Thanks for the fast replies! For those who've had a head-gasket blow... is
this much brown goo "normal" after having the gasket replaced?
I'm trying to determine if it's just residue from a incomplete flushing or if that much brown indicates the head gasket is still leaking.
I'm also wondering if I should attempt any fix myself or just resign myself to taking it to my semi-local MB dealer and renting a car while they work on it (I go on a week-long trip leaving tomorrow). If it turns out to be a botched gasket replacement, then I'll want "official" documentation to seek compensation from the first MB dealer.
