I'm hoping I found the source(s) of my engine vibration. I removed the front engine dress to get a better look at the balancer, and I came across:
1) someone used the wrong thread fan bolts, stripping it
2) I think someone took out some aggression on the crank pulley as the back as warped.
The question of the damper weight rotating came up as well, so I was on my way to replacing the damper. Now that I have better access to it, can someone help me determine if that is necessary? I was thinking of replacing the pulley and fan bolts and seeing if that made a difference.
It's actually a 69 damper and pulley (on a 1980 engine in a 1967 car, go figure).
