- Assemble the camshaft cover (2) and NEW gaskets (5). Ensure that each gasket is located in the correct retaining groove in the camshaft cover.
- Ensure proper use of room temperature vulcanizing (RTV) sealant. Refer to Use of Room Temperature Vulcanizing (RTV) and Anaerobic Sealant
- Add a 14 mm bead of sealant at the right and left T-joint where the front cover meets the cylinder head and at the rear of the camshaft cover at the right and left T-joint where the vacuum pump bolts on. Refer to Adhesives, Fluids, Lubricants, and Sealers (LCV) .
- Install the washer (3) with bolt (4).
- Install the cover on the cylinder head and hand start the bolts (1, 4).
- Tighten the camshaft cover bolts in sequence to 10 N.m (89 lb in).
- Inspect the vacuum pump seal. Refer to Camshaft Cover Cleaning and Inspection (LCV) .
- Install a NEW vacuum pump assembly gasket (3) on the vacuum pump assembly (2).
- Install the vacuum pump assembly (2) and bolts (1). Tighten the bolts to 10 N.m (89 lb in).
- Install the camshaft position actuator control solenoid valves (2) and bolts (1). Tighten the bolts to 10 N.m (89 lb in).
- Inspect the inside of the ignition coil rubber boot for a thin, even coat of grease. If there is no grease present or additional grease is necessary, complete the following procedure:
- Apply a thin coating of dielectric grease evenly to the inside of the ignition coil rubber boot, up to a depth of 15 mm from the end of the boot. Refer to Adhesives, Fluids, Lubricants, and Sealers (LCV) .
- Remove any excess grease from around the end of the boot, and ensure there is not an excessive amount within the boot.
- Install the ignition coils (2) and bolts (1). Tighten the bolt to 10 N.m (89 lb in).
- Install the front lift bracket (2).
- Install the front lift bracket bolts (1) and tighten to 25 N.m (18 lb ft).
- Install the rear lift bracket (1).
- Install the rear lift bracket bolts (2) and tighten to 25 N.m (18 lb ft).
- Install the camshaft cover heat shield (2) and bolts (1). Tighten the bolts to 10 N.m (89 lb in).
- Inspect the oil level indicator O-ring seals (4) and replace if necessary.
- Lubricate the O-ring seals (4) with engine oil and install the oil level indicator (3).
- Inspect the O-ring (3) on the engine coolant air bleed pipe. Replace if necessary. Install the engine coolant air bleed pipe (2).
- Install the pipe bolt (1) and tighten to 10 N.m (89 lb in).
- Install the PCV hose assembly (1) at the quick-connect fittings.
NOTE:
Ensure all camshaft cover gaskets are replaced, including the inner gaskets.
CAUTION:
Refer to Fastener Caution .
NOTE:
Ensure the vacuum pump seal does not need to be replaced, and the sealing surface is clean prior to installing the gasket and pump.
NOTE:
The heat shield may vary by model.
