Its not the best video but if you turn it up and listen you can hear the knock, and then it will kinda go away because i give it gas an then let off an it comes back. not sure what it could be, its leaking tranny fluid from the flywheel cover. I scanned it an got a code for the fuel pressure regulator circuit and glow plug control circuit and low engine boost. anyone can help thad be great thanks.
im having the same issue with my 03 lb7. did you figure out the issue?

depending on the year, some duramax's had a issue with the pistons spliting in half cuz they couldnt handle their own compression

leaking injector probably caused a hole in one of the pistons
