Well I was pulling out of work yesterday, minding my own business, driving like usual, when I noticed a slight "whirr" sound from the bay. I stopped and checked it out. The noise is from my crank pulley, and when the motor is idling, it looks off balance, by a lot. it is also making a slap slap slap noise because it hits the TB gaurd. I tried tightening the bolt, but it would No tighten. How often do these just WARP? I will be changing it tomorrow, and not driving in the meantime, but could it be anything else?

cliffs, crank pulley possibly warped, replacing, could it be something else? thanks for the read, info accepted and appreciated.

 

its likley that the crank gear key broke

 

that is a possibility. How on earth would it break though? hmm... Anwyays, i'll be replacing it, and we will see.
