Engine System - General Information - Cylinder Bore Out-of-Round
General Procedures


1. NOTE: The main bearing caps or lower crankcase must be in
place and tightened to the specified torque; however, the bearing
shells should not be installed.
Measure the cylinder bore with an internal micrometer.
Carry out the measurements in different directions and at
different heights to determine if there is any out-of-
roundness or tapering.
If the measurement is out of the specified range, hone out
the cylinder block or install a new block.

Engine System - General Information - Leakage Test Using Smoke Test Equipment
General Procedures


CAUTION: The compressed air line supply pressure must be between 3.5 and 12 bar (50 and 175 psi) for the smoke test
equipment to function correctly. Do not exceed this pressure. Failure to follow this instruction may result in damage to the
smoke test equipment.
NOTES:


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


On vehicles with 3.0L TDV6, it will be necessary to insert smoke at both air cleaner outlet pipes independently if the right
hand turbocharger and associated hoses are to be tested.


In some cases it may be necessary to remove undertrays, trim or engine covers to obtain access to all potential leak
locations.


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


For further information regarding operation of the test equipment refer to the manufacturers operators manual supplied
with the kit.


1. WARNING: Use an additional support to prevent the hood
from falling if the smoke test equipment is secured to the
hood. Failure to follow this instruction may result in
personal injury.

Install the smoke test equipment to a suitable location
under the hood.














2. Connect a suitable compressed air line to the smoke test equipment.

3. Connect the smoke test equipment positive power cable to the battery
positive terminal.


4. WARNING: Do not connect the smoke test equipment negative
cable to the battery negative terminal.

Connect the smoke test equipment negative cable to a suitable body
ground point.

5. NOTE: A flashing green light indicates low battery voltage.
In this case, place the battery on charge and make sure
that the battery is fully charged before using the smoke
test equipment.

Observe the power indicator lamp on the smoke test
equipment. Make sure that a continuous green light is
displayed.

















6. NOTES:


In some cases it may be necessary to remove the air
cleaner(s) to allow access to the air cleaner outlet pipes.

In some cases it will be necessary to cap one of the
air cleaner outlet pipes. Use the blanking caps supplied in
the kit to cap the open orifice.

Disconnect the air cleaner outlet pipe(s).

7. NOTE: Make sure the smoke test equipment adapter is a
good fit to the air cleaner outlet pipe. This must be an air
tight seal.

Connect the smoke test equipment supply hose to the air
cleaner outlet pipe.
1. Install the appropriate adapter to the air cleaner
outlet pipe.
2. Connect the smoke test equipment supply hose to
the adapter link hose.




















8. NOTES:


The flow control valve must be in the fully open
position.


Smoke is produced for 5 minutes. The smoke test
equipment will automatically switch off after this period of
time.
Switch the smoke test equipment on.











9. Remove the oil filler cap, and observe until a constant flow of smoke is
visible leaving the oil filler orifice. Install the oil filler cap.


10. NOTE: The longer smoke is allowed to exit from a leak, the more
fluorescent dye will be deposited at a leak location.

Using the torch supplied in the kit set to white light, look for escaping
smoke. Alternatively, use the ultraviolet light to look for fluorescent dye
deposits at the source of a leak. www.JagDocs.com

Engine System - General Information - Piston Inspection
General Procedures Published: 11-May-2011


1. CAUTION: Do not use any aggressive cleaning fluid or a wire
brush to clean the piston.
Carry out a visual inspection.
Clean the piston skirt, pin bush, ring grooves and crown
and check for wear or cracks.
If there are signs of wear on the piston skirt, check
whether the connecting rod is twisted or bent.
