A friends 71 240z has had two rocker arms come completely off. My question is, what is the best way to get them back on? Does the camshaft have to be removed? There was no detrimental damage and everything is stock.

Thanks Chase

From memory... Loosen the locking nut that you normally loosen during a valve adjustment and unscrew it to the top. Turn the ball-headed bolt all the way down. Use a pry bar or big screw driver to compress the valve spring enough for you to slip the rocker back in place. Pry against the rough cam surface and be very careful of the polished lobes. And watch your fingers! Somebody should proof read this before you try it.
