I have had my engine stuff up at max revs, and as it looks the front crank pulley is turning when I crank it and the cam belt doesnt turn. So from this I think I have somehow managed to break the key out of the keyway for the timing belt drive gear. I have heard of people wrecking the keyway for the main pulley but not this sucker.

Has anyone ever heard of this?

I am hoping my crank and some of my valves arnt damaged or else I will be pissed off.
