Welcome to NTN mate. You passed with flying colours

[Kegsy]

Okay, so confirming, it DOESN'T go just below what I think is the actual EGR valve (which is passenger side of engine, up top right near firewall, NOR does it go on the end of the pipe directly underneath that ..

but on the heat shield section that is closer to the front of the vehicle, more kind of in line with the battery.

have I go the right place now?

(and do I ask why it's better to go here rather than in the other two places?)

Thanks again,

(I'm trying to learn as fast as I can, sorry about the slow learning to those of you whose minds more easily grasp the mechanical concept stuff!)

You got it champ.

Better in that spot as it stops the cooler filling up with carbon

[RHKTriton]

Wonder what usefull things you could do with that cooler?

Oil cooler, water heater, ......?

[NTBB]

Just out of interest, what's the problem with the cooler filling up with carbon..

[Longranger1]

I think blanking the outlet side of the cooler makes sense as it will stop coolant leaking into the intake if it decides to let go. Rare, but it has happened with other makes.

Hydraulic lock = trashed engine. Not very happy making, but easily prevented.

If you are really anal, block the inlet side as well. Not much gunk should build up anyway with no flow through the thing.

Ben I can quite gladly make a egr plate for your triton, its me you were talking to today just flat out ATM! But can point you in the right direction etc out of hours haha

[odie602r]

Hey that would be awesome Tuff Troop (do we use real names on here if we know them?), in my mind the sooner the better 'cos as you would know it doesn't have many k's on the clock at the moment and I'm keen to keep the insides clean.

But, I did read that you are flat out right now.

What's best here, to PM to see if we can sort out a time? I'm willing and keen to learn how to tinker with this beast to make it an even more enjoyable 4wd.

(I think I'm still confused re where to blank, I know I asked you twice today to show me, but it still seems to be in a different spot to where Kegsy described??? )

Ben

[Kegsy]

Seems to be differing spots for everyone ha ha....

Most people I've seen blank it where I have done. That was the spot in the original info going around here.

But Pete must have done his on the outlet to the EGR cooler box.

As long as ya pick one of them on that EGR cooler you'll have stopped the flow

[NTBB]

LR that's a good point, I do recall some members having problems with corrosion in the blank which they thought may had been caused by condensation sitting on the blank in that position.
I have had my blank in both spots and have yet to see any signs of corrosion (80k+)
I'm just wondering why carbon build up in the cooler would be a problem it's just a s#it load easier to install the blank after the cooler IMO
This is in a ML, no idea about MN's

[Longranger1]

The egr cooler could be utilized as a camping hot water heater. But you didn't hear that from me .

Haha! I thought of doing this too but not sure if it would cause it to rust out over time? Do you know if the internals are made from steel or copper? Great if its copper.

[Longranger1]

I think it would be stainless but not sure TBH.

[srb]

Stainless would be ok to. When I do my modifications i will check it out. Hope to finally do them over the easter break. will let you know how it goes Pete.

[RHKTriton]

Bl**dy good point LR.

Apart from "genetically" modifying our trucks to die from asthma, have weak steering columns and saggy bum syndrome, amongst other things, we now have the potential drowning grenade!

The thermal stresses that the heat exchanger is exposed to could possibly cause a leak over time (probably in year 13 of ownership).

A blank downstream would be good insurance.

Would be good to be in a country where you pull all that garbage off. Save time on servicing, reduced weight, etc.

Okay thanks Kegsy and others.

(as a reminder I have an MN 2.5 MY12)
I've now received my EGR blank courtesy of GLX-R Alex (thanks again!), and now know the preferred place to put it is under the heat shield section near the battery (not the other two sections at top and bottom of engine near the firewall).

I am now ready to install it (Scangauge is on it's way in case of an engine code) and have another clarifying question ...

Do I undo the two nuts and place the blank on top of the existing gasket, then simply do back up? Some people on here have reported splitting the gasket in two and placing blank in between, others to place blank on top with some sort of sealant, and other have reported just slotting in place and tightening up.

I just don't want to stuff it up ...

Thanks in advance,
Ben

[snowman]

i don't have 2.5 but i slip mine in on one side of the gasket and no sealant. do up reasonably tight. no problems.

sealant would make it a pain in the rear to remove again in my opinion.

nuts can be pretty tight the first time. don't over tighten doing back up.

[biggibbo]

I put mine underneath the metal gasket - don't use sealant as it will make it a pain to remove.

[helicoptercow]

instead of splitting it, why not just go buy a second gasket?

easy

Ben, you really can't stuff it up... It doesn't really matter if the gasket is on top or the bottom and no need for sealant. I Just had mine off while I did LR's EGR bypass and the blank plate had no sign of leaking. And it doesn't matter if you put the blank before or after the EGR cooler. I personally prefer to have it closer to the fire wall after the EGR cooler for the reasons LR explained. Have you got a chip? or tune? If not you may experience the odd CEL or limp due to the slight negative air pressure. Easy way to get around this is to tee a one way valve into the map line. This requires a small tee piece some tubing and a one way valve from your local aquarium shop. I did this long before I installed my chipit and never had a one CEL or limp.

[Sky Miner]

I agree with LR... + im to lazy to go and dig that far into the engine to put the plate up the front where most ppl like to put it
Ahh it works.

[sierra]

It doesn't matter where you block off a pipe, the result is always the same, the flow stops for the length of the pipe.
I would and have, put the blank in the easiest spot to access.

[odie602r]

Got it done, some 1.5 hours later (after dropping a bolt, not finding it, getting a replacement from the dealer, wrestling trying to slide the blank in, then having the bolt drop out when I reversed out...)

Anyway, it's done, scanguage on the way this week just in case, then save my coins for a Chip It chip in 6 weeks or so. I, like others, have noticed that the turbo lag seems to have almost gone now. Amazing really.

Thanks for everyone's help, suggestions, and pointers, it's been extremely beneficial and I couldn't have done this job without it (even though it's probably relatively simple).

You guys rock!

This is the place to be.

Okay, so with full EGR blank in, is it normal for fuel economy to worsen? On a highway (100kmh) trip yesterday of about 250kms return the MN used almost half a tank.

I haven't refilled just yet to get an exact calculation but mine on a highway normally gets 9ishL/100kms.

I was expecting fuel economy to improve based on reports from here ....
