Hey guys, this is my first post on this site after a ton of searching for this issue first. This is on my 2016 silverado 5.3 that has 60,xxx miles on it. The chirping occurs at all engine temps and seems to be coming from the bottom of the engine in the bellhousing area. It's definitely more present down there. I've already removed the serpentine belt and started the engine to rule out any belt, alternator, or tensioner noise. I've also listened to multiple other trucks and don't hear this same noise. Any help would be appreciated!
