Hi all: Woe is me! My daughter sent a nasty looking picture of the oil filler cap from her 2001 530i yesterday with a yellowish milky goo all over it. My first thought was "Oh, no, coolant in the oil!" That was the opinion of my local dealer also (I'm in NC, the car is with her in PA). She took it to a local mechanic in PA who thinks it's just "condensation" and needs a "breathing treatment". I'll get more information tonight after she talks with him again but anybody in the cold climates ever heard of this? FYI the CVV and secondary air pump were replaced last year.

Any experiences with similar observations would be greatly appreciated.
