I took the head warranty mechanic out in mine for that issue and he advised it was just the injectors opening and closing. Sounds very much like old school pinking. I ran some injector cleaner now add 2 stroke to the diesel and its not as pronounced.

Thanks Roy.
Am i right to assume that when the mechanic says it is the injectors he means there is a problem with the injectors? if it was just a normal noise from the injectors all vehicle would have the same issue but that is not the case I will try an injector cleaner as well, run a couple of fuel tanks and see how it goes. I wonder if engine oli could have a part to play in it as well. |

He didn't say it was a problem. He said the injectors learn how you drive and some driving styles exaggerate the noise. He also said its not mines not the worse one he's heard and it's nothing to worry about... We shall see. He seemed like a genuine bloke so took his words for what they were.

Have you checked engine and gearbox mounts & security?

I haven't check those but the gear box was pulled down not long ago when I had the clutch replaced ( mechanical failure )so I assume that would not be the problem, it is definitely not just a vibration and I am convinced it is not a "normal " sound the injector should do. And those injector definitely have not learned how I drive or they would not do this to me
I am having another mechanic looking at it in a couple of days and I will post what he says. |

OK so I went to another mechanic who said.... it definitely sounds like pre detonation noise of petrol engine. possibly due to ECU early firing problem ?!?. to a certain degree it is to be expected in diesel engine but not this much
Still puzzled, and now I even have the engine light on. Still love the Defender but I certainly did not expect so many issues from such a "royal brand" : water leaking in when it rains.... clutch failed at 100.000, aircon working only in 20 min blocks, very poor cabin seal ( dust everywhere) , transfer case oil leak at 70.000k just to name a few |

latest development. I bought a bottle of additive/fuel doctor ( I felt better than using 2SO). Added 50ml to the full tank. went through the whole tank and surprise surprise..... rattle is exactly the same as before yesterday engine light came on again today went to the land rover mechanic the supercomputer diagnosed a fault in the injector ( really??) tomorrow I will try add to the fuel half litre of Extra virgin italian olive oil, 50 ml of Balsamic vinegar and 15 mi of holy water.
ps. LR mechanic said this is 100% not a normal rattle. it is pre detonation but not of acceptable level. |

Mate,
not sure if its the same thing but my last 2.2 90 puma had what can only be described as "pinking" had it back to the dealers head Honco went out and said its normal, so I just got used to it I now have a 14 plate 110 station wagon and that is not as pronounced but you can hear it faintly now and again. if I remember it was more noticeable in certain gear / speed combination's on the 90 Current Landy is a 110 2.2 Puma bit different from my first one a Series 1 with a straight 6 petrol engine last one was a 2.2 puma 90 but the M4 crash barrier took care of that !!!! |
