    Q:
    How to replace the PCV Valve Hose on Cadillac STS? Posted by Customer
    A:
    The first step for crankcase ventilation hose replacement requires users to release the lock tab to free the positive crankcase ventilation (PCV) tube connections. The technician should first disconnect both the fresh air PCV tube from its fitting underneath the supercharger inlet duct prior to removing the front segment of the inlet duct assembly. You should disconnect both the PCV fresh air tube at the left camshaft cover and the PCV foul air tube at the PCV orifice fitting on the right camshaft cover. Remove the supercharger assembly together with its PCV foul air tube from the underneath fitting of the supercharger assembly. Begin by attaching the PCV foul air tube to the fitting located under the supercharger assembly before putting in the supercharger assembly. Connect the PCV foul air tube to the PCV orifice fitting on the right camshaft cover while installing the front section of the supercharger inlet duct assembly. The PCV fresh air tube needs to be attached to the left camshaft cover then joined with the fresh air PCV tube to the fitting on the underside of the supercharger inlet duct.
