Re: My 1968 C-20 Golden Anniversary Project
Compression test and leak test again with better equipment (to screw).
Comression (psi) /leak test (%) ok:
1: 180/17%
2: 190/42%
3: 190/42%
4: 180/28%
5: 180/25%
6; 190/25%
7: 180/22%
8: 180/22%
Found ot that the position of the piston is very important for leak test. Sometimes you could turn the pushrod with the fingers, the valves are still open a crack and you get more percentages, see cylinder 2 e.g.
