PCV Valve Hose: Service and Repair

Positive Crankcase Ventilation Hose/Pipe/Tube Replacement

Removal Procedure

1. Disconnect the crankcase dirty air hose from the intake manifold.
2. Disconnect the crankcase dirty air hose from the positive crankcase ventilation (PCV) orifice tube.

3. Loosen the throttle body clamps (2).
4. Disconnect the fuel pressure regulator vacuum supply hose from the air cleaner outlet resonator.

5. Remove the 2 resonator to engine bolts (4) from the air cleaner outlet resonator (5).

6. Lift up the front of the air cleaner outlet resonator (2).
7. Disconnect the crankcase clean air hose from the valve cover port.
8. Disconnect the crankcase clean air hose from the air cleaner outlet resonator (2).

Installation Procedure

1. Connect the crankcase clean air hose to the air cleaner outlet resonator (2).
2. Connect the crankcase clean air hose to the valve cover port.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the 2 resonator to engine bolts (4) to the air cleaner outlet resonator (5). Tighten the bolts to 6 Nm (63 lb in).

4. Tighten the throttle body clamps (2). Tighten the clamps to 4 Nm (35 lb in)
5. Connect the fuel pressure regulator vacuum supply hose to the air cleaner outlet resonator.

6. Lubricate the inner diameter of the crankcase ventilation hose.
7. Connect the crankcase dirty air hose to the intake manifold.
8. Connect the crankcase dirty air hose to the PCV orifice tube.
