    Seems to be the harmonic balancer hitting the plastic shield. All noise
    coming from the shield and not the block. Not bad. Hey, how tight do I
    need to make the bolt holding the balancer? Getting it off took 4 hours and
    about 500 pounds of torque. Don't want to go through that again. When I
    put it back on, I didn't brace the balancer, but slapped the breaker bar
    handle with a sledge a few times. Sufficient?

    You are probably fine. Engine rotation will tighten back to 500.
    I don't remember the numbers for mine anymore but I do remember it
    took a 3/4 inch impact and a full day to get the old one off.
    The starter bump vs. breaker bar would not work.
    I remember putting the new one on with about 10 seconds worth of
    impact from my 1/2 impact.
    You could run to a local library and see if they have a Motors Manual.

    The rotation is in a direction that should loosen it, however, the threads
    are fine and really seem to grip. I don't know.
