V6 Inlet manifold rattle

I have a Freelander 2.5V6 2001 and the inlet manifold butterflies are rattling.
The new part is really expensive plus a lot of labour so I need to find a cheap way to fix it.

I also heard the cause is the ECU software so if I just replace it the problem will come back.

Does anyone know this concern?

Are there any independant specialists in Wiltshire area that can maybe repair or modify the manifold??

Thanx

i have same problem and know a cheaper cure. email me on [email protected] for more info.............phil............

Hi Phil,

I received my Rover 75 inlet manifold from the breakers today and fitted it up with new gaskets. The whole job cost £150.
I already had the A151 download and have again confirmed it as OK.
Fingers crossed this does not come back.

Thanks again for your help - you are a star.

no problems mate glad to help--anybody else need help if i can help i will just call / e-mail and i will return asap ---- phil-------------

I have exactly the same problem (2001 V6 ES Auto with the hideously rattly inlet manifold) and having previously browsed this forum have been emailing Phil004.


I have just spoken to him on the phone and he has told me how to get this fixed for a fraction of the cost Land Rover are quoting - robbing buggers !

Rover 75, partsgateway etc

Phil, you should post all this info in this forum... I am sure there are lots of other people out there with the same rattle and I easily found this forum by searching Google for the problem.

Thank you very much Phil - and to your lass for finding that website!

Well, I've got it fixed...

Landrover were quoting £400 + VAT + fitting. I got it done for £200

£150 for the inlet manifold from a Rover 75 engine from a breaker's yard and £50 to have a local garage fit it.

I still haven't had the A151 software upgrade yet because I am fighting with my local Land Rover dealer over this.

However the car is brilliant... not rattly, quiet, sounds like a V6 again.

I have got to say that my rattle came on so gradually that I did not realise how much it had affected the car's performance. The only thing I did think was that the (auto) gear change seemed more lumpy, slower, not as sweet.

Now that I have had this done I am amazed how much better the engine is: not just quieter, but smoother, faster and more responsive and the gear change is back to how it used to be, smooth, quick and almost unnoticible.

If anyone is wondering whether it is worth getting this job done... it is definitely worth it - it's like getting a new car. I am amazed how much difference this stupid inlet manifold makes!

I bought the car about 18 months ago, used, from a Land Rover main dealer. They sold the car from new, took it back in part-ex and then I bought it from them and was the second owner. This software fault was known to them (but not me!) at the time and yet they didn't do the update which would have presumably cost them nothing but a half hour attached to a machine.

Just before my first service about 10 months later it had started developing the rattle. They told me what it was and that I would either have to live with it or pay them the £400 + VAT + fitting to have a new manifold. They still didn't bother to tell me that it was a Land Rover software fault and that there was a software update that would stop it getting worse.

What a bloody good ruse... they know that there is a problem with the software that controls these engines... but don't do anything about it. So, later, the hapless owner takes it back and pays £100's to have them put it right. IT WAS CAUSED BY THEM and they didn't bother to do anything to put it right.

I used to sell cars but, by God, I hate these robbing buggers!

Anyone else had a similar experience of being ripped off like this?

Mike

I got mine fixed too, thanks to Phil for a cheap solution!!

I don't know if you have got the manifold fault solved yet but i repaired mine three weeks ago cost £140 the lot and if you ring LR with the vin no and ask them to tell you what recalls the car has had they should tell you it will be on they central database. i got my inlet manfold of partsgateway and fitted it in 1hr and LR where very good mine had 4 recalls A151, auto box solinoid and download and two others ? LR stratstones in Glos where very good booked it in for two day and done them all FOC even asked if i want a loan car i got the info of phil owe him a pint
any info email me

There is a growing body of opinion on other forums for cars that use the KV6 realted to the inlet plenum issues.

1. Too much oil is sucked into the plenum from the breather system. This contaminates everything and it is thought can lead to tight VIS valves resulting in dead actuator motors due to stripped gears. The fix for this, is a good wash out with meths and fitting an oil catch tank in the breather circui to condense out the oil vapour before it reaces the plenum.

2. Failure of the VIS actuator in some posiiton or another resulting in more load on the valves over a longer period. Inside the VIS motor there is a printed circuit board containing 2 switches, a relay, diode and various terminals. The soldered joints for the switches can fail resulting in intermittent operation. This is made worse by oil contamination. This can be fixed by bolting the switches to the PCB and resoldering.

If anyone has a dead plenum, I am after one to find out if it can be repaired

There is a lot of activity on varous MG forums related to the KV6 inlet plenum woes.

It looks like the actuators are the first things to go. These are easily replaced and if you are handy with a soldering iron can often be repaired. Inside the actuator there is a printed circuit board with limit switches soldered to it. The soldered joints fail, leading to intermittent contact. This is not helped by the ever present oil mist. The joints are easily resoldered and to "belt and braces" this, the plastic locating pegs on the switch can be drilled out to 2mm and 2mm or 8BA nuts and bolts fitted or drilled and tapped to accept 8BA or 2mm threads.
Make sure that screw heads do not short out any of the PCB tracks and if you use nuts and bolts, locations in the plastic case may need adjusting. Better than spending £500+ on a new plenum.

I had the same rattle, followed Phil004 advice and it all worked perfectly, cheers Phil.

Hi Phil,
I have sent an email to you from my work yesterday if you do not want to reply to this email address you can use my email [email protected]

freelander has now come to a stop so i will be removing manifold this weekend

Cheers mark

this has been covered many times before - yes the Rover 75 uses the same system and replacing the manifold with that from a R75 certainly fixes the fault (until the next time). There are pictures somewhere of an oil catch tank fitted. I have two vis valve motors left over from my KV6 fiasco if anyone needs them.

Id just like to clarify something. The part you need is the Inlet Manifold Chamber not the Inlet Manifold. I just spent £90 on an Inlet Manifold to find out it isn't the right part. The Inlet Manifold Chamber sits on top of the Inlet Manifold and this is where the rattle comes from inside.

woohoo
yes i too have an expensive rattleon my freelander kv6 , them poor folk at landrover obviously need my cash more than i do, but they aint avin it.so can anyone tell me pls do i need the inlet manifold or jus the manifold chamber ? and is this a job for a competent diy`er any help and advice would be great. cheers dibbs

Chances are it aint ya fannymold, but ya Vis valves or motors. The motors are quite cheap, but it depends whether ya flappy bits are broke n awl. if yu wanna replace the complete inlet fannymolds then gerrem orf a Rover 75 - they are the same, but cheaper. Download a Rave manewel and read up about it - its one of them Hippoo design features.

if im understanding this right machan said tis were me flappy bits broken said it woz rattling when he shook it so i gues it needs that not sure wot a vis valve is or the motor (sorry) is it an easy job? thanks for the help

yup - yer flappy bits are ya Vis valves (variable intake system) thems be bits of placky which are actuated by ya Vis motors (cheap nasty lumps o ****e) which are easily clogged up with the oily goo wot leaks into yo intake, hence the bit above about fitting an oil catcher. Yo Throttle body also gets gummed up anawl - so its a good mod, if yu like spending munney - but yu must like doin tha, coz yu bought a Hippoo, and a KV6 Hippoo anawl.

hope tha helps, fur now.

take it ya dont like freelanders and im starting to see why,its my first 1 and my wallets already lots 3 stone thanks for advice

lets just say I had a bad experience once.
