Is there any concensus on which pillar pods are better than others?Quote:

I think they are illegal on cars not 4x4, cant see why as by law now you need the GPS on the right hand side .
anyway sending a PM regarding pillar Pod
heres mine others have Autron $$$ good gauges and multi function as well
Thanks mate, this looks the goods!!!
Got your PM too re legalities etc. Appreciate the help
I have the same ones as threedogs, very happy with mine too.
Hi guys, been looking on alot about the 3.0 as they seem to suit my budget and only the GU series body style appeals to my, so im pretty set on a 3.0 engine, and i guess doin mods is always gonna b part of the plan anyways, regardless of what car/engine lol
So anyways, can someone break down what exactly is needed, or mods to prevent engine failure, i gather that once these preventative mods are done, the engine should last the life time, as it address the major concerns with engine failure, or catch it before it goes bang
From what ive read, so far it is:
-EGR block off
-Oil catch can setup
-Boost/exhaust temp gauges (Where is the temp sensor best location to mount it? Right on the dump pipe or before the cat?)
-Dawes and Needle Valve (This simply a boost control method to stop over boosting?)
-Larger Intercooler
Am i missing anything else?
cheers
Go to the manuals and software section and have a look at the Nissan Patrol reference document, it will tell you everything you will need to now.
Nah that's about it temp, sensor is about 100-150 after the turbo.
Intercooler should be ok but saying that if its oily its leaking, you could remove the IC and clean it with petrol or similar
make sure its dry before you install it. Pressure test it when it out, don't use compressed air , bike pump ok to see if leaking
For me the jury is out on a larger intercooler, do you get $800 worth of extra cooling[lower EGTs] over a tigged OE one, you decide
I think its $800 I could spend elsewhere, but that's just me
cheers guys, cant access the pdf as not enough post, but if that seems to be all the parts, than GU is the car im gonna end up with along with these mods.
I cant believe how much a off the shelf IC kit is!!! LOL... can prbs make my own kit for 1/3 the price and thermo fan setup, jesus, the guys selling these kits must b laughing with how much they sell em for haha, but agreed, id rather spend the extra money on better tyres or even a save up for a front locker
anything after 04 you should be right but plenty here with earlier and going fine just do it.
too many get Paranoid over it, Since Ive been here only 2 have gone boom and one was a Cr.
more talk I think
I agree with 3Dogs on this one. My old Patrol was a 2001 model, bought new and modified for outback work. That car was heavily used for some hard work including towing, first an Ultimate Offroad Camper and later a Supreme Getaway offroad caravan.Quote:

2. Cooling: My Patrol had a Nissan bulbar and a low-mount winch. I always made sure there were no restrictions to airflow in through the front grille. May of the cars that have blown engines have had high-mount winches fitted that partly restrict airflow through the radiator
3. Snorkel: These cars greatly benefit from a well fitted snorkel as it improves the flow of cool fresh air into the engine
Again, I agree with others on fitting the gauges (boost and EGT) to see what is going on inside the engine but have to say I think replacing the Intercooler "just in case" is a heavy handed approach. If there is genuinely nothing wrong with the IC, why replace it.
The $800 - $1,400 a replacement IC can cost you are in my opinion much better spent on other things.
imho I think the grenade thing is way over rated, any time something goes wrong on a ZD30 they will say its grenaded even if its something else entirely.
Hi my 3ltr went bang and am looking to convert it to a 4.2td. The GU 4.2TD is way out of my price range so just windering if anyone has put a GQ 4.2TD motor into a GU. I have heard that the GQ motors are great just wondering if its worth putting 1 in my GU though? Any info would be great thanks
I agree here mate. Hows this. I got an email from a mechanic who has a 2009 CRD and its holed two pistons!!!! Possibly from an EGR failure. Hows that!!! Block that chit and be done with it.....Quote:

Hey Mudski what happens when the egr fails?
How did that make the engine blow? and is that something we should look out for?
From what I was told from the mech that the EGR failed, so it was either an electrical issue or mechanical within the EGR. So I am only assuming that the EGR stayed open too long and increased the cylinder temps way too much and basically melted the piston. Or heated it up so much that it structurally failed. Another reason why we block those bloody stupid things off. Not just because of fouling up the intake alone.Quote:

I have wondered if any of these type of threads would exist if EGR's were NOT put on these engines from day dot. There is more than just one factor to a grenading engine, like no egr blocked = high cylinder temps, shitty ECU control of turbo boost = engine having too low a boost level( rather than too high) there for increases cylinder temps again. Mix these two together and you got a big issue I reckon.
thanks for all the info guys, im posting in this tread so i can easily find it and refer to it in the future.
Pretty sure legalities of this are not good, you cant put an older engine into a newer car. You can only go the other way around...Quote:

You need to match the year or better, its all to do with pollutionQuote:

Help me plaese I need this mods!!! I am Paul from Honduras i have a 2003 patrol and its going very bad, i blocked the egr but it stills ruining my maf sensor i have bought 7 sensors till now and i dont know what to do please help me
Very true my 07 hilux blew up at 160k never missed a service they said I hadn't been servicing it. Then after my mates did the same we looked into it and found out heaps had failed they just keeping it quiet. Unbreakable my assQuote:

That is every 50 – 80k have them physically check and if they are crazing toss them and replace.
good read..
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
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.Quote:

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.Quote:
