I did u head sto job and have less than 100 miles since then on the truck. I started noticing today that it is louder at idle than it used to be. If you listen closely in the last ten seconds on the video when the camera get by the dages abottle you can here what sounds like a thud noise instead of normal diesel knock. Is something wrong with it or am I just paranoid. I am running rotella T6.

sounds normal... every other good running 6.0/6.4 you listen to sounds like it's got half a dead miss at the intake

I'm a long time Cummins guy, I've owned 15 dodge diesels. When I bought my 6.4 I told them I'd buy it if they'd start up the 30k mile 6.4 right next to it for me. It sounded exactly the same. Sounded like a dead miss through the intake. that was almost 50k miles ago! LOL

thanks for the replies. I am glad to hear I am just paranoid. I am going to try some archoil 9100 in it.
