How to service and repair the intake air duct on 2008 Ford F-250 Super Duty?

Start the intake air duct service and repair by taking off the crankcase vent oil separator hose along with its clamp then disposing of both items. The air cleaner outlet pipe detachment from the turbocharger requires a loosening clamp followed by connecting it securely with 5 Nm (44 lb-in) torque upon reinstalling. The clamp should be unfastened and the truck's outlet pipe removed from the air cleaner but tightened to 5 Nm (44 lb-in) throughout installation. To reinstall you must execute the reversal of the removal process while using a fresh clamp for connecting the crankcase vent oil separator.
