It does start and idle fine. Under throttleup, much smoke is produced, but 
nothing, not even a sound, is escaping from the head gasket area.

After removing the IC and some hoses, I checked the turbo- bearing meltdown
has most likely occurred. I changed the timing belt 1000 miles ago or so,
and I cleaned the IC-2-TB hose at that time. Now, I would expect to see a
thin film of oil inside again, as usual. Nada. Dry as a bone. So something
has interrupted the flow of oil to the turbo bearing.

The bearing was what was making the squealing sounds I'd hear when under boost.

I think the bearing was dislodging before it died completely; that was the 
cause for the strange lost-boost problem that had started to appear. Nail it,
and the sound would go away.

I'll have a more complete report when I get the turbo off the car.
