More info...
Ok. I ran a small scerwdriver around the crank and felt a tiny bit of key right next to the timing gear. I aligned the balancer as good as I could with the key and installed it. I then reassembled the rest of the parts and tried to start it. No start. I then started thinking that the key was sheared but I still thought I felt it so I called napa.They only sell the key with a new balancer but I went there to look at it. It was about 1 3/8 inches long. Then I thought for sure it was broke so I got the dimentions and bought the closest one I could find at a hardware store. I then removed the front engine cover to install the new key and found the timing chain in half and the crank gear split down the middle right at the key. The chain was stuck behind the crank gear forcing it forward and tilting the key up through the crank gear. The chain damper was also in a few pieces. The engine turned over fine though, not like there was no compression on the cyls or anything so I dont think any valves are bent.
The engine has 180k miles on it but the teeth did not look too worn.
Very strange. I think the engine died after the crank sensor and teeth were ruined. Any Ideas as to what may have caused this? I still think it was the belt falling off. Maybe the chain broke first. Who knows...
