The lessons learned here (for those just reading this thread) are this; just as it takes all of the ingredients to make a cake, it takes all steps to be done correctly to ensure that the job is done properly. One mistake with the cake ingredients and you get soup. One mistake with thread pitch, you end up with near disaster. Check and double check everything yourself.

Thanks. Excellent, excellent bits of wisdom.
As for your oil in the cooling system, remember that the system ran with oil in it for awhile, so there is now an oil film spread throughout all portions of the entire cooilng system: in all the hoses, the heater core, radiator, water jackets, etc. I bet you are seeing this start to break loose and float up. So MB makes a chemical to get rid of the oil. There are two chemicals aactually - one is an oil removal chemical and the other is a citric acid chemical (I assume that one is for rust and hard water scale deposits). I have the oil removal stuff at home so I don't have the MB part number here with me. It was about $12 for the bottle. It is a powder you mix with water, dump it in, run the engine, then drain it. I tried to find the P/N doing a web search but no luck.
It would probably be wise to disconnect the heater core and blow a bunch of water through it and then blow air through it also. There is a fitting that they make that you can attach an air hose to that will enable the blowing out of the heater core. You could probably rig one up easy enough. Me, I am replacing every one of my hoses ($$) since a rubber hose becomes structurally compromised when it is exposed to oil in the cooling system and I don't want a hose blowing up on me.
I'll find the oil removal chemical P/N and post it up here for you.
