We have a 07 Classic 2500HD with the Duramax and we keep hearing a strange noise when the engine is at 1100 to 1300 rpms. Dealer says it is the edge of the Turbo Heat Shield just slightly touching the engine that causes this. The dealer tweeked on the shield with a large screw driver and it stopped for a couple of weeks but came back. Another dealer did the same thing and again short time later the noise is back. Has anyone else had this problem and if so what did you do to get rid of this? The noise is like a very loud cricket and is quite embarassing at times when folks in the campground stare at us.
