They don't just bend back. I'd take it in before your motor is shot. You'll need to replace the bent valve ASAP if indeed that is the problem. If the problem comes and goes, it's probably not a bent valve.

that was one long run-on sentence, that made no sense, why would you "step on it" if you know the car is cold and is making noises due to damage ? are you trying to kill the engine ?

should have fixed it right when the tensioner snapped

sorry for the run on sentence its from lack of sleep, any way i don't think the valve is bent bad due to the teeth were off by three or four from original position and only cylinder one was effected (at least thats wat i was told)

Off by ONE tooth will hose your timing. Plus, like I said, once a valve is bent, it's bent. It will not "fix itself" sometime later. Also, if it's bent valves causing the issue, you will have trouble all the time, not intermittently. This may be beyond you, but do this:

Take a blower attachment for a air compressor and run a few psi into the #1 cyl through the spark plug hole. If you hear it through the tail pipe it's an exhaust valve, if you hear it through the intake (remove the filter) , it's an intake valve, and if you hear it through the oil fill cap (remove the cap) it's bad rings.

Try that on every cylinder and it will tell you what is bent in each one. You probably bent more than one if not all slightly by now.
