White stuff on oil cap

["Jose Gomez" <gomez.jm@verizon.net>]

HI everyone

Quick question

I've been noticing  kind of a creamy whitish substance on the inside of my
oil cap when I remove it to top of the oil. Is this the tell tale sign of a
leaking head gasket and coolant getting into the oil. My car is going to the
dealer for some oil seals replacement (under warranty @ 98k miles). I was
wondering if there is anything else I should have them check if indeed the
coolant is leaking into the oil.

Thanks

Jose
