Hey guys, I have a 2015 1500 w the 5.7 it’s at 285,000km (177,000 miles) original engine and transmission. Lately I’ve been starting to hear a chirping noise, like a bird but it’s only ever at idle never under load. It’s not coming from the front of the engine u can hear it better in the wheel well or from behind the engine. My truck does have the manifold tick. Anyone had a similar issue or know what im talking about. I’ll try to get a video of it.
