Did a compression test:
1st Bank
Cyl 1: 90, 115, 130 Mult cranks max 140
Cyl 2: 100, 120, 140 Mult cranks max 140
Cyl 3: 80, 100, 120 Multiple cranks max at 120
2nd bank
Cyl 4: 95, 120, 145 didnt take max's
Cyl 5: 100, 125, 145
Cyl 6: 100, 125, 150
Cyl 3 doesnt look good.
On to vaccum test:
pretty stable around 19
I then snapped the throttle to 2500rpm, and released.
-vaccum dropped, then slowly came back to 19. Indicates worn rings?
I'm thinking leak down test on #3. Might give a bit more info.
Not looking good for my motor.
