1 Inlet camshafts 2 Exhaust camshaft 3 Inverted tooth timing chain 4 Nylon chain guide 5 Auxiliary chain tensioner 6 Auxiliary drive chain 7 Oil pump drive 8 Auxiliary drive camshaft 9 Timing chain tensioner 10 Tensioner lever 11 VCT unit 12 VCT solenoids The lightweight valve train provides good economy and noise levels and is chain driven from the crankshaft.

Double overhead camshafts on each cylinder head operate the valves. For each cylinder head, an inverted tooth timing chain
transfers drive from the crankshaft to the VCT (variable camshaft timing) unit on the front of each camshaft. Graded tappets
enable setting of inlet and exhaust valve clearances.

Each timing chain has a hydraulic tensioner operated by engine oil pressure. The chain tensioners incorporate a ratchet
mechanism, which maintains tension while the engine is stopped to eliminate start-up noise. The chains are lubricated with
engine oil from jets located at the front of the engine block. Nylon chain guides control chain motion on the drive side. VALVE TRAIN

The input shaft of the oil pump is driven from the front of the
crankshaft, by the auxiliary chain, at 0.87 engine speed.

The oil pump draws oil from the sump pan through a centrally mounted pick-up pipe. The oil is pressurized and pumped
through an output tube to the cylinder block. After passing through an anti-drain valve and a plate type oil cooler, the oil is
filtered by a replaceable cartridge installed on the front of the RH cylinder head. LUBRICATION SYSTEM

cooling jets and the timing chain lubrication jets.

The oil returns to the oil pan under gravity. Large drain holes through the cylinder heads and cylinder block ensure the rapid
return of the oil to the sump pan. System replenishment is through the oil filler cap on the LH cylinder head cover.
An oil evacuation tube is installed to allow oil to be drawn from the sump pan. The upper end of the oil evacuation tube is
located under the oil filler cap.
An oil drain plug is installed in the RH side of the sump pan.

Oil level monitoring is provided by an oil level and temperature sensor that measures the oil level in the sump pan. The oil
level can be displayed in the message center of the instrument cluster.



The oil level and temperature sensor supplies the ECM with a signal containing the level and temperature of the oil in the sump pan. The oil level and temperature sensor is secured to the bottom of the sump pan with three screws and sealed with a
gasket.

The oil level and temperature sensor sends an ultrasonic pulse vertically upward and measures the time taken for the pulse to
be reflected back from the top surface of the oil. This time is compared with the time taken for an ultrasonic pulse to travel a
reference distance within the oil level and temperature sensor to determine the oil level. The oil level reading is combined with
the oil temperature reading and transmitted in a PWM signal to the ECM.

5. CAUTIONS:


Make sure that the area around the component is
clean and free of foreign material.


Inspect the 3 timing chain oil nozzles for signs of
damage, install as necessary.

















6. NOTE: Using a suitable tie strap, position the
tensioner to one side.

General Procedures
Check Published: 10-Jul-2013

1. Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).


2. WARNING: Do not work on or under a vehicle supported only by a jack.
Always support the vehicle on safety stands.
Raise and support the vehicle.

3. Refer to: Valve Cover LH (303-01D Engine - V8 S/C 5.0L Petrol, Removal and Installation).

4. Refer to: Valve Cover RH (303-01D Engine - V8 S/C 5.0L Petrol, Removal and Installation).

5. CAUTIONS:


Rotate the engine clockwise until the camshafts are positioned as
shown.


Do not rotate the crankshaft counterclockwise. The timing chains
may bind causing engine damage.


Camshaft lobes must be 180 degrees away from each valve tappet
or valve clearance will be incorrect.


NOTE: Using feeler gauge check the gap between the tappet and
the camshaft lobe and check against specifications table.

Using feeler gauge check the gap between the tappet and the
camshaft lobe and check against specifications table.
Repeat for the remaining valve tappets.
