Oh man... If I put that gear on backwards, I'd never forgive myself. What a stupid thing to do!! But I was in such a rush trying to get everything done there's a good chance I might have... argh.

Since the chain isn't broken, if I turn the crank pulley by hand until it's at TDC and the cam gear timing dimple is still in the right place would that be a good indicator that my valves are still in good shape, or should I pull the head again anyway?

IF I have bent a valve, how difficult is the replacement process? Is is just replacing the valves, or will the pistons also possibly be damaged? This is getting way beyond where I feel comfortable mechanically... <img src="/forums/images/graemlins/confused.gif" alt="" />
