There is the possibility of piston slap or the cam has worn through the hard surface. UK Fords used to suffer from that but that was probably before you were born
Not a great deal you can do about either without ripping it apart bt an engine stethoscope may help narrow it down (cf ferret.. hosepipe, barney..screwdriver)
