sound similar to a bearing going out
Has anyone else had a sound similar to a bearing going out, while at idle? It only does it when it's warm and stops as soon as the rpm are brought up off idle. The best I can describe it other than a worn bearing is a "whirring" sound.
Took the truck to the dealer (while it was warm and making the noise). The mechanic started looking at charge tubes for loose connections and didn't find anything. Today they called and said they had contacted Chevrolet and they thought it was the EGR. They have order new parts and gaskets and will call me when they arrive.
Curious if anyone else has experienced this and, if it was in fact the EGR system.

Retired and lovin' it!
