I called the dealer this morning, he asked me to take a video of it. He said sounds like they need to look at it, but will know for sure when he has his Techs look at it. He said it could be a solenoid thats part of the vvt. Mine goes away in about 2 seconds. At first I thought it was because the truck sat over a week, but I started it last night and it did the same thing. We will see tonight I guess.

Any update on this yet? Mine 6.2 AT4 is noisy on cold startup, definitely sounds like a lifter noise, truck has 125 miles on it. Was yours noisy at start up as well? Hate to have to take it in already, but from what I have seen online, thats its considered normal if it goes away in 10 minutes.
