Blocking the EGR Valve

NZ Daz, You have more work to do, It's not just a matter of blocking the EGR, there are other important mods.
Boost guage, Pyro, etc etc.
It may pay you to do a search and read some of Tony's (Ynot) posts.
There is a lot of info on the subject.
Cheers, the ferret.

Cheers mate, I am a believer that you can never know enough about this kinda thing.
I have the boost gauge installed and the pyro is mostly done just need to do the hard part and actually get it in the exhaust.
I have read a lot of Chaz and Tonys info.
Will be looking at dawes & needle valves shortly.

OK, I may have missed it (a couple of cans has that effect)!!!

Is this mod OK to do to a TB42e???

i'm with you cliff read through the hole thing and still not sure (maybe i'm just slow haha) not sure if it's recomended on a CRD and from what i've go you should get a boost and pyro guage or a scanguage is that sort of right and what else should i look into please

Thanks all, makes sense will give it a go to moro.

Do you have any details on how much the economy actually improves--25% seems a LOT. Is something like that your experience?
BTW looks like you are talking about a 4.2. Anything on 3.0??

maybe a stupid question but wood this work whit an 89 mod gq diesel??? and if so do i doit the same as above ??

If you have a 2.8 or 4.2 with EGR valve, yes you can block it.
Some 2.8s don't have EGR (GQ)

This is what I did on my GU IV 4.2 tdi

First thing was to to make sure I could easily undo all the bolts that needed undoing, I ran a spanner over each to loosen them about 1/2 a turn, luckily they all loosened up OK without any skin off knuckles!

Next I undid the hoses to the intercooler

and removed the vacuum hoses connected to the intercooler, making a note of which hose went where

I then removed the 4 bolts that hold the Intercooler to its frame

With the Intercooler removed I could now get at the bolts that needed to be loosened to install the shim

After loosening these bolts a light tap and pry with the screwdriver and I had enough space to put in the shim

You can see it here partially in place. I coated the outer edges of the shim with a bit of high temp gasket goo.

The butterfly on the Intercooler was removed by undoing these two screws

You need to slacken off the adjuster screw to get enough space to get the screw driver in to the butterfly

Bolted it all back together and all seems well. Took me about 30 minutes all up.

I can now go and compete in my offroad comps on private land. Removing the shim would be a reversal of the above process, of course I will do this before driving on public roads.

Love it, well done mate.
