Need to get some information so I might be able to assist. When you have this knocking noise, is it louder cold or hot or same both ways? Also, if you put the vehicle into gear, does it knock louder or quieter at similar idle speed (make sure brake is on, vehicle blocked)? When driving, does it knock louder on an accel or a decel, or when you put the vehicle in neutral and coast? Have you tried a mechanic's stethoscope to try and isolate it yet?
