Closing the EGR Valve *check first post for links*

[Roguegir]

On my MN its before the cooler.
Brothers ML its in that spot with that hard to loosen bolt. It's been awhile since I looked in his engine bay.

Mine is installed in the same location, at the exhaust manifold, stopping the carbon before it gets anywhere

ML 3.2

I don't know of any 3.2's that had a cel from an EGR plate.

Read this thread after the blanking plates started getting fitted to find loads of 3.2's getting CEL's and limp modes.

my 3.2 with full egr I get cel and limp,
with throttle body unplugged and ffull egr plate i get cel and limp
with throttle body unplugged with full egr plate and non functioning butterfly valves in bottom manifold i get cel but no limp and massive performance response.

Hi all, back on again after many months.

I thought I had an egr problem around christmas when it was surging and wot not. Turned out it was fuel filter not egr. (I dont have mine closed....just gonna put the 10yr warranty to the test)

some food for thought after reading the last few posts......everyone knows egr is to reduce nox and it does this by reducing the temperature in the engine. so just putting it out there.......metalic materials strength and fatigue properties generally reduce with increased temperature. Now i doubt that you gonna bust anything because of egr blank plate, but if you do a simple explanation like this from mitsi engineers can put your warranty claim down the tube and you will have to know your shit or have some $'s to go to court to dispute it.

again just saying....everyone seems so sure that nothing will happen if u blank the egre....but cannot no for sure. I completely agree that dirty exhaust into your engine cannot be good....but mitsubishi and many other car designers do this and warrant this.

anyway....just something else to discuss. lol

My blank is pre cooler and used to throw CEL's. I added the one way valve which sorted it out till the cheapie valve failed. I have since fitted a home brew valve and lengthened the hose prior to the valve to about 300mm. I know the home brew valve doesn't open below 5psi so it probably isn't helping to equalise the pressure. I think it's the 300mm of hose that is helping to avoid CEL's.

It makes you wonder if you could just fit a small reservoir of air to the 'T' piece to fix the MAP line low pressure?
It would need to be able to handle 25psi but could be quite small or a small length of hose like yours just blanked off?
A few CC of volume might be enough?

I can my 91 nissan terrano 2.7turbo has no egr crap, the engine good for 400k+ thrashed every day and loves it
new common rail diesels are throw away engines
the isuzu bighorns 3.1 with egr ended up scoring the pistons and bores ultimately needing rebuild.
if you seen the state of your intake ports first hand you would block it

when i thrash my triton which is raising my egt and internal combustion temp where is the egr cooling effect then? there is none cause it turns off.

[koshari]

does anyone have a scale template for making up a blocking plate for a 3.2?

[Kegsy]

Just copy the gasket ...

[koshari]

i wanted to make the plate up at work before i pull the gasket off.

[irwazza]

I can Scan the one I got from chipit if that will help?

You could include the measurement centre to centre for the fixing holes in case the scale changes?

[irwazza]

If the scale changes yep, does that mean I need to get off my ass?

Only if you can't reach a tape measure.

[Cowboy Dave]

Depends how far away your scanner is...

[irwazza]

The scanner is close enough, it's just the plate is in the shed

[koshari]

its ok kingbrown sorted me out, all is good. thanks all the same.

[irwazza]

Did he send you a scaled image? If so you should share here for all to benefit from

how do you attach a pdf?

PM it to me if you like.

Since being able to switch the throttle body valve to wide open i've got a couple of fuel consumption results.
Small improvement and early days but at least it's not worse.
The last 4 fill ups were,
8.15L/100km - pre mod
8.15 - pre mod
7.94 - used for about half a tank
7.92 - used for the full tank

About 3% better economy. So it looks like a small gain there but the other gain is in the response and ability to take it down lower with smoother results. 60kph in 5th is viable instead of a bit of vibration as it complained before.

Hi mate
I've beem reading your posts with intrest.
I've a ml can you post a final mods or how to on the fixes that you think are
The best for our Ml's and mn's
As this thread is long and hard to decider tah

Hi Graham,
I'm assuming you have an unmodified 3.2?
I would get a Scanguage type of instrument first so that you can remove any codes 'if' they occur? Good fun anyway to be able to read lots of info live as you drive.
Next would be the EGR blanking plate.
That's a good start as long as your manifold isn't already chocka?
