2017 6.7, this has been getting my attention for a little while now, plan on taking it in to have em check it, just curious if I'm alone on this noise. When driving as the truck is generally warming up as you go, when accelerating there is a (not so subtle) whine that I get from under the hood. Can't determine if its engine or trans, but think its engine. Does this until fully warmed up, then I don't notice it any more. Doesn't seem to affect anything other than my nerves...lol. Anyone have anything similar?
