im not too familar w/ the saabs but, where is the "cambox" cover?
The noise it makes dosn't sound deep in the motor thought right at the top middle of the valve cover... I was thinking one of the lifters too and a friend told me it sounds like rod knock but, wouldn't that be deeper in the motor? also, if I took the valve cover off, would I be able to see where it was hitting? therefore which one is bad? id does actually hit the valve cover right?
