Noise coming from transfer case/tranny area

[deacon13]

This is my first post. This noise is driving me crazy. I've been to several different local shops and been told different stuff at each. This sound only happens under throttle and between 1500-2000 rpms in 2wd and 1250-2000 in 4wd.
Any help would be appreciated. I've been told lifters, rocker arms, injectors, wrist pins and total rebuild. Nobody has even considered anything but motor components. If I drive it and hang out the window the sound is under the driver door.

first thing i would do is yank the valve covers and wiggle the rocker arms. likely the ball studs will be severely worn or missing. Could also be the plastic clips.

Is there any fine metal shavings in the oil filter when you separate the pleats?

how many miles on the engine?
