crank pulley?

[ineeda38turbo]

at an idle i here what seems to be a rattle or low end knock, still trying to figure that out, but i did see that it looks like the crank pulley is a bit wabley maybe a bit bent(its pretty small but just barely noticable) is this really bad or not????

Better check the bolts. Maybe it is loose?

The balancer is probably cracked right where it bolts to the snout of the crank. If you remove the balancer bolt, it may fall right off. Don't ask me how I know this. All I did was replace the balancer and key and was good to go. Make sure the keyway is not damaged.
