Hi folks
Many thanks for your input thus far.
These forums are so good for morale when you feel so despondent.
I hate doing things twice. The water leak means a strip down again and hanging upside down under the hood.
I suppose my main fear is the Allucill bore coatings on the M62 engine. I am told that they can fail very suddenly without giving a lot of notice. But don't know I am only going on what I am told by people that should know.
So gues I am going to have to bite the bullet and start the exploration.
If any one of you has any ideas of an order of progression it would be welcomed please.
Certainly any expensive don'ts.
Just incase it is not the worst case scenario.
Has anyone sorted the valleypan?
Am I better trusting to a good silicone bead? Or has anyone got a contact for a new gasket. [/i] Eddie the eagle watch out 👀

Have you compared your noises, to any posts on YouTube, with their own m62 engine noise. It's true that the vanos 'cogs' can be noisy, I did mine, and now silent. But you need to know what your noise is, and when it happens, and maybe things like different oil, ie, changed, ( thicker oil) and possible exhaust cracked, etc. Is the car now holding water, and driving ok. .

The noise from the engine is only occurring when engine is put under load as in accelerating. I cannot think of a way to replicate it when the car is stationary. I thought about a rolling road but that would need to be a all four wheel setup I would have thought. I don't know of one in our area. I have tried putting the Park break on and chocking the wheels but that isn't working. I have jacked a packed the cars wheels off the ground and started the car and put it in gear and applied breaks. This is not good practice choose however carefully you support the car. I would not recommend this, the RR suspension has a huge travel on it.
Can't hear anything with stethoscope other than the normal noises of the m62. I have listened to YT videos and recordings of VANOS and Timing Chain associated noises. But none seem to sound like this.
It is not tied into road speed or engine rpm. It is not apparent on startup or warm up or hot engine.
The oil has just been changed for the third time in twelve months of ownership and 10,000 miles of light road use.
No fault codes are being displayed or showing. The pink like knock and very occasional hesitation or miss was the reason I had the disg. done which showed a knock sensor loose on left hand back prior to me stripping the car down and rebuilding valley pan/ intake/ valve cover gaskets/ plugs and injectors.
The cars history was not known to me prior to buying the car the underside and shiny bits are good but over the twelve months many problems have started to show up that can only be put down to historical poor main dealer service in some cases and none LR trained people working on the car and bodging jobs or breaking thing because they didn't know how to get in to them correctly. Or even put them back on.
As I am not a wellhealed Range Rover owner that can afford to throw money at a problem at the main dealers. I was hoping before I had to jump in any deeper I could try to pick the forums brains and get the truly knowledgable people on hear to impart there analysis and advise as how to logically investigate and remedy this problem.
At the same time establishing a thread that may help others.
I am at the moment a RR Owner that loves the car and its whole ethos and I own one because I and my family like it and feel safe in it. Eddie the eagle watch out 👀

Pete...

Get the water leak sorted then bring it over, we'll stick the IID tool on it, live values, and check out the knock sensors, you can interrogate each one individually... hopefully sort it....

Not sure if mine will read live values on yours as is, it might need an additional licence for another vin...

(I'll pay for the additional licence if I can have that other old scrapper you have in the garage... ) Pete

Old scrapper?!!!
I presume you are talking about the misses 🙊
Good job she don't read the forum LOL.
May be quicker to put Old Dusty Bin back on the road at this rate Pete
On the other count that would be great and I am sure that the cost of the upgrade if nessarry is not insurmountable.
Do you know of any way of testing knock sensors as to get to them all the inlet/ injectors/ coolant cross pipes have to be removed before you can get the darn things out.
So to sort water leak on the valley pan put it all back without testing them would seem a bit daft if I can test them first.
I am not convinced that it is the knock sensors that's causing the problem as they looked in first class condition when I took them off last time. Eddie the eagle watch out 👀

I seemed to have stopped getting notifications of replies.
You may have already found this yourself but interesting information towards the end.
I now also have insomnia

Hi thanks for that link to the article. That was the one I had read about the collapsed cat syndrome. But I couldn't find it again anywhere. I was probably looking in the "JAG section!"
Sorry for slow response my son is home from school at the moment and it sort of puts most things on hold or at least in a state of utter chaos. School assignments take priority over car repairs I am afraid.
The collapse of the cat sounds to fit the symptoms nearly identical with mine.
Think the timing chain tentioner and guides are certainly something that will need to be done in the near future at 126,000 on the clock.
But I think I have to establish if the engine block is worth spending time and money on. Hopefully it will be.
I think I am going to first do a compression test on all potts and see what that throws up.
Then check the spark plugs for obvious signs of misfire or fuel starvation or rich sooty/ oily deposit.
Then if all is well whip the coil packs off one by one and see if the RPM alters.
If it still hangs on to its secrets I guess Shot of an injector problem the simple solutions have gone.
it's time to take the L sensors out and check the CAT.
If that is OK it's pay for a set of knock sensors and sort the water leak out. And screw th rad cap back on.
If that don't sort it then it's time to make the record and post to Utube.
See if I can take Pete out for a pie and a pint and have a trip across the bridge to Pete's again and have a play with his toys and see if his techno genius can show anything.
I can't thank you chaps enough for the support. My responses may seem flippant at times but that's my nature and it is a way of hiding utter dispare.
Any further comments are greatly received and let's me know that other people are either having a laugh at me or thinking the problem though with me. Which ever it's fine by me.

Definitely no need to apologise, i have been there with the assignments and the continual battle with the FF.
i wasn't getting email notifications although there were replies so think my email had blocked it as spam.

I am at 120K and i will probably be doing the timing chain guides and vanos at some point as you say, as long as the block is good which i believe it is. My water pump bearing letting go was my last major cause for my head in my hands as it sounded like cam chain guides.

i have been on the edge a few times and the biggest help i have had has often been just discussing the problem with a fellow sufferer, group therapy i thinks its called.

Diagnostics i would say is a massive help if you can stretch to buy one, i love the RSW allcomms but i think the GAP is popular as well now but the RSW Allcomms is dedicated entirely to the 2002-2005 FF.

The BMW forums are good as you have the BMW M62TU engine so that opens up a huge area of advice as there are probably millions of the engines worldwide and well documented on youtube.

These are very complicated but thankfully predictable vehicles and unless you own your own diamond mine, then main dealer or even indy repairs are simply not viable on most occasions.

keep the faith, the pleasure from owning the FF comes when you finally solve the mind bending puzzle as to what is wrong with the beggar, as well as driving it of course.
Good luck
