Inspection and Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.
Visual Inspection
Mechanical Electrical Coolant leaks
Oil leaks
Leaks in the fuel system
Visibly damaged or worn parts
Loose or missing fixings Fuses
Loose or corroded electrical connectors
Harnesses
Sensors
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.

4. If the concern is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the relevant DTC Index.
Symptom Chart

NOTES:


If an engine is suspect, and the vehicle remains under the Manufacturers warranty refer to the Warranty Policy and
Procedure manual (section B1.2), or determine if any prior approval programme is in operation, prior to the installation of a
new engine.


Due to the possibility of loose carbon, that has become trapped between the valve face and seat, effecting the pressure
readings, when carrying out a compression test and some cylinders are found to have low pressures, install the spark plugs,
road test the vehicle and re-test the suspect cylinders. If the correct pressures are restored, no further action is required. www.JagDocs.com

For a list of DTCs that could log in the Engine Control Module (ECM) refer to section 303-14. REFER to:

Electronic Engine Controls (303-14C Electronic Engine Controls - V8 5.0L Petrol, Diagnosis and Testing), Electronic Engine Controls (303-14D Electronic Engine Controls - V8 S/C 5.0L Petrol, Diagnosis and Testing).

9. WEAK VALVE SPRINGS: When the needle oscillation becomes more violent as engine RPM is increased, weak valve
springs are indicated. The reading at idle could be relatively steady.
10. LATE VALVE TIMING: A steady but low reading could be caused by late valve timing.

11.
IGNITION TIMING RETARDED: Retarded ignition timing will produce a steady but somewhat low reading.
12.
INSUFFICIENT SPARK PLUG GAP: When spark plugs are gapped too close, a regular, small pulsation of the needle can
occur.
13. INTAKE LEAK: A low, steady reading can be caused by an intake manifold or throttle body gasket leak.

14.
BLOWN HEAD GASKET: A regular drop of fair magnitude can be caused by a blown head gasket or warped cylinder head
to cylinder block surface.
15.
RESTRICTED EXHAUST SYSTEM: When the engine is first started and is idled, the reading may be normal, but as the
engine RPM is increased, the back pressure caused by a clogged muffler, kinked tail pipe or other concerns will cause
the needle to slowly drop to 0 kPa (0 in-Hg). The needle then may slowly rise. Excessive exhaust clogging will cause
the needle to drop to a low point even if the engine is only idling.

When vacuum leaks are indicated, search out and correct the cause. Excess air leaking into the system will upset the fuel
mixture and cause concerns such as rough idle, missing on acceleration or burned valves. If the leak exists in an accessory
such as the power brake booster, the unit will not function correctly. Always repair vacuum leaks.

Engine Oil Pressure Check


NOTE: Prior to checking the engine oil pressure, a road test of 6 miles (10 kilometres), must be carried out. Do not
attempt to attain engine normal operating temperature by allowing the engine to idle.

1. Disconnect the battery ground cable. Refer to section 414-00 - Charging System - General Information of the workshop
manual
2. WARNINGS:
The spilling of hot engine oil is unavoidable during this procedure, care must be taken to prevent scalding.
Wear protective gloves.

Remove the engine oil filter element
REFER to: Oil Filter Element (303-01C Engine - V8 5.0L Petrol, Removal and Installation).
NOTE: Ensure the oil filter element is not contaminated during this procedure
3. Install the oil filter element into special tool (Oil filter adapter number 303-1451)

4. Install the special tool (Oil filter adapter number 303-1451) to the engine. Torque: 25 Nm

5. Install the special tool (Oil pressure testing gauge, 303-871) and tighten the union
6. Connect the battery ground cable

7. Refer to owner hand book, check and top-up the engine oil if required

8. Start and run the engine
9. Note the oil pressure readings with the engine running at idle and 3500 RPM

10.
Turn off the engine

11.
Disconnect the battery ground cable
12. Remove the special tools
1. Clean the components

General Procedures

Check

CAUTION: Before disconnecting or removing components, make sure the area around the joint faces and connections are
clean. Plug open connections to prevent contamination.
NOTES:


Removal steps in this procedure may contain installation details.


Some variation in the illustrations may occur, but the essential information is always correct.


The vehicle battery must be in good condition and fully charged before carrying out this procedure.

1. Refer to: Ignition Coil-On-Plug - V8 S/C 5.0L Petrol (303-07B Engine Ignition - V8 5.0L Petrol/V8 S/C 5.0L Petrol, Removal and Installation).


2. CAUTION: Make sure the fuel injection system is
disabled before carrying out a cylinder compression test.
Failure to follow this step may result in damage to the
vehicle.
Repeat procedure for the other side.















3. Crank engine for approximately five seconds to remove any remaining
fuel in the cylinders. www.JagDocs.com

Operating Temperature Range -40 to 160 °C (-40 to 320 °F) Oil Level Check

For additional information, refer to Engine Oil Draining and Filling (303-01A, General Procedures).

For accuracy, oil level checks should be performed with the vehicle on level ground when the oil is hot. The vehicle needs to
stand for approximately 10 minutes, after the engine is switched off, to allow the oil to drain back into the sump pan and the
oil level to stabilize. The oil level system will not give a reading until the oil level has stabilized.

With the ignition on, the engine stopped and the transmission in P (park), repeatedly press the trip button on the end of the
LH multifunction switch until the oil level icon and applicable message are displayed in the fuel gage/trip computer area of the message center, as shown below:



Item Description A Oil level is between 50% and 100% of recommended level. No top-up required. B Oil level is between 12.5% and 50% percent of recommended level. Add 0.5 liter (0.53 US quart) of oil. C Oil level is between 0% and 12.5% of recommended level. Add 1 liter (1.06 US quarts) of oil. D Oil level is above maximum for safe operation. Reduce oil level to recommended level. E Oil level is below minimum for safe operation. Add 1.5 liters (1.59 US quarts) of oil, then recheck level. F Oil level is stabilizing. Wait 10 minutes and then recheck level. If this display is accompanied by the message ENGINE OIL LEVEL MONITOR SYSTEM FAULT, a fault with the oil level monitoring system is indicated. System Fault Warning

If there is a fault with the system, in addition to being displayed during an oil level check, the message ENGINE OIL LEVEL
MONITOR SYSTEM FAULT will be temporarily displayed when the ignition is first switched on.
