What a great read thanks to all for your knowledge
I'm sure the following comments may stir the Hornets nest on an old subject...........however!
Having recently purchased my first PATROL (2011 Wagon) and being a newbie to this forum, I'm must say that I'm horrified at the amount of negativity towards the 3.0ltr Turbo diesel engine.
If I had joined this forum prior to purchasing my first Patrol, I would most likely have purchased something other than a Nissan............
Anyway, the first step is to install NADS right, so down to the local 4 x 4 store I go to enquire about a Catch Can only to be advised that they are illegal?
So I have two questions :
1) I guess different states have different rules, but is fitting NADS actually legal?
2) how does NADS effect new car warranty
I would be very interested in forum readers views as I have always believed that the Nissan Patrol was pretty much bullet proof.
Regardless, we have been very impressed with our new purchase so far.

Catch Cans illegal?... Bullshit!
(edit... unless you vent to atmosphere)
If the can is inserted in line so the gases are still directed back to the engine they are legal
In regards your questions...
1) If your vehicle still passes emissions (which it won't if you block EGR) it is legal
2) Tear up your engine warranty (unless all you fit is a catch can, most manuf are OK with them but you need to check)
Dawes, Needle, EGR etc will all void warranty

G'day mate - yes you are right about reigniting a hornets nest.
Ok my opinion only;
I think in all states it is against the law to interfere with the pollution control equipment on a vehicle. Therefore blocking the EGR plate makes NADS illegal.
It is also illegal to have a manual boost adjustment in the vehicle so this also makes NADS illegal. Not sure about catch cans but probably illegal. Anyway there are enough points to make the fitting of NADS illegal. But, you must remember that these laws were to prevent people turning street cars into road rockets and not much thought was ever given to the advantages hat may be given to engine longevity. If you are a box ticker, NADS mod are illegal.
New car warranty; Again if you are a boxticker, the vehicle has been illegally modified and therefor the warranty is void.
However, if you want to be a realist, not just a boxticker, IMO doing sensible mods that are good for the reliability and longevity of the motor, and do not turn the vehicle into a weapon are a good and acceptable idea. As for avoiding warranty by using the fact that the vehicle is NADS fitted would only be a means to an end for the particular person/dealer. If avoiding warranty is the aim there are many ways of doing it and that would just be a convenient one.
A couple of other points. Firstly we hear a lot about 3ltrs detonating, but often not the background of how they were used or abused. Secondly, people who do not have problems don't write that on forums. I would have to agree that too high a proportion of the early 3ltrs had issues, but they are over represented on the various forums because as I say people that don't have issues don't write in. Issues often gather their own momentum as they are agreed to in popular media as well. Recently on this forum a member wrote that his dads unmodified 3 ltr had turned over half a mill k. I guess if it blows now everyone will say "there goes another one".
Lastly, if your is a 2011 model, you don't really have to do anything legal or illegal to the motor to keep it safe.
If your Patrol has been treated properly and you continue to treat it properly you should get a good long life from it.
Me, Iv'e got a 2005 GU4 which is just out of the suspect range and going great at nearly 200000k. If it does break well I guess thems the breaks.LOL
2005 GU IV ST 3.0. Snorkel. Roof rack. Awning. Spots. Welded I/C. Dual batteries & VSR. UHF. Barn door hinge extension. Roof top spot lights. Rear drawers. 2" lift. NADS. EGT and boost gauges. Trans temp and water temp gauges. Provent 200 catch can. Rear ladder
And crawling on the planet's face, some insects called the human race. Lost in time. And lost in space... and meaning.
Yes and when your 2005 GU IV DZ 30 Di motor goes make sure you replace it will some from that vintage or newer. Too many older recon motors around with their issues.Originally Posted by threedogs
Catch cans on their own don't change much if anything at all re pollution controls nor change the performance of the motor. So I would doubt they are illegal unless its called a motor modification by the various government transport bodies.
Agree,
Catch Can in line (as 99% are) = legal
Catch Can to atmosphere = illegal
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
Why bother with a catch can if it is going to atmosphere??
Ok some thoughts:
My ZD30 Di had a cracked head and lost coolant so I slightly scoured the cylinder walls. The engine still pulled me along with no noticeable performance loss in a 400Km trip. Day temp 42 deg C. Ok motor 168K km and I don’t know what its prior life was before I bought the patrol, (2005 GU IV).
Anyway after all that took in to my mechanic shop.
After some to and fro with our wonderful Nissan got one of the very few new motors.
New motor in vehicle.
Reinstalled:
EGR block, Dawes valve, Catch can.
Added
Glow plug timer set to 15 sec
Single mass flywheel
Heavy-duty clutch
Full metal radiator
Nissan knew what was going to be added. Seemed to be no drama with warranty. Anyway if it has issues some things will vanish.
After looking at the old motor I will say that unless you do the following:
Physically check glow plugs about 50 – 80,000 kms and if slightly crazed/chewed – change
At least at 100,000km physically check injectors.
Clean MAF about every 10,000km.
Recommend oil and filters change every 5,000 km
Also if you don’t have a snorkel, get one.
You will be surprised what will get in to the air box and put a hole in that paper filter.

The Nissan Patrols are bullet proof mate. Just not grenade proof. Lol.
My Direct Injection goes well. Really well. I'm just trying to save a much coin as I can for a TD42 conversion before the pin drops. Although it doesn't seem like its going to happen anytime soon. Which is good... Its the Di motors that cop the grief, not the Common Rails... Well not so much.
