Thats weird. Simon should be along shortly to help. In the meantime, upload to google photos or picassa and share from there.

Ok...so you are cleaning intake manifold. Will you also be servicing the throttle body and all other things ontop? I ordered the 3 x O-ring seals yesterday for the throttlebody...decided to start there and work down. The o-rings on the throttlebody is almost R60 each.....
Since you took everything appart now....would you recommend I tackle the whole intake system as a whole or is it ok to do throttlebody now and the rest later?

The problem with linking to offsite images is that IMHO it makes this form more fragile - look at how many links here (and on the aussie forum) point to images that are no longer there.
Anyway - I will do that (link to external images) for now until Simon helps me overcome my problem (I have even further shrunk my images - to about 300kB and still get the same error message).
OK so here are a few images that I posted to my flickr site:
(I will comment at the bottom of this post on some aspects of my findings)
1. Inlet manifold throttle body port - throttle body removed.
2. Ports 2 & 3 on the inlet manifold.
3. EGR inlet port - EGR removed.
4. Throttle body.
5. EGR body.
6. Inlet into throttle body from intercooler.
7. Head inlet ports.
8 & 9. Gas filter assembly and boost air temperature sensor.
BTW all the images I took are here: Pajero 3.2 Di-D pre-common rail inlet system
So here are my comments / questions.
It looks to me like the EGR system itself is not a dirty as I first thought - mostly a fairly fine layer of dry soot.
However, the feed from the intercooler does not look good at all - a wet oily build up on the throttle body butterfly, body and in the feed pipe from the intercooler. From the manifold and head ports it looks like most of that gets sucked into cylinders #1 and #2.
Presumably the only place that that could come from is the turbo - leaves a bit of a sinking feeling. Anyone with more experience care to comment (bearing in mind 240 000km)?
The engine does not smoke since Alan Black fitted refurbished injectors about 10 000km ago. But I did notice that my oil consumption may be up (needs top up between 7500km services).
Also looks like I may be losing a bit of oil at one of the injector pipe-head seals.
While I am cleaning all this up, what else should I replace / service?

Thanks for the feedback.
While I have it in a million pieces it makes sense to replace the throttle body O-rings I guess. Not sure what else should be done.
In reality, in my case at least, and with the benefit of 20/20 hindsight, and seeing that there is not as much build up as I first suspected, I don't think I will get much more benefit from having done a complete strip down. However, I have seen images of other inlet manifolds looking way worse.
You should be able to gauge this once you have removed the throttle body.
So it seems like I can't upload attachments AND neither can I insert / link to web images.andrew.ashton wrote:OK so here are a few images that I posted to my flickr site:
Hopefully, as Marius says, Simon will happen along and tell me in what way I am being dof and then I will fix the post.
From what I could gather, it's only three o-rings that is not reusable once the throttle body has been taken apart. 2 of those have the same part number.andrew.ashton wrote:While I have it in a million pieces it makes sense to replace the throttle body O-rings I guess.

Reason I'm replacing the o-ring is because there is some oil around the throttle body and I have no idea where it comes from. Like you said...I will probably know where the oil comes from once opened up.andrew.ashton wrote:You should be able to gauge this once you have removed the throttle body.
Thinking of taking the pajero for an engine wash to see where new oil leaks appear...but I'm a bit skeptic about engine washes.
I'm not experienced or clued up with vehicles at all, this is all a learning curve for me...luckily I have access to this forum. Knowledgeable and friendly people with excellent advise.
Please keep us updated on your progress, I'm collecting parts this week and hopefully will tackle the build next weekend. Should I keep it in this thread or start a new thread for the throttle body?
Looking at the pic I took...I'm not so sure it's the throttle body leaking all the oil...but rather the vacuum system????? Does this work with hydrolics?
The arrows indicate the gaskets I've ordered and think that is the only ones that needs to be replaced.
I don't want to hijack your thread...so please feel free to tell if I should start a new thread.....I'm just thinking that this is something you'll be doing as well.

I would say you should look at the state of the inside of the pipe from the intercooler - you will quickly judge if that is the source of the oil - seems likely.MThompson wrote: Reason I'm replacing the o-ring is because there is some oil around the throttle body and I have no idea where it comes from.

I presume the throttle body O-rings are not to stop oil leaking out, but to stop air leaking out.
What km is your paj on?
Amen to that!MThompson wrote: I'm not experienced or clued up with vehicles at all, this is all a learning curve for me...luckily I have access to this forum. Knowledgeable and friendly people with excellent advise.
Yup - will keep you updated.MThompson wrote: Please keep us updated on your progress, I'm collecting parts this week and hopefully will tackle the build next weekend. Should I keep it in this thread or start a new thread for the throttle body?
I suggest that you start a new thread for your throttle body refurb - maybe with a link in this thread and use a subject like: "3.2 Di-D Throttle body service"
