Carbon build - up its everyone’s problem.

[koshari]

He is correct about the intercooler.

Its upstream of where the egr carbon deposits are.

wow i think maybe start reading cause all diesal turbo start this nonsense

[craigleonie3499]

i have read all of these pages and i am starting to get worried. I bought my ml from a dealer (not mitsi) I have just done a 120k service no surging or rough engine as yet. I have noticed just of late that it is getting a bit rattly when starting up am I am concerned if this is the start. Has anyone put in a chip it egr blank if so how did it go. I am just concerned that by blanking the egr valve it will set of the engine light. Is there any way around this. I was also looking at putting on a catch can on the inlet manifold to try and feed fresh air. Snorkel ordered today is there any other recommendations to try and feed as much fresh air into the motor as I can without recirculating exhaust gases.
Thanks

I have a 3.2L Triton TD. I have had it to the dealer with a surging issue/running slightly rough when cold. After a ECU reflash and injector reflash at 82k still not fixed the issue. Sent it back and they have observed a carbon buildup. The triton is out of warranty by about 3 months so they are approaching mitsi to do it out of good will. I asked how much buildup there is but the useless service guy says they cant tell how much there is. Now that its close to chrissy there is no way it will be sorted before hand. So probing for info on whats inside my manifolds has weilded nada. I also asked if they clean out the intercooler as part of the carbon clean, and he reckons no as it is completely unrelated and there will always be a bit of oil in the intercooler from turbo shaft blah blah blah. Very annoying as I have no idea if I should be babying the car and not going on long trips etc. Is this guy correct? Ie cant tell carbon buildup extent and intercooler is unrelated?

If mitsi wont cover it, they are saying it will be at least 800 bucks for the cleanout. I have a diesel specialist quote 600 with intercooler clean and say, have you thought about blanking the EGR? So if no warranty ill go to the guy that sounds like he knows what he is talking about and is happy to give you some info.

Any thoughts?

There's actually a PDF around here somewhere with detailed DIY instructions. If you're half way handy and get the time over xmas you could save yourself some coin. I'd wait first to see what the dealer says though, just in case it's a yes.

Hi, I just got my manifold replaced (3rd time 85,000km), replaced gear box and new clutch. The outcome.... the performance is unchanged ...no power or acceleration, checked under the hood and found they only replaced the feeder tube and egr (they call it an inlet manifold) and left the actual inlet manifold untouched. Oh and the clutch is shuddering, at least the new gearbox lets me change gears again.....but now I cant take the boat down the coast... Mitsubishi's idea of a merry xmas! I'm with you, looking at cleaning intake manifold....blocking egr etc, or driving it off the nearest cliff, ha. Merry Xmas.

[jaybabybrowndog]

Yeah I was thinking over the holidays to clean it out myself, just a bit worried about fuel rails etc or where the pdf says "now this is where it gets tricky". Maybe ill just do the top to get an idea of the extent of the problem. But then again im thinking mitsi might do it and want to get the most for my potentially free money. But for peace of mind cant beat seeing with your own eyes.

[GraGRa]

An idea for you, ask the dealer to take a photo with an endoscope of the intake manifold, that's what they did on mine then they get ok from head office to do the job under warranty, but insist they do the whole manifold. One dealer I spoke to at Bega have exchange lower manifolds to make the process quicker, not all dealerships are on the ball or care..... avoid Narrabeen in Sydney....I heard yesterday the dealership is closing in a month, hope they fix my clutch before then.

[jaybabybrowndog]

Thats exactly what i was thinking they would do to check. So its weird to me they can ask head office to do the job but have no idea to what degree its all gummed up. Typical perth customer service, I just have to bite my tongue till I get what I need from them and then "advise" them of their substandard customer dealings.

Someone else had this shuddering problem recently.
Have a look here. viewtopic.php?t=15272
It might be an easy fix and you still might be able to get away.......albeit slowly.

So, the more I read, the more this is a PITA. I'm not super handy, but I'm not a moron either, as long as you don't ask my wife. Will mitsu cover warranty for the build up problems, or is it just a maintenance cost? If I blank the EGR, will I have to remove it before every service. It's my first brand new car with not 1000kms on it yet, don't want to void warranty or get burnt by anything this early on. Anyone northside of brissy that may be able to help?

[mattz]

With so few kms on it NOW is the time to blank the EGR.
Once you install the blank, see what you think about removing it before every service........Chances are they won't see it.
Many members have had their vehicles serviced with the blanks in and nothing was said. But if you want to be sure not to have any warranty problems remove it before hand.
Mits will cover any problems the carbon build up causes, under warranty but it can be a PITA.
Once the warranty runs out its your problem......save any hassles down the track and blank it now is my opinion.

[mattyk87]

Yeah that's what I was thinking, if it's not a PITA to do that's not a problem. If I cant do it, I'll let the warranty run it's course and deal with it then. I also don't want issues arising while I may be in the middle of no where. How much do these plates cost? Also should it make the car better or worse on fuel?

[mattz]

Send GLX-RAlex a pm.......he's the man.
They are pretty easy to install.

[DocBassett]

Matty, I am in the same boat as you. Not a mechanical genius. I attempted mine today. 3 of us tried to undo one of the bolts and all failed. So still no blank in.

[viking shippy]

Before you round off the nut doc get sone wd40 on it over night and try in the morning....

[mattyk87]

Maybe I have read too much in a short time, but I'm confused. Should I see better fuel efficiency? Seems some do, some don't. I have a glx auto mn if it makes a difference.

The difference is minimal, if anything the boost comes on a little earlier (think 400rpms), in an auto though I'm not sure how you would notice as I've never driven one back to back.

[DocBassett]

One step ahead of you VS

[GraGRa]

An update on my 3.2 triton, the dealer told me the intake/inlet manifold needed replacing for the second time, they did the job or so I thought. Anyway they only replaced the tube attached to the intake manifold and a new egr. My issue is and I will go them for it; that the dealership and Mitsu customer service, told me the intake manifold would be replaced and on the work sheet it states "intake manifold and a part number" replaced. Well they should google intake or inlet manifold and it's pretty clear and unambiguous as to what the part is..... so Mitsubishi has misled me by mislabelling a part and I believe I had a reasonable expectation to believe I would receive an inlet manifold. Further, if I was properly informed I could have been given the option of having the manifold removed and cleaned, now I have a half ass job done and still need the manifold cleaned, oh and the clutch they just put in replaced as well! What next, changing the radiator means replacing the hoses?

You're in brissy, Eagers at newstead should be your mitsy service centre

[sewerserpent]

Thanks heaps for your post.
I had the surging bit at about 100,000 K's,I took it into the local Mitsubishi dealer here in Tamworth and by the sound of things they did what you did.That fixed the problem.....for about 100,000 K's,it has reared it's ugly head again,just turned over 210,000 k's.
I think I'll have a go at fixing it myself,thanks to your efforts and pic's.
I do think Mitsubishi have a lot to answer for regarding this problem,seeing it happens to so many Tritons and Pajeros with turbo diesels.
Thanks again for your post.
Cheers,
Larry.

Suggest you have a --close-- read of this post then matty.

Hi Guys,
new to forum please excuse ignoranc but is this problem the old 3.2 diesel or is it still happening with the new 2.5 diesel as most posts seem to be 3.2. My triton is 2013 glx-r auto with 1400klm and only 5 weeks old.
So now would be the best time to blank off egr .

Thanks
humphrey

yep block that sucker off
