replacement inlet manifold

[trouble]

Mine is the same as yours is Subi.
Thanx for the info and photo welldone a wealth of knowledge.

Just checked and mine is in the original sh1thouse spot
so it looks like I might be in for some carbon fun...

[rick]

book it in lad and get it done

[smeghead]

My stealer told me that mine would not need replacing as it was a late enough model...

And that was just last week!!

[rick]

bull shit that,mine had a hotfix number for all the work

[smeghead]

I went in and reeled off the symptoms (which I don't have yet). He claimed it was a stickin suction control valve that was problem... Do you have the hotline number handy? Might be some good ammo...

That being said, the car is going great after getting the suction control valve replaced...

[brenze87]

what are the symptoms that you guys have been telling the dealers to get the work done.

Had the inlet manifold replaced yesterday, don't know if they replaced the MAP sensor or just re-located it on the new section of manifold, because the ute is still hunting for the correct fuel mixture some of the time (accelerating 2-3k in 3rd for instance). Or perhaps the MAF sensor is more likely...
I suppose driving the ute after they did the modification would have been too much to ask. Much easier just to drive it through their car park and tell me it's fixed.

[rick]

have you had your suction control valve done yet? that cured my hunting problem

[Jitsukablue]

That's next on the menu Rick, It's going in next week... again...

I read these posts about the carbon issues and decided to check my 06 triton. It had been running well with 60000 on the clock but I decided to check the inside of the manifold anyway. Yep- full of carbon. So I cleaned out the intake pipe to the manifold and got about 1 1/2 coffe cups of carbon out and noticed that the inlet of the riser pipe to the manifold was becoming restricted. I spoke to a forman mechanic at a stealers and he said that the manifold would not be replaced unless it choked up and created an engine problem and that the new remaping software goes some way toward reducing carbon build up.

But here are a few things to think about.
1) The carbon is comming from the exhaust that is directed back into the intake - why?- emission control I presume
2) The new intake shifts the turbo boost control vacuume line to in front of where the exhaust comes in, therefore preventing it from blocking with carbon. But is carbon still going to eventually build up and choke off the intake?
3) If you want no carbon then don't pipe exhaust back into the intake. The stealer mechanic told me the engine would simply not run if the pipe from the exhaust to the intake were blocked off. WRONG it does run and runs fine. But I am scared to leave it like that incase there is something I am missing and this exhaust is needed.
4) Less carbon in the exhaust must equate to either less fuel being delivered, hence less power. Therefore the remapping would mean a less powerfull engine. Or the little servo motor that regulates the amount of exhaust delivered to the intake is reprogrammed to allow less exhaust back. Whick is kind of like blockinig it off.

Anyway let me know if any of you know more about this than I can reason as I am keen to find out more about the problem. By the way the small turbo boost control vacuume line was blocked on my car and it was still running. Any suggestions

welcome mlee - these EGR threads might help you out

closing the EGR valve
i blocked off my EGR today

Had a 45K service and asked for the Inlet manifold problem be looked at as I was losing some power. At this service they agreed to replacement the manifold and stated they needed to order in the parts and it will take 3 weeks. After 5 weeks I contacted them and there reply was 'On checking with the parts there are no parts on order. The reason for this is the inlet manifold we have been fitting to some Tritons as a modification is not compatible to your vehicle as is it a Thailand specification'

Does anyone know that some models will NOT get the Mod?

They never contacted me about not ordering in the part or offering any alternative solution. No contract at all.

They did offer in there reply that if the problem occurs again, contact them for further investigation. Like to have it fixed before warranty expires early next year but look as if the problem will remain with my model of the Triton.

[Buzzy]

Is yours the 3.2 Wood?
Shouldnt be any diff to ours.
Tell em their dreaming

[WoodGnome]

Yes Bussy

Its a 3.2 Auto. XLS version.

That what I thought to, but I'm not the expert.

Is the Triton assembled in more then 1 country?

[Buzzy]

Yes.
Its assembled in Thailand & South Africa I think.
Not sure if its assembled anywhere else though

[WoodGnome]

I have been told that the Thailand version does not have the carbon buildup problem. They state "the type of inlet manifold on your vehicle are not having the carbon build up problem. Therefore it does not need to be replaced."

I also asked where the triton are assembled and there answer is:
"I think there are only made in Thailand and Japan. The only vehicles we had problems with has been the ones made in Japan"

I would like to know from the forum members that has had the new manifold installed if there Triton is a Japan or Thailand version. Or is there an engine version number stamp on the cars to check which will have a problem and those that will not?

[Buzzy]

WoodGnome,
I believe the ML's when first introduced were made only in Thailand. 06 / 07 models.
These models (which mine falls into 07) have the old style inlet manifold.
Only recently have they started assembling them in SA.

I would think that all models irrelevent of where they are assemble now come with the updated inlet manifold.

Does that make sence

Not sure if I am too late to get answers/advice from ya's but I am going to dealer tomorrow because of an unrelated engine check light so I thought I would take this opportunity to hassle about my inlet manifold can anyone advise that my arguable symptons are:

1. poor fuel economy
2. loss of power
3. gradually getting worse

Any additional symptons to add ?

I have read this thread but it does not specify exactly what people are saying to convince dealer with symptons.

I have an 08/08 build and from Subi's photo's I have the old inlet manifold.

Also, I know this is on the other side of the engine but should I be pulling my egr blanking plate out for tomorrow or even when/if it gets done or will they never know ???

[daryn]

At dealers now and have been told that the engine check light must come on before they replace inlet manifold, is this crap or what. Supposedly it can detect carbon build up, pretty smart these Tritons.

Do they have to wait for the engine check light to come on before they can go to the toilet.

[Naff]

As soon as I ASKED them to check my manifold and THEY FOUND carbon buildup they were going to replace it. If you had carbon buildup Daryn, it's not normal and should be fixed under warranty. Don't take that shit.

Reminds me - I have to book it in to get done.

[daryn]

They have reset the ECU so that it will relearn my driving style this will supposedly fix my fuel economy.

[Buzzy]

Daryn
My local just ordered the inlet manifold for me beacause I asked.
Still havent got it fitted yet though, must get around to that.

They know there has been problems so just ordered a new one straight away

[daryn]

Thanks Buzzy, I will be back soon to get the power steering switch done so will hassle them again then.

I had my Triton at the stealers today getting some problems fixed , whilst I was there I commented on the carbon build up and was told that "there is a new intake cleaner they have just got hold off and which will clean the carbon out of the intake manifold, it is similar to the Subaru but haven't worked out a price yet." They heard it does a "pretty good job", and also "some people are putting in a egr blanking plate" to stop this from happening.
