Default GU diesel problems?

Hi everyone.
Im new at this so please bear with me.
Im seeking info on the reported failures of diesel engines in earlier GUs.
I need to update the old GQ and am looking at 2002-2005 diesel auto GU to tow my 20ft van.
Is the reported problem real?
If so has it been fixed?
From what year/model can I safely buy?
This has probably been done to death already but I cant find it anywhere.
Ive looked through the forum as best I can but cant find anything.
Any help would be terrific.
Many thanks.
Tinman

There is a fair bit of this info available on the forum but in general from what i have heard:
- Stay clear of the pre-2003 3.0L as they are more prone to blow-up.
- The earlier ones also had problems with the spline on 5th gear
- The common rail direct injection models with auto can have fuel consumption issues
- The belt tensioner has a tendency to go - if it squeels when u start it up it might be on the way out
- Can get cracking on the barn door with the weight of the tire
- Can get cracking on the roof gutter if has had roof racks with a bit of weight
Thats about all I can think of but do a search Ive sure you will find more.
Cheers, Luke.

Buy a 4.8 petrol if money is no object.

if money is an object, buy a 4.2 GU

I have a brand newie can only assume it goes about the same or a little better than previous models. I have a heavy boat and the 3L can't tow jack. The car is ok by itself but the moment you start adding decent weight it cry's for help.

Go 4.2l or the 4.8l

Thanks guys. All info is helpful.

Hey Luke001, what happened to your 2003 3.0L that you say R.I.P. to it.
Engine didn't blow up did it?

I,d still like to know more about the general problem and haven't yet found any reference on the forum. Bur then my search skills aren't that great.

Thanks anyway
Tinman

If you look at a few posts by white, chaz or 5upamav you will see how to bulletproof the ZD30 of any year.

The main problem with them is a nasty combination of:
- a mix of EGR soot and blowbly oil creating a tar in the intake manifold restricting airflow to the cylinders
- oil contamination of the MAF sensor creating an incorrect signal to the ECU which raises fueling.

A combo of a lack of air and too much fuel will destroy any diesel engine.

I have always found the Di ZD30 a far more responsive engine than the CRD version, even though it supposedly has a flatter torque curve.

As for a 4.8 you will need a tanker if your towing, 130L of juice will get you not much more than 550kms if you have a loaded truck and van. I was close to buying a 4.8 Ti new last year but didnt, beautiful vechile but not really good value for money considering its lack of gear. Either a yank pickup a few years downtrack or a 200 4.5TTD with a better auto.

If money is not that great of a concern get a 4.2L 1HDFTE LC100 auto or a 4.7l V8 LC100 auto. These are the best tow vechiles in australia bar none and the V8s are cheap as chips. Nissan prehistoric museum piece 4.2 is pitiful compared to LCs.

Hey Benno. This is the NISSAN Patrol forum. I don't think he will get a 100 Series Cruiser for the price of a mid naughties Patrol. As for the 3 litre diesel, refer to your avatar.

If you havnt driven a LC100 V8 or 4.2TD then you dont know what your missing out on.

Checked the price on V8 100s?

But they are thirsty like the 4.8 and don't have as much grunt as the 4.8. I think you should double check the figures before bagging patrols on a patrol forum and saying "These are the best tow vechiles in australia bar none" On a recent trip towing a 17' van I was all over an f250 with the powerstroke twin turbo v8 diesel and his van was the same size as mine. I think the 4.8 patrol is one of the the best tow vechiles in australia bar none!

100 V8s are more economical than 4.8 GUs, I have written many times before but once again, the 100s 4.7 V8 only has not as much torque off the line as the 4.8. On most hills the 100 will be in 4th and 3000-3400rpm where the patrol will be in 5th. Given the very smooth nature of the V8 its not a problem.

"Is one of the best tow vechiles in australia bar none" hehehe

Im not surprised you could hold a 6.0/6.4 powerstroke, it had probably thrown a code, seriously.

2002 Toyota Landcruiser GXL Power 170kW @ 4800rpm, Torque 410Nm @ 3400-3400rpm 16.4 (l/100km)

2002 Nissan Patrol ST GU III Power 185kW @ 4800rpm, Torque 420Nm @ 3600rpm 17.7 (l/100km)

I can live with the 1.3 litres per/100 difference.

Are you comparing the same years? I am.

smooth nature of the v8????? lol, have you ever been in 4.8 ?

Yep, now drive them in the real world. The 100 will be ahead by around 5-7L towing on the highway.

If you think a 4.8GU is smooth you could not have driven a 4.7 100s.

This is not really a very good introduction to the forum for Tinman. He has asked for our advice and has received instead a slinging match between one make over another. He has requested information on the 3litre diesel problems in the Patrol. All I have heard is that the "problem" was fixed after 2003. The only problem I now see is that all new Patrol diesel wagons sold are only available in 3 litre CRD.

This is not a slanging match.

This is

As for the problem, it was not fixed after 03 but occurences of failure are less.

OK. I will end my comments here. A vehicle the size and weight of a Patrol is totaly underpowered by a 2.8 or 3 litre motor whether it is petrol, diesel, turbo or not. They have to work so much harder that premature failure is almost guaranteed. My TB42EFI is no powerhouse, but it has 325000 origional ks on the clock, and I cannot imagine one of the aformentioned engines lasting that long.

O.K. Sit back and wait for the flack.

Yer bloody thing craped itself. I did roll it sideways down the freeway 3-4 times at 100km/h so that probably had something to do with it. Was a great truck though, never had any problems with it till i killed it. I think if you get a 3l, just get one that is post 2003 and take a look at the referance doc and you'd be unlucky to have any problems.

If you are keen on a diesel Nissan and don't mind spending a bit extra get a 4.2. I personally feel they are more reliable and found the 4.2 easier to live with offroad which is what I brought it for. It does use a little more fuel than the 3L though. I used to get around 1000k's out of both tanks with the 3L but only got arount 800 with the 4.2.

I didn't use either of them to tow with though so I can't really help you with that side of things. I think either would do the job OK but they are quite slow trucks and don't have a huge amount of grunt so I don't think either would be my personal preferance as a towing vehicle.

Oops just noticed you where after an auto, so the 4.2 will be off your shopping list. They only came out in manual.
