Could the vanos have been going through oil starvation as well? or is it normal to be a little dark over there..?
perhaps that little bit of metal got in there during the VCG change and got stuck under that particular cam bearing holder. and if it got stuck in there maybe it would grind the grooves into the came like in your pic and cause it to heat up a lot due to the friction that is not normally there.

The darkened vanos units looks normal to me, check other valve cover gasket replacement threads to see some pics of other people's cars to compare, but from what I recall, both my and my wife's vanos units looked dark like that.
