    You can replace the one push-rod but before you do so push in on the valve stem/spring with your thumb and make sure the valve is not stuck in the guide.

    It would be my guess the engine was ran with the valves out of adjustment thus letting the one push-rod jump out of the rocker.

    Would need engine model numbers to post proper valve adjustment procedure and specs.

    One other thing I would check is the valve guide. I have seen them move in and hold the valve open and move out and bend a push rod. You gotta keep the cooling fins clean or the heads will over heat and valve guides will move. I drive the guide out, knurl it and locktite it back in.
