I second that opinion, and would go even further. With an unknown
quantity like this, I'd tear it down completely. With it knocking that
badly, I'd also be worried about bent rods, scuffed bores, etc. Or it
could be a dropped valve getting hammered by the piston. Take it
apart and check _everything_.
