hi all,
I own a 2004 GU Patrol 3.0lt TD. 135,000km's on the clock and as yet no NADS modifications done . I would like peoples input on whether the nads modifications are worth doing.I've just started getting a high pitched whiring noise when the engine hits about 2100 rpm,local mechanic reckons it might be a leaking EGR gasket. I've thought about going the 6.5lt chev conversion route but really can't justify the $29,000.Love the patrol but don't want it to go bang.I know this topic has probably been done to death but there is so much info and conflicting stories out there that I'm totally confused.Any input would be greatly appreciated.

Cheers
Scrubrat

I may have missed it, but what does nads stand for and what does it actually entail??

I know it's not for mine (3.0ltr diesels commonly I'm assuming) but just interested.

And in English that means??????

In any language it means that unless you do the mods (NADS) particularly on the ZD30 DI, you run a very high risk of number 3 and 4 pistons grabbing hold of the cylinder wall and causing the motor to be replaced. KA BOOM!! capish? finito, end of story, finito la musica, vooshtabar.............. BANG!

If nothing at least fit catch can to improve clean air intake,more fresh air = more oxygen.

Hiya Tony, question: Do you think that the vapour from the PCV acts as an upper cylinder lubricant.
And do you think that after blocking the EGR, is there still a need for a catch can, as there would be no carbon to stick to the oily residue from the crankcase.
Cheers your Worship!! Rod.

I aint no judge Rod!

The PCV oil mist may have an upper cylinder lubricant effect but the negatives out weigh the positives. The reason for eliminating those vapours is to stop them coating the MAF sensor which can corrupt the signal the sensor then sends back to the ECU. The coating of oil on the inside of the intercooler also reduces intercooler efficiency.

How do I go about having the NADS done on my 99 GU 2.8lt TD?
Is it something I need the mechanics to do or can I do it myself?
Any links would be helpful.

From what I've read it only concerns the 3lt Di 2000-2003 and all Di, you might ask if the EGR block is worth while on your engine, I'd think so

Yep, block the EGR, easy, fit catch can ,easy, remove butterfly, easy. That's about all you need to do with the 2.8.
The main aim is to prevent oily carbon buildup within the inlet manifold and to help keep the Maf sensor clean.
