So I decided I would do a leak-down test. I know, the results might be different if the engine was hot and fully oiled, but I did it anyway.

Test psi was 100psi and I did test both at top stroke and bottom of each cylinder.

Results were:

Cyl 1 top - 90%, bottom - 92%
Cyl 2 top - 84%, bottom - 88%
Cyl 3 top - 84%, bottom - 80%
Cyl 4 top - 90%, bottom - 90%
Cyl 5 top - 82%, bottom - 80%
Cyl 6 top - 86%, bottom - 84%
Cyl 7 top - 96%, bottom - 94%
Cyl 8 top - 90%, bottom - 90%

Now this was a long sitting, dry engine. Given the results I am going to replace the valve guide seals and hope for the best. If you think I'm screwing up let me know.

Looking at how clean the valley is on that one, and your cold test results, I'd say it's a runner.
