Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
- Disconnect plastic tube assembly (2) from the crankcase breather on valve mechanism cover (7). Refer to Disassembly and Assembly, "Crankcase Breather - Remove" for the correct procedure.
- Remove bolt (3) from clip for tube assembly (4).
- Remove bolt (5) from clip for tube assembly (6).
- Remove bolt (8) and position pressure sensor manifold (1) away from valve mechanism cover (7).
- Remove bolts (9) from valve mechanism cover (7).
- Remove valve mechanism cover (7) from the cylinder head.
Note: Remove the valve mechanism cover vertically in order to avoid damage to the electronic unit injectors.

Note: Install the valve mechanism cover vertically in order to avoid damage to the electronic unit injectors.
- Position valve mechanism cover (7) onto cylinder head (13). Ensure that harness assemblies (12) are not trapped during the assembly procedure.
- Install bolts (9).
- Tighten bolts (9) in the numerical sequence that is shown in Illustration 6. Tighten the bolts to a torque of
9 N·m (79 lb in) .Repeat Step 6 in order to ensure correct torque.
- Position pressure sensor manifold (1) onto inlet elbow. Loosely install bolt (8).
- Install bolt (3) to clip for tube assembly (4).
- Install bolt (5) to clip for tube assembly (6).
- Tighten bolt (8) to a torque of
22 N·m (195 lb in) . - Tighten bolt (3) and bolt (5) to a torque of
22 N·m (195 lb in) . - Connect plastic tube assembly (2) to the crankcase breather on valve mechanism cover (7). Refer to Disassembly and Assembly, "Crankcase Breather - Remove" for the correct procedure.
