Well I don't think it's related to the amount of power you make. I talked to my local dealership's foreman and he said that he has encountered about 20 cars with the problem. He said it isn't a guarantee that any car will have the failure. It makes me think there was a mixed batch of good and bad parts in those early production months maybe. Don't sweat it. He said a lot of the times when it fails, the engine is fine after, although there was one time where the sprocket actually came off and took the head with it (bent valves).

Nice. Good info. I can't seem to find much about that manufacturer on the internet. Do you have a way of identifying the material that the bolts are made from? I am leaning towards aluminum.
