Slant 6 Vibration

Here's my readings:

Cyl 1: 95
Cyl 2: 35-40 (Why God, Why?!!?)
Cyl 3: 115
Cyl 4: 118
Cyl 5: 100
Cyl 6: 100

Gross. Time for some engine work.

On Cyl 2, I got a 5lb jump just using some fogging oil I had on hand

Not enough of a jump to write home about.

when spinning over the engine on Cyl 2 is I can hear either a clicking noise or a degassing noise like a "PSSS" when doing the compression test.

Engine is sick pony. Remove/rebuild.

Not that I want it to be more than needing valve adjustment

It's not that.

I'd rather it be a burnt valve over lower end problems like the cam.

1. It's not the cam.
2. It's not a burnt valve (wouldn't jump with fog oil)
3. You wouldn't actually want what you think you wish, because then you'd go spiff up the head and plop it back on the block, whereupon it would quickly finish off the tired bottom end.
