You may find your EGT's will climb once you fit the blanking plate to the EGR, but you have the guages to monitor the situation.
The temps you have reported are pretty consistent prior to the EGR block and in my opinion are normal.

whats is this NADS i keep reading about?
sounds like a little bit of a problem is not attended to?
does it need to be done?
sorry about all the questions but as i have just got myself a GU 3.0ltr im trying to find out as much info as possible
Easy peasy mate.
NADS: nissan anti detonation system.
The process of blocking the EGR, removing butterfly on the intercooler pipe, fitting a catch can, boost gauge, pyro (exhaust temp guage) and maybe a few other bits and pieces.
Because the ZD30 is prone to self destuct by way of melting pistons because of a design fault and other things, if you "do the nads" you will enjoy a very prolonged life of your ZD 30DI motor.
If your motor is pre 2004, I would be looking into doing the NADS fer sure.
There is a heap of info on the subject on this forum, just do a bit of a search and all will be revealed.
If you can't find it, just ask, there are a heap of like minded folk on here that would be happy to help you.
Cheers, the ferret
thanks mate.
The old fella that traded my 4x4 in at the car yard has done alot of mods to it.
I have the boost gauge, no pyro YET.
but how can i tell if anything else has been done? im not to mechanically minded lol.
NADS sounds like a must do thing for my 2001 Patrol :)
Yeah, there are a few things you can do to get a good run out of your motor, first, check to see if the EGR has been blocked.
Tony "ynot" on here has posted a lot of very good info on the subject, as far as I'm concerned he is the guru and I have found no fault in his recommendations.
You need to block EGR, clean MAF sensor, inlet manifold, fit catch can, boost and pyro guages and in some cases a dawes needle valve or manual boost control.
It all sounds confusing and expensive, but by doing these mods, you can drive it hard and not have to worry about a $6000 rebuild any time soon.
As I said before, have a look around on the forum and you will find
a heap of info pertaining to the ZD 30 DI, aka "GRENADE" motor. other than that, post away mate.
Cheers, the ferret.
As I sai mate, some thing might be done already when I got it. The bloke who had the car has done a fair bit of work.
How can I check to see I anything has been done? Or should I get a mechanic to look it over?
You could ask the bloke ya bought it off, and if unsure, yes take it to a good mechanic.
The EGR may have been blocked.
Robson Bros in Bentley is where I would take it as they do these mods.
cheers, ferret
Yeah I got it from a car yard. But an old bloke had it, so I don't think I could find out mate. That place in Bentley sounds good. Might have to give them a buzz! Cheers
Ok so i went to Robson Bros, and i do not have a Dawes valve for the EGR fitted. Is going to cost me about $340 to get one fitted.
also to get a Catch can fitted it will cost me about another $550 roughly.
apart from these 2 and the 2 gauges, is there anything else i should be looking at?
the bloke down there was very surprised to see my troll with the Gas Diesel Injection, any reason why?
cheers all :)
You can buy the catch can for $185 + postage. All you will need is about $25 worth of pipe, reducers and hose clamps to fit it. $550 to supply & install seems a little high.
Dawes valve is ~$70-80 (I think) and again only a few dollars in tubing to fit. If you also need the EGR blanking plate fitted, and the adjustment to the turbo screw (forget the correct name) then $340 is probably reasonable.
A pyro or EGT (Exhaust Gas Temperature) gauge is essential as many feel that excessively high exhaust temps are the first sign of problems, and this allows you to keep an eye on them.
