    EGR stack tubes?????

    Does anyone know how the EGR stack tubes are attached to the intake manifold? The one towards the rear of the engine is loose in mine and I am afraid that whatever holds them in place is going to fall off and get sucked into the engine. Thanks, Justin

    Are you referring to the 4.9? Do you mean the tubes as viewed inside of the throttle body when looking down the top of the throttle body with air cleaner cover removed?

    If so, I would like to know from anyone as well. One of mine is loose also.

    Thanks for reply HUF! Since we got three 4.9`s with at least one EGR tube loose, Might be fairly common. Not something i`m worried about but curious, Anyone else?
