Was a bit concerned bout that.When you pull the damper, take a dial indicator and rotate the crank to see if it's bent. That has happened before...
To be a bit optimistic, the GM balancer isn't showing really near the movement at all unless I get at the right angle and see that rubber's uneveness waving in and out.. If I wasn't obsessing over this, it for sure would look perfect at a normal glance from above the bay......
I don't have any dial indicators or any gauges of the sort for that matter. Guess it's time to grab one.
I was coming on here to mention something odd.
After I installed the damper Saturday, I fired up the truck and went into town...Everything seemed fine...
Came home and parked in my driveway facing up. A couple/few hours later I went to pull it into the garage and had an usually long crank before it started. It's never done that...
Anyway, it's been in the garage since Saturday night, flat parked obviously, and I just went to start it up to back it out and I had another long crank before it fired up. Like 2.5 seconds...
not sure what that's about..
maybe I'll put a timing light on it...??
