Im going back together with a top end rebuild, new pistons rings gaskets plugs. But when I tork the rocker box on and kick it over theres a loud knock, ive adjusted the vaulves several times and the knock persists. It knocks right before the left cylnder exughst stroke, but i cant determin if the knock is on either side. Im stumped, please help
