Hi guys. My new 90 is making a serious knocking noise in the engine compartment and power is seriously down. My top speed is +- 100km/h. Ive taken the vehicle to my local dealer who has informed me that the reason for the above mentioned fault is a faulty ECU. the car has been there a week now and the dealer claims they are struggling to re program the new unit. Upon investigation I came across a TSB released not to long ago which perfectly outlines my vehicles fault. Does this TSB suggest a complete engine change or only a component? please see TSB below:
Title: 2.4 Puma Engine Knock Noise. Type: LD - Defender - All Years - Special Service Messages - Engine Name / Part No: SSM38792 Info Type: Service Bulletins Version No: 1 Date Uploaded: 21 Jul 2008 Models: LD - Defender 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. Reply With Quote Land Rover's don't leak oil, they simply mark their territory! |

Shorty,
Its a pity to know that other Defender Puma owner have this problem. It is a thread with a lot of information about this issue in this forum http://www.defender2.net/forum/topic472.html Regarding your question, as far as I unsderstand the engine assembly is almost all the motor!
