Mark, that's what I was afraid of. I'm hoping it is the head gasket and not the head itself. I'm probably going to try K&W Block Seal before tearing into things too far - it worked last time (to stop an oil dribble into the coolant, 3+ years ago) so who knows, it could work again! If not I'm in for a $1-$3k repair. Ouch... too bad the rest of the car is pristine, and I'll have to actually fix it... [;-)
