WARNING:
- Diesel fuel and diesel fuel vapor is flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.
- The fuel system (fuel pump, high pressure fuel lines, fuel rail, injectors) contain very high pressure fuel. To avoid the risk of personal injury or fire:
- Do not loosen any fittings while the engine is running.
- Wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system to allow pressure to decrease to a lower level.
- Wear appropriate eye protection and protective equipment as high-pressure fuel spray can penetrate the skin.
- Never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.
CAUTION:
Use appropriate clean care kit caps to protect the engine from contaminants.
- Remove the intake manifold. Refer to Removal and Installation .
- Remove the rail to rail and pump to rail high pressure fuel lines. Refer to Removal and Installation and Removal and Installation .
- Remove the fuel injectors. Refer to Removal and Installation (CYLINDER 1 and CYLINDER 3) , Removal and Installation (CYLINDER 2 and CYLINDER 4) , Removal and Installation (CYLINDER 5 and CYLINDER 7) and Removal and Installation (CYLINDER 6 and CYLINDER 8) .
- Remove the fuel rail. Refer to Removal and Installation .
- Disconnect the harness connector from the camshaft position sensor (bank 1). Refer to Exploded View .
- Loosen the rocker cover bolts (A) and remove the rocker cover [bank 1 (2)].NOTE:
- Rocker cover bolts are captured bolts and should not be removed.
- Place the rocker cover on a clean surface to reduce the possibility of contaminating the gasket groove with debris or oil.

Inspection After Removal
WARNING:
- To avoid the risk of injury to eyes and skin, when using caustic solutions, solvents, acids, or alkaline materials follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Avoid spilling onto a hot exhaust manifold which can cause a fire.
- Some solvents are flammable and toxic. Read and follow the manufacturer's instructions before using.
- When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:
- Do not exceed 207 kPa (2.111 kg/cm 2 , 30 psi).
- Wear appropriate eye protection and protective clothing including gloves.
- Clean the rocker cover with solvent. Dry with compressed air.
- Remove any gasket residue from the rocker cover.
- Inspect the rocker cover for cracks or other damage. Replace the rocker cover if any damage is found.
- Inspect the heat shield on the rocker cover (bank 1). Replace the heat shield if damage is found.
- Use a suitable tool to remove any gasket residue from the sealing surfaces on the cylinder heads and front cover. Use care to not scratch the sealing surfaces of the cylinder heads or front cover.
- Inspect the following for damage:
- Cylinder heads (bank 1)
- Front cover
- Camshaft position sensor in (bank 1) rocker cover.
- Check that the dowel (A) in the rocker cover (bank 1) is installed in the cover and has not stuck in the cylinder head (bank 1).
Installation
- Install a new rocker cover gasket (2) or into the rocker cover (3) grooves.CAUTION:
- Do note reuse rocker cover gasket.
- Do not lubricate the gasket.

- Clean the joint sealing surfaces with isopropyl alcohol and a lint-free towel. After surface is clean, prepare it with Bonderite M-NT 5700 or equivalent wipe. Allow surface to dry before applying sealant.
- Apply a 9 mm (0.35 in) diameter (D) drop of Loctite 5900 RTV or equivalent sealant (C) to the joints (A) and (B) at the cylinder head (2) and front cover (1).NOTE:
- The rocker cover must be installed within 5 minutes of applying sealant. Final torque must be completed within 30 minutes of sealant application.
- The mating surface for the rocker cover must be clean and free of oil and debris.
- Install the rocker cover (bank 1) and hand-tighten the bolts and then tighten the bolts in the sequence shown.
