Richard, I found a loose clamp at a connection near a radiator inlet that I've been blaming on the coolant loss. I haven't pulled the head yet, so I can't completely rule out a head gasket problem.
Yeah, with an EGT of 1080 I was surprised to find aluminum deposits on the plug. I've only had the car a few months, so I don't know when, if ever, the EGT gauges haave been calibrated.
