I like my mechanic and respect his work tremendously. However, he didn't report compression numbers when discussing a new engine recently. Curious, I measured it myself.
167, 166, 157, 157 ....at Denver's altitude. It doesn't seem to spell doom.

Changing Plugs
Much Better: $2300
Brakes: pads,disks and labor: $400
Tie-rod end: $200
Alignment: $100
Timing Belt: $1100
Valve Shims: $150
Still has a leaky rear main seal. We're waiting for a clutch or engine to make that a no-brainer.
need: clutch and brake fluid flush, wipers, plugs.

Bad News: scratched cam journal
I took the car in for some chassis work (brakes, alignment) as well as a new timing belt and valve adjustment. By chance the mechanics noticed that the journals were swapped. The exhaust journals (? the part that comes off, not the part cast into the head) were over the intake valves. One of them had a scratch that I don't have a picture of. You can see the scratched shaft and journal in the pix below.
It's dicey, but we decided to try in-shop polishing and re-assembly over putting new headwork on short-block showing its age or going for a different engine just yet.
