Removal Procedure
- Remove the intake manifold. Refer to Intake Manifold Replacement.
- Disconnect the electrical connector from the oil pressure sensor.
- Remove the valve lifter oil manifold bolts (2).
- Remove the valve lifter oil manifold (1).
- Do not lift the manifold by the electrical lead frame.
- Identify the 8 gasket retaining strap locations (1-8).
- Using a wire-cutter type tool, cut the 8 retaining straps of the outer gasket.
- Remove the outer gasket (1) from the manifold.
Important: Do not allow dirt or debris to enter the oil passages of the manifold. Plug as required.
Important: Remove only the outer gasket from the manifold. Do not disassemble any of the internal components of the manifold in an attempt to remove the 8 inner sealing gaskets. If the inner gaskets are cut or damaged, replace the manifold as an assembly. Only use a wire-cutter type tool in order to minimize the amount of debris. Do not use a rotary-type cutting tool on the retaining straps.
Installation Procedure
- Install the service gasket (1) onto the manifold.
- Install the manifold (2) with gasket.
- Install the manifold bolts (1).
- Connect the electrical connector to the oil pressure sensor.
- Install the intake manifold. Refer to Intake Manifold Replacement .
Important:
• All gasket surfaces should be free of oil or other foreign material during assembly. • Do not allow dirt or debris to enter the manifold. Plug as required.
Notice: Refer to Fastener Notice in the Preface section.
Tighten
Tighten the manifold bolts to 25 N·m (18 lb ft).
