Unhappy weird engine noise, should I worry?
It started a week ago, I recorded last night, nothing to see, just to hear.

It sounds like a bird and metallic noise, hope it is not too bad, ie. detonation or else..

try pulling the supercharger belt off to isolate it then run the truck without it....could be a tensioner pulley or an idler pulley .....

a mechanics stethoscope works wonders for noises like this
