I've had 2 belts jump that didn't look bad. One was from my own stupidity. This was a carburated 2.2 with an air pump. I noticed the air pump wasn't turning so while the car was running, I pushed something against the belt so as to add a bit of tension and break the pump free. Instantly, the car killed. Never started again after that. I checked the timing belt and sure enough, it had jumped. What happened was the crank was trying to turn the belt and by touching the belt on the other end of the head, I bound the smooth operation for a split second. Just enough to jump the belt. It wasn't much either. The secound one is the 2.5 EFI Sundance I'm driving right now. I bought it as a non running car. The day afer I bought it, I started looking at what could be wrong with it. I checked the belt and it was off one cog. I changed that and still wouldn't start. After a while of not being able to find the problem, I pulled the valve cover off and found 2 followers (rockers) off the cam. They were laying there. The car had a bad tranny also. What I guessed happened, is the tranny was slipping, the previous owner got frustrated trying to get it to go and overrevved it. This caused the followers to jump off the cam. I'm guessing that when the followers jumped, they bound (jammed) something for that split second and the belt jumped. Now I can't say why the followers jumped for sure, whether it was the tranny or what, but Im sure about why the belt jumped. It wouldn't take much of a bind to slip the belt. I leaned that 18 years ago on the 83 2.2. In both cases, The belt may have been a bit loose. I don't remember. I also bought my first GLHS with a timing belt off one cog. That belt had all his teeth. My family seems to like throwing followers off cams. My sister did it twice with 2 different Horizons and my cousin did it to my Dad's 2.5 minivan. In my sisters case the cam and followers were badly worn and she get's mad at her cars and over revs them after they start. I'm not sure what my cousin did to my Dad's van, but when Dad called to tell me they got the van running (after a -28 day caused it to fail) he said it was running rough. Then he said my cousin got it running. Then he said my cousin is a crazy kid. The first thing I thought was "crazy kid"? he over revved it and threw a follower. I was right. I pulled the cover off and there sat the follower. Taking a rest from the rest of his coworkers. LOL
