Is this noise normal??

To preface I've never owned a V8 before. Always small trucks: '81 22R standard, '90 3.0L Ex Cab, '98 3.4L Tacoma... And now a 2019 Tundra TRD Pro 5.7L. I like to think I know a good noise from a bad one -- I've blown head gaskets, CV joints, etc.

Anyway, since I've owned my TRD Pro it's made this noise (see video)... A sort of clack clack w/ the revolution of the motor. It only does it at around 1400 rpm when the truck is more or less coasting up a mild hill. I really notice it when I'm in 4 Low... Maybe because I always wheel w the windows down, idk. But now that I've noticed it, I can't stop noticing it... And it's driving me crazy.

Is it normal? Is it the timing chain? I kinda thought a seal, but I can't hear it if I give it more juice... Of if the rpms are fast/slow.

If that doesn't work, I'll upload via drive.

Thanks guys!

 

Video works, but I can't identify the issue. Good luck OP!

 

I have done a bit of 4 lo wheeling in my truck and it has never sounded like that, I don't think that is normal. No idea what would be causing that though. Good luck diagnosing it.
