Add me to the list of '05 MINI owners with the cursed engine mount leak! I started leaving a trail of gunk yesterday! The dealer told me to drive the thing in for repair.That means 3 hours to Phx...and I hope it's safe to drive that long with this problem!
I'm glad someone hear posted photos of what the leak looked like. The owner's manual doesn't mention what the name of the particular thing that is leaking is, so describing it over the phone was a novel experience!
