Exactly like Rich in Vancouver, I had the classic original elastomer failure. There had been small coolant losses for a few weeks but there was never an overheating event. It just happened. A lot of the coolant was dumped into the sump. I wasn't many miles from home and managed to limp it back. The coolant/oil mixture formed a viscous black liquid resembling tar.

Was it the 50% OAT that finally broke the elastomer adhesion? I dunno. I replaced it with the Payen elastomer type. No way would I consider the MLS solution.

EDIT: 2004 1.8 Turbo 34,000 miles
