OK, I am reporting back. This is starting to sound like a Gus episode.

Just to summarize, I'm chasing a rough idle and discovered low compression on no.8. Leak down indicated exhaust valve.

Pulled the head and no. 8 exhaust valve. The valve was very slightly burned. My mechanic touched up the valve and the seat. Then we found that the lifter had a stuck check valve. We installed a new lifter and checked clearance. We thought problem was solved. Reinstalled head.

Started up this afternoon. Still had lifter noise and the miss. Pretty much same as before.
Ran the engine for a few minutes and still noisy with no smoothing out. ugh..

Checked the compression on No. 8 and it was almost 100.

Maybe some of the engine guys can point me in the right direction to go from here. I know where the nearest watering hole is....

Thanks guys,
Mark
