Any ideas what this is? 5.3 V8. 135k miles. Its hard to hear while driving but increases with higher rmps. I changed the serpentine.belt, idler pulley and tensioner over the weekend.

Oil level was a quart low, changed regularly with mobil 1. Truck runs normal, no loss of mpg and no leaks from what I can tell. Accleration is normal as well is idle. Not throwing any codes either.
