I have '95 525iT with 63K miles. Bought it at 58K, and had the radiator and WP replaced at that point in NY. Have driven it to Texas and was cleaning it up this AM, and I thought I'd check the coolant level. Well, the coolant is green, but there are 4-5 half-inch drops of oil on the surface of the coolant. No white smoke out the tailpipe, no milky oil on the dipstick, no nothing else. Anyone seen this? I did add water wetter at 60K, but everything has been fine. Any words of reassurance (or otherwise) greatly appreciated!
