Title: 2.4 Puma Engine Knock Noise.
Last Modified: 21-JUL-2008 09:44
Category: Engine
Symptom: 497000 Engine Noise

Content Issue: Heavy audible knocking heard on start up.
Cause: On start up oil pressures can cause the piston cooling jets, (PCJ), to latch into a zero flow condition. Due to hysteresis effect in design the jets do not unlatch until the engine is warm and the oil pressures lower again. During this time with no pressurized oil jet flow to the lower pistons / cylinder bores, overheat and scuff conditions / damage can occur.

Action: Replace the engine assy but ensure only engines post serial # ELD00080707063602 are used.
This condition will not occur on vehicles post assured Vin# 9A767162.
Engines post the info above are fitted with modified PCJ internal springs and this issue is now closed.

Title Mulitiple Starter Motor Failure
Last Modified 21-JAN-2009 17:43
Category Electrical
Symptom 203000 Basic Electrical
Content
Issue:
Repeat failures on Defender starter motors.
Cause:
The ignition switch can jam causing starter motor failure due to over running.
Action:
If the starter motor has failed check operation of ignition switch;
a) Is the switch jammed through any of its positions?
b) Does the switch fully return to position 2 once cranked and the inhibit operates, not allowing re-crank from position 2?
c) Does the starter motor continue to engage once cranked and key released?
If the answer to any of the above is YES please change ignition barrel as well as starter motor as potentially the starter motor will fail again.
Vehicles post vin. 775971 have been modified and should not demonstate this concern.
