Homing in on the problem

The background story...

Tonight I finally got a compression gauge that works and ran the test. The result? The "happy" cylinders ran between 100 and 130 PSI. The "unhappy" cylinders (numbers 1 and 8) spiked the gauge, but fell immediately back to zero.

Ugh! Can you say "stuck valve" kids? Great! I knew you could!

Funny thing is that I had the valve cover off the driver's side and, with the engine running, I didn't notice anything unusual. You'd think I would have caught that, wouldn't you? Pretty strange stuff.

In reality, "stuck valve" is pretty generic and could be a bit misleading. I might have dropped a seat, got some carbon jammed in there, bent/jammed a pushrod, or burned a valve. Guess I won't really know until I pull the head(s) and have a look-see.
