Hey my harmonic balance is shot. At idle the pulley is wobbling like no other. But my question is could this excessive wobble make a sort of knocking noise also. I just noticed it severely today on the way home. I thought oh great spun bearing...but the sound would go away. So I'm wondering if the pulley could be making this noise.
When I got home I would look at the pulley and have my roommate rev the
engine a little and I could see the pulley flexing/wobbling and when it did that I could hear the knocking noise. And sometimes if you revved it the pulley would straighten its self out and it wouldn't make the knocking noise.
I thought I have ran across somewhere on here where someone said the harmonic balancer/pulley could possibly be mistaken for a rod knock or other engine noise.
If you have any insight on this please let me know. I guess I go to get a new crank pulley anyway but I'd like to have the ease of mind that hopefully I didn't spin a rod bearing. I would cry cause this is my DD and I don't wanna have to tear apart the whole thing like I just did with my 300zx.
Thanks
