Hi,
First time post - Just want to say a big thank you to NTN and Tony (tony@spvindustries.com). I have always wanted a 4WD and bought a new 2013 MN 2.5L Man GLX which has been fantastic. Only recently I discovered NTN and have read all 48 pages on carbon build up plus a few other threads. I have 28000k on My Triton and on advice from Mitsi I've paid for about 3-4 x engine decarb in 3 years - I thought this excessive. They said I was a "soft" driver (not a lead foot) - which could lead to excessive carbon build up - although I don't have any carbon build up symptoms as yet - this led me to be proactive . and so I found NTN and did lots of reading and have recently purchased Tony's EGR controller - money well spent and installed yesterday - so easy. I also happened on a thread and purchased a windbooster from Boycee http://www.4wdsupplies.com.au. Needless to say the Triton has been transformed with these 2 mods and without the wealth of knowledge from forum members and Moderators this would not have happened. Thank you. Cheers Dazza :D .

If you only do one mod to your ML / MN it would have to be Tony's SPV mod...
Reading through this site is the best investment in time you could make, when the dealer starts trying to pull the wool over your eyes because he either wants some more of your hard earned money or doesnt actually know the answer, you will probably find it on here .
You get what you pay for... thats if your lucky!!

I should think it would vary from dealer to dealer whether they fully clean out the intake when they do an overheat warranty engine repair/replace. In my case the work was done at 112,000k and the dealer did absolutely nothing else. My guess is that the manufacturer will not pay for any other work, so the dealers don't do it. So unless you are aware of it, request it be done AND pay for it it will not get done.
At about 140,000 k my ute started the usual - surging - losing power - blowing volumes of black smoke etc. I fitted the original Tony mod and a catch can, after doing a couple of initial adjustment to the mod fitting (they had a tiny little screw adjuster which had to be backed off 10 turns) the motor has never exhibited those symptoms or problems again. It is possible the whole EGR system is still clogged with carbon and tar, but as long as the EGR valve will still shut and seal the motor will always run perfectly.
Unfortunately my engine still overheats, I have been everywhere and there is no obvious problem, as I previously posted the latest dealer advice is that bug damage closing the oil and intercooler fins may be the problem, and (not in writing) the genuine Mitsui alloy bull bar may have some effect in reducing radiator airflow. I think we all know there is a deeper problem within the 2.5 DiD engine causing these overheats but obviously Mitsi feel they have done enough now the car has 181,000 k.

G'day all, is there an easy way to check for carbon build up in the intake without having to pull the manifold off?

Does "Tony's" electronic EGR mod work for the MQ Triton?
Most of the talk here is from owners of ML and MN Tritons. Should I get the catch can for my MQ pvc system as well? Thank Russ

I just found the answer on Chiptuning's website. It seems it is not available yet as a plug in. Bugger lol

Do manifold cleaners like Liqui Moly work? Are they safe on the engine if there is a lot of carbon to blow through the engine?

I am getting a manifold clean soon [ not by mitsu]. Is there anything else that I need to request to be done at same time?

Hello!
I am new to this group and was advised to join over a suspected carbon build up issue... please could you let me know, when you guys have the problem to you have dash lights come on and does the radio also cut out?

I have a turbo diesel 2007 4 x 4 manual GLXR and I adore her, I have had her just over a year and she hasn't missed a beat until now.

So I'm driving along, the oil filter light and the alternator lights will flash and then the radio may or may not cut out, lately at the same time the ABS breaks and another light (!) will come on and then she will either lose power or cut out all together for a second or two - once the radio (or cd) comes back on she will start again...

The other problem is she isn't doing this every time, I can drive for a week or so and nothing goes wrong at all! She is currently with a diesel specialist and won't do anything for them that's wrong.

My mechanic suggested I ask in here as he thinks it may be carbon build up - I am hoping it's something easier as apparently if it is I will have to be hands on!
Thanks for any help!
Cheers!

Blondie :)

Hello Blondie

Sounds like your mechanic has some weird interpretations of how things work on a vehicle.

From what you have described, you've got some serious electrical issue.

Possibilities;

Faulty ignition switch or plug not making good contact on the switch

Always check your battery terminals, fuses and fusible links.

Connectors around ETACS area, may have come loose over time.


& if as your unit has many years on it, carbon build up will probably be there, esp. if no egr defeat has been implemented.

If carbon build up were significant the inlet swirl flaps may be buried in glug and choking the inlet ports at times.
Don't let the b'strds get you down!!

Thanks RHK Triton... I also have asked my auto electrician and he suggested the same thing about the ignition switch but changed his mind... I'll pass on your suggestions though as I am so out of my depth. I used to understand engines a bit more years ago but this is my first diesel...

First of all; Welcome :D :D :D

I'm wondering if it's not a combination of a few issues, Given the age of the vehicle, there will definitely be carbon build up. If the mechanic isn't familiar with these, he may only be suggesting the things that he knows are issues that need addressing. How is the economy? Has it been declining over some time?

As for the dash lights, I agree with everyone else; check earths, alternator output (over/under charging, spikes), load test battery, and check the ECU connections in the engine bay as well as at the ECU itself. Also check the connections under the drivers side of the dash.

Do you have any aftermarket electrical accessories fitted? Sometimes these can cause problems.

You have had the Triton for a year, was it an ex-Queensland car? Some of the flood damaged vehicles were sold down here. It may also be worth lifting the carpet and looking for water damage, if the truck has had a salt water immersion, the prognosis is not good.

Quick question guys, I'm about to do the carbon on my 07 3.2, 160,000Km, the question is. Do I need to replace any gaskets when I put it back together. I don't want to have it apart and then find out I need to wait a week to get the gaskets. In the PDF it doesn't suggest replacing any gaskets?

Hi guys,

I had a look in the intake and when I originally put the EGR tonys mod on the car had 35,000ks it now has 65,000 so in reality it should only have about 35,000ks worth of reticulation when I looked in it did seem to have a big build up where the EGR comes into the intake pipe should I get a manifold clean done anyways so I know its clean and will continue to be clean with the mod?

or for 35,000ks is it not worth it how much gunk should I expect to have in there?

Have you got a catch can on?? If you did not clean the manifold when the EGR mod went on then the oil that floats around will have something to stick to and add to build up.

Yeah I figured that might be the issue no catch can thats ok I will get a clean done and fit a catch can

Assuming the Tapatalk App search is legit, this thread currently has no mention of 'MQ' and no mention of whether installing a catch can voids warranty.

So ... has anyone cracked 100 thousand km in an MQ with the current 2.4L diesel? Or has anyone had any significant carbon build up issues with that engine? I've read a few articles that indicate changes in diesel fuel makeup, and changes to the current engine, plus a few other things, make EGR blockage and coking inlet manifolds unlikely.

Would be interested to know if anyone has experienced​ it recently, and whether anyone knows if it'll void the warranty installing a catch can?

Bit of a mini thread revival....

I finally have booked my Ml in to get the airbag and wiring recall looked at and I was informed that there was a third recall item. Apparently the ecu requires reflashing due to the carbon build up in the egr. This will assist with fuel efficiency, but I do have the option to not go through with it.

I can’t seem to find any information surrounding this recall, and more specifically much about the 3.2l having issues. My fuel efficiency is not what it used to be and I have always thought it was just rubbish fuel but I’m not really that concerned tbh.

Should I opt to go ahead with the reflash of the ecu or is it pointless to do? I’ve never had manifolds cleaned etc so I assume there’s build up but certainly not causing any obvious problems. A bit of guidance would be greatly appreciated.

Cheers

That's essentially why I posted the question. Need to understand more as to why they are reflashing an ecu for a 10+ year old engine and whether or not it is worth it considering the carbon build up is the real issue.

Hey guys

I have the SPV resistor unit and also a Western Filters catch can on a 2013 Triton. I saw this video recently and it brings up a few potential issues with 'tricking' the EGR valve to stay closed. My main concern is that the inlet air temp will be incorrect therefore the air density and potentially leading to incorrect fuel mix?

Has anyone throught through this potential issue?

In regards to catch can oil. I have had it on for ~5k and no signs of oil in the filter yet. Busselton mitsubishi said its unlikely the catch can will affect warranty unless it can be proven it lead to a failure.

This has been discussed before but, again, two things:

    1. Funny how he makes the assertion that the temperature sensor controls, or is used in other engine management functions but doesn't, or can't actually say what these are.
    2. Towards the end the real purpose of the video becomes apparent. That is to sell his ECU tuning service.

The reality is that changing that signal is, at least on the MN and ML, the best and safest way to achieve prevention of the EGR from operating and thereby clogging the inlet manifold.

For the MQ the situation is quite different. The signal from that sensor is used in other engine management functions which is why there hasn't yet been a simple solution developed that works.

If work is so terrific, why do they have to pay us to do it?

Thats a good point. But surely since it is connected inline to the MAF sensor (i think?) any change in voltage (due to the introduction of resistors) result in incorrect calculations in the ECU? I havent opened up the SPV unit but assume its a number of resistors.
