Blocking the EGR 3.0TD

[Andee]

G'day

I have a 2005 GU that is pushing 200,000k's
It has been the work truck pulling the trailer since new.
I have just got it back from removing the cracked Dual Mass Flywheel and now runs like a tractor!

Anyhow,
I have been following the posts on blocking the EGR, makes sence to me. Can I block it with the plate and leave it like that for awhile as a trial? and for how long?
I fit a boost guage when I first purchased it as I never owned a turbo engine before and wanted to see how/when/why the pressure dropped away.

So the plan is, block the EGR and watch the pressure guage, the fuel guage and the temperature guage.
And if someone could describe the position of the adjustment screw for maximum boost?

Bump Can anyone help Andee

Over in the forum section under engine drivetrain
whole piece on it

I would be fitting an exhaust gas temperature (pyro) gauge before you do any othe modifications, it will tell you a lot about what is happening inside your engine.
You can try fitting the blocking plate without adjusting the boost but be careful and keep a close eye on the boost gauge.

The first photo shows the VNT adjusting grub screw (red arrow), do NOT adjust the VNT actuator rod (blue arrow).

The second photo shows the EGR valve down the RHR corner of the engine bay (note the location of the fuel filter for reference) with arrows showing the 2 positions where the blocking plate can be fitted although I personally think the top position is easier to install.

Thanks for that YNOT

Will be fitting the EGT shortly.
Ran the overboost test as per the manual, only over boosts sometimes, but definatly does and loses power when flat to the floor.

Thanks again.

tony the 2 photos you have shown are they the same for the GU III ? and how hard is it to lift of the intercooler to get to the EGR valve also i read some wheres that once the EGR is blocked it is a good i idea to remove the baffle plate going to the intercooler????


part 2 finally worked it out and have i believe blocked of the EGR valve at the top as in the picture the question about the baffle still stands tony??? once i had worked out where i was i the hardest part was linening up the bolt holes with the EGR the plate and the metal gasket. found it easier to feed the plate diagnaly from top right to longer left then aline the right hand holes first and only threading the bolt in part way to allow movement to aline the bolt holes on the left.

seeing as i am a first time owner of one of these and this is the first time i have solo on DIY front on it it was a little worrying for me test drive went fine and seemed to have a bit more get up n go,,,,,, or it could have just been in my mind :)

It should have a bit more get up and go because you're MAF voltage would have increased slightly and you should have more oxygen in the cylinders to burn.

There is no "Baffle plate" in the ZD30 Patrols intake or intercooler. Only the Navara and 4.2 Patrol needed a butterfly valve because they had pressure controlling boost unlike the ZD30 Patrols vacuum control. The butterfly valve would close to reduce boost or air flow as the EGR valve opened.

thanks for that bit of info as you can see i am still learning my way around the beast :)

Those photo's are of a GUIII, all ZD30Di should be the same.
The intercooler is easy to get off but as Chaz said you shouldn't need to.

Hi, I apologize for my bad English but I'm using the automatic translator.
I have a 3.0 Patrol, a mechanic not very good blocked the EGR and changed the VNT actuator rod length, now let me bring it back to its original position but do not know how because the mechanic did not remember how many rounds has changed length.
Can anyone tell me how to bring it back to the origin?
thanks
