ormis Posted October 25, 2008 Share Posted October 25, 2008 I have posted this on another forum as well. Hope Im not breaking any rules. I have pasted the original entry below with my question below that In the Land Rover GTR appears te following service bulletin issued some weeks ago: Somebody with this trouble? Regards 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. Does anyone know the legal position here. I have just bought a new Defender less than 3 months ago and the symptoms re the engine knock all apply. Going by the quoted VIN number my car has the the unmodified engine. Can I reject the car and ask for a replacement or have a new engine fitted. Pity because I love the car. Advice appreciated Quote Link to comment Share on other sites More sharing options...
disco_al Posted October 25, 2008 Share Posted October 25, 2008 return to the dealer and get them to rectify the problem as a warranty claim Quote Link to comment Share on other sites More sharing options...
BogMonster Posted October 25, 2008 Share Posted October 25, 2008 It's already been covered on LR4x4 somewhere, not sure about your question though Quote Link to comment Share on other sites More sharing options...
