Hi Guys, I had my 02 duramax for a couple months now and seems like there is a (raddle) not a knock or tick when I am sitting in the cab of the truck at about 1500-2000rpms at light acceleration or cruising at those rpms. I poped the hood and can't here anything from the outside but when your in it driving it is there, after the truck warms up it seem to go away but you can still kinda here it then but not 1/2 as bad when the truck is cold. The performance of the truck is the same. Under hard accelleration the raddle gos away. what do you guys think? Thanks for any help
