^^^Yes, I have the fan delete mod. And thanks, c1apton and Rob . . I stopped worrying so much about it for a few hours today, and yes, the same thoughts hit me . . could be anti-corrosion coating from the new radiator. I also took samples of the oil in the coolant against an oil sample off the dipstick, and the color wasn't exactly the same. I also opened up the oil filter canister to make sure I didn't have coolant mixed in. Then something else hit me- Water Wetter tends to look like droplets of oil, particularly when using non-BMW brand coolant; I use Zerex GO-5. I take it that's where you were going with that question, Rooz? I'm thinking it's gotta be one of those two answers, so I'm not gonna sweat it until & unless I start seeing other symptoms.
Oh yea, c1apton, I did the Bar's Leaks thing back when the radiator was replaced, as per your suggestion
Now I'm gonna get back to the original reason why I went under the hood this morning- to check the belt tensioners . . I'm getting a little whine coinciding w/ the rpms, I figure the bearings are going on something down there. If not one thing, it's another
