I noticed my battery light came on so when I got home to check it out I found that the belts were barely being turned by the crank. I checked the pulley and saw the bolt was loose and the key was gone. It looks like there was some damage to the inside of the pulley from the crank spinning freely and is a little loose on the crankshaft. Should I just get a new pulley key and just bolt it back on tight or should I get a new pulley? There is no damage to the crank.

 

how was your engine even running with the crank pulley spinning freely on the crank? Your timing belt runs off the crank pulley. If that's not being spun then your cams aren't being spun, which means you may actually have some serious valve/piston damage. Never mind the fact that your plugs couldn't have been firing due to the distributor not turning either.

 

^^ the timing belt runs off a different gear pulley.

Yes.

 

If the pulley is ok then put a new keyway in and tighten the bolt to spec.

I would also look into why it got loose.

You can kit a keyway from the local hardware store where all the nuts and bolts are. I have found one there for the Zex cam and Crower cam gear.

Kinda figured that if one let go the other one would have as well since everything was so sloppily loose.

Looks like the bolt came loose. I did the t-belt 2 years ago. Hopefully that's it.
