery are worth a 1,000 words on why coolant filters are a great mod to utilize.
Good luck and if you did the repair correctly, you will be fine from this point on.

I think Cascade because of the low sudsing quality. Ever put dawn in a dishwasher?? My daughter did and the impeller/pump caused a huge bubble machine. I've used cascade on driveways to remove motor oil and it works really great. I'd have never thought in a motor/radiator. I know what I'll be doing my next radiator flush with for sure.

well we use commercial degreaser at work. it encapsulates the grease and gets it out pretty quick. but you will never get it all out. i have had some i have flushed for hours, and they come back oily again. good luck. gold coolant loves mixing with oil and they make one heck of a lubricant when they mix!!!

I've used chemical flushes, simple green and liquid dish detergent (sunlight). I find the dish detergent works best, followed by the simple green, and the chemical flushes might as well just be poured in the trash IMO. I prefer to remove and send the radiator to be flushed, and I'll replace any rubber hose that's gone bad, aswell as the degas bottle cap. I normally flush them about 4 or 5 times, depending on the degree of failure.
