TTT come on.

stop driving the car or you are gonna dent the headers if it bangs hard enough..:p

you really need some sort of scan tool to tell.... i never heard of any other method..

if you are getting any its really "false Knock" and it should go away after you girnd the Kmember to prevent the banging
