This has been a covered issue but can’t find the exact issue been having. I️ have an 05 lly that has been getting a knock. It honestly sounds to me like rod knock though I’ve heard that’s rare on duramaxs. I️ know for sure it’s not a broken crank. The part that makes me think it’s a rod is is I️ can hear this knock at idle where most people I’ve read only hear injector knock at higher rpm. My balance rates are out of wack a bit but can this cause it to knock like that through the rpm range? Don’t have any back smoke or haze at idle or under acceleration(another reason thinking rod). Hoping to god I don’t have to do a bottom end. I️ have checked the clips at the injectors and all look good. Also checked the rub spot by the alternator bravket and didn’t see any issues. I’ve ran a small bottle of hotshot diesel extreme in the tank trying to get the injector rates under control and did a hot soak with sea foam but didn’t get much change. The pic is my current balance rates after the hot soak with new fuel Filter and the injector cleaner in the tank. The truck is 100% stock mechanicaly. I️ just got the truck about 2 weeks ago. It ran fine with no knock at all. The knock is a new development within that last couple days. It was a theft recovery so I️ don’t know any history on the truck. Anyone have any input or advice to try? I’m all ears.
