    Harmonic Balancer wobble

    I noticed the other day that my bottom pulley (Harmonic balancer) has a little wobble. Is this normal for ls2's ? I'll post a video when I get home. I don't feel any vibration like some G8 guys have reported on the other boards. Do I need anything besides a wrench to torque down the bolt?

    Normal to some extent on all engines. As long as the belt is being driven properly/freely and not being damaged. I seem to recall on G8's it was a casting issue.If it's slight, you'll be allright. If it's wobbling like Michael J. Fox shakin' then there is a problem.

    I wouldn't torque anything beyond spec as I recall that is a TTY bolt. Meaning it stretches as you add torque, like your headbolts.
