Any idea guys on what this noise might be? It's loudest in the front of the engine more so near the location of the bank 1 VCT solenoid (passenger side).

The video isn't showing up in either the first post or the one a couple of posts above this one.

That's odd, I'll keep looking into it but I tried it on 3 different platforms and they all worked

I can't say that this is the correct answer, but I had a fuel injector make that type of inconsistent rattling noise when it failed.
Maybe try isolating the sound to one cylinder and popping the injector plug to see if it stops the sound.

It goes away when hot right! Then it could be something in the timing chain, guides or maybe even a phaser, but usually a phaser noise sounds more like a knocking noise. After engine gets hot, first remove the belt and try again to make sure is not belt related if the noise is still there then more than likely something with the timing chains.

The truck doesn't make a single tick while running without the belt installed.

Right now I have it warming up, that rattle noise was present for the first 6 minutes then it stopped, just the cam phaser tick is ongoing and that phaser tick is there all the time.

Might I remind you this truck makes both noises together when cold then the rattle disappears but phaser continues ticking

If the noise goes away with belt remove then is something that the belt turns alternator, tensioner etc .
