Thanks for the reply, yea I have heard the possibilities of all the problems that it could be. I am not sure if it is the infamous timing chain problem though, because sometimes the knock doesn't go away, it does it until it is turned off, but then there are times that it doesn't do it at all. well thanks again and if you have any other ideas about what it could be, please inform me.
