Another “what is this sound” thread

Doesn’t sound like lifters to me, maybe a broken bolt ? Sounds more prominent on the left side but it’s still pretty faint

Truck has 11k miles, I use 5w30 mobile 1 full synthetic. Oil changed every 5 K (changed from OEM at 1k)

I just took it back from the dealer too smh. They didn’t hear anything of course. It seems to only happen once the truck warms up
