    He probably has a leak in his Charge Air Cooler or a hole in his hoses connected to his Turbo.

    They made the sound on starting up and sometimes on starting out, it was something to do with the variable geometry turbo.

    The DD engines don't have that and don't make the sound. Cascadias with Series 60 did the same thing sound wise.

    Only 14L series 60's from 2004-2009 made that sound. Mine drones a jet sound all day, and it'll rise and drop with boost pressure.

    Yes it's the turbo. A very restrictive POS variable vane garrett turbo. Junk.

    Either the turbo or the CAC hoses... those would be the first two places I looked.
