Blocking the EGR Valve

[OhBugger]

I've just gotten to driving my new '99 patrol GR, and i'm planning on blocking the EGR, reading this thread, i've decided the pro's far outway the con's
Are there any specific tips for my model?
I've printed the openingpost and a plate will be made for my EGR, but do i have to change anything else after blocking the EGR? I've read some things about the butterfly valve?

Thanks in advance

neither of my 4.2 GU's have an EGR [1999 and 2000 utes]

My father has a 2006 4.2 TD intercooled, if we fit the blanking plate and remove the butterfly is there anything else to do in the way of adjustments ?

Generaly speaking, that's all you need to do to the 2.8 and the 4.2. (Block the EGR)
It is a good idea to fit a boost guage, that way you can monitor the boost and make changes if required

Thanks Ferret, do i have to remove the butterfly valve aswell?

And i think there will be a problem finding a boost valve on this island

Only the butterfly itself, not the whole valve!!

First priority however is fixing my brakes...

Do you also need to remove the vacuum line on the egr valve? (to stop it opening)?

I have noticed spots of exhaust soot on the intake runners. The blocking plate is fitted, with dawes valve.

Seems to happen at higher revs. Could the egr valve be leaking?

[the ferret]

Once you have blocked the EGR, nothing can enter the inlet via the EGR.
Just leave all the vacuum hoses as original..

If you have a leak from the EGR, then you need a new gasket, altho the flow through effect is reduced by blocking the EGR.
If the EGR is broken and jammed open or closed, it won't affect the function of the EGR block, once it's blocked, it's blocked.
