Knocking and black smoke...
I have a 2003 LB7 motor that has a knock in the #7 or 8 cylinder, and it is blowing black smoke, still runs good, but knocks. I pulled the pan on the motor there are no metal shavings whatsoever in the pan, Not sure what it is? I was told if it was an injector tip its possible but im stumped? any ideas???
