There is supposed to be side to side play in the rod. As it wears the the play will get worse. Need to find the wear limit spec and put the appropiate feeler gauge inbetween the rod and thrust washers to check it. Big ? is, do you have any up and down play in the crank bearing? And, excessive wear in the wrist pin and it's hole can make the same noise and symptoms you experianced.

there seems to be more wear in the wrist pin. the crank bearings seem fine no play

Could be a crank bearing going bad. Take the stator cover off and grab a hold of the crank and try to rock it up and down.
