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

  • always a Ford lover on every video. If the Duramax is go shitty, why care so much about it to post?

  • that sound is normal with most isuzu products

  • leaking injector probably caused a hole in one of the pistons
