Well, I guess it's official - MN manifold changes..

[Fnordy]

variables...
- A female prime minister - no wait, britain had that
- Driving on LHS of the road - no wait, some european countries do too
- it gets pretty warm in spain
- all it leaves is excessive beer consumption really

Must be that!!!

[Longranger1]

Damn... I didn't think that!!! What about moon phases, tides etc. Bloody variables getcha every time.

[patrolus]

lol. we got a female chancellor in germany as well.......must all be her fault!!!!
but keep in mind that there is a lot of differences when the car gets build. if mitsu can safe $2 because we do not need one part or they can use a cheaper part instead and still comply with the local standards ---then they will do so. i used to do some work for mercedes benz back in the days and every car was different (dif exhaust for the usa for example) depending on destination. and they run off the same production lane. just variant a or b or c. not a problem nowadays....
so they look the same but there are differences.

can anyone show a photo of the EGR valve on a MN 2.5

[gregned]

cowboy posted one not long ago try a search on his posts it was from the manual too quite good.

[Snooozy]

Just to apply some science to the problem

if in the southern hemisphere the water goes down the drain in the opposite direction to the northern hemisphere

maybe the problem is that the fuel/oil /air is going in the wrong direction & causing the problem.

if they re-build the engine completely reversed...problem solved

the answer is so simple

[Fnordy]

I'm with snoozy - didn't even think of that, but we have gone seriously off topic...

[Tony]

Maybe we should come up with a new crank, block casting and put two side by side in a V formation Imagine over 270kw and 800odd Nm. Then see if one side carbons up.

Guys,

I don't understand why the ML Triton's have had such an issue. Is the 3.2 Did engine in the Triton the same as that in the Pajero's, as my 2005 Pajero had 225,000 km's on it when I sold it and never had any issue's at all?

Yeah that is correct the only difference is that the ML tritons have a normal turbo while the pajeros have a VGT (Variable Geometry Turbo) The pajeros are even having the troubles too just not a frequent

[MitsiGuy]

There is a hotline fix for the ML 4D56 which is pretty much the same. The new manifold is exactly the same except the boost nipple is moved closer to the throttle body. Pre EGR. ML15-004. The joys of the new manifolds is that they are on restricted backorder to my knowledge. So its good luck getting one atm

[destorman]

My mechanically challenged technically impaired mind seems to struggle with the notion that a multi national vehicle manufacturer is only having trouble with 'carbon build up' in Oz ... if that is the case, the variables are:

Sorry ... didn't notice this had posted ...

Variables (between Oz and European Triton usage):

- Temperature (which affects both fuel and engine performance)
- Roads (affecting load on engine and fuel efficiency)
- Fuel ('additives' will be different)

The solution ... perhaps an Australian designed and built 4wd?

now who would buy that

I would buy an Australian 4wd if it had a square drink holder for my Farmers Union Iced Coffee

Just had a look at the exhaust manifold on my MN 2.5. there are no pipes or tubes going from the exhaust manifold to the intake manifold ,that basically is EGR ,exhaust gas recirculation ,there is no vacum operated diaphram that regulates the gases into intake manifold so what I am saying there is no EGR on my MN 2.5 4wd . if some one has photos i would like to see them

[gregned]

There is no vacc operated egr on the mn it's motor controlled don't have pics but have seen them on here but lift the bonnet locate big radiator hose on passenger side follow it tossers the back an keep going beyond the end of it you will see a black cap with 3 white dots on it that's the egr valve

[CairnsGSE]

pulled the intercooler hose off and had a look inside ,yep can see the port where the exhaust gas is entering manifold

[Tony]

After all this time (60k) I'm in for the revised manifold all under warranty regardless of whatever mods..

The revised inlet has the MAP port just behind the throttle body rather than in line of the EGR and near the plenum section. Much better set up as will get the cleanest and most stable air .

Even though I have the EGR blanked the dealer is happy to upgrade my manifold as a hot fix for strange boost codes that can occur even running stock as a rock.(No Chip, no blank)
P 1298 VGT system high pressure
U 1437 Dynamic range error
U 1430 Dynamic range error

symptoms... Pull like a train then power slowly drops off accompanied with increased smoke and rising EGT's Back off and jam it, same again. On a full throttle with high RPM /high load can go limpy. Higher fuel usage, surge shudder etc

Surprisingly mine still has some crud mixed with oil mist in the map port. ( May be something in the provent idea) No issues with warranty over the EGR thing, but was recommended better removed so no one sees it for the warranty work for the legal eagles Happy to pop it back in for off road use only.
In the dealers experience, the 2.5 manifolds don't seem to coke up like the 3.2's due to much improved down draft design and air/port velocity. Just the MAP port. Happy to be proven wrong

I'll get them to do the tappets wile in there as involves removing injector pipes and manifold anyway. Better than disturbing it all again in the short term.

An idea of what we're looking at......

Any idea where I can get an EGR blanking plate from??

The EGR exhaust gas is routed through the cylinder head similar design to the hilux. You will see the pipe from the heads EGR port going to the cooler then to the EGR valve. So you won't see the pipe on the exhaust manufold like the ML. The MN has the cross over port in the front of the head.

[RHKTriton]

Luxs are just another granpa vehicle like the Camry, etc so they probably don't notice the engine getting sleepier...he eh e doodi boy.

My Vito and Pug didn't seem to have any issues with Carbon, but if you trawl the web there are others having problems overseas.

The whole EGR setup is a design disaster. This is why manufacturers will probably all eventually move to the urea additive setup - less pollution and more performance.

Re economy - I suggest our roads are a big problem. Should be flatter, longer curves, less intersections on main roads minimum speed limits on freeways and higher overall limits on good roads. Larger diameter round abouts would improve flow also.

Anyway all have a happy and safe New Year.
