Ok so I noticed a metallic "clang" from the front of my SD at idle, goes away at anything above. I looked at the crank pulley because I had a similar noise a few years ago and it turned out to be loose crank pulley bolts.. I notice the pulley is wobbling a bit.

So today I try to tighten down the obvious, as I thought, loose bolts. I only found 2 that moved when I tried to tighten them. I still have the wobble and the noise it getting worse. I took a vid but lost it somehow.

I am thinking that my balancer/damper got damaged when I lost several pulley bolts a few years ago. It perhaps took this long to reach it's failure point.

So crank pulley wobble = bad balancer?
