This is not normal at all. It can be a real PIA trying to find out what is causing your knock. Here is the list and start ruling them out. I searched off and on for two GD years before number 15 proved to be my problem. Brad

The list is under suicide six and the name is very fitting. www.turbobuick.com/forums/general-turbo-buick-tech/188574-knock-knock.html
