Crayman,

From this forum, it appears that the series III motor in the 3L TDI has been sorted for any probs.

I also have a 4.2TD GQ and I must admit that I don't drive it like it's mine, but it just takes it. The donks proven, a little aged and primitive, but that's what I like, you can still work on the friggin' thing without getting into too much trouble. The running gears the same, suspension is tried and true and the trucks on got EGR fuel now, everything else remains mechanical. I have just ordered a TDI DX 4.2 wagon.

The 3L is quicker, but the motor remains to have been tested like the 4.2 since 1988. My motto was stick with what you know. Get some other opinions and take it from there...

Cheers mate,

Chris.

how long do you intend to have it? if you want to run it into the ground over the next 10-20 years go the 4.2 if you want to keep it 3-5 years the 3.0 should be ok even if they have fixed the 3.0 you might get 4-500k out of it but with a 4.2 you know you should. btw no mine vehicle I have seen gets 400k because the bodys are well and truly gone before that

I have the 3 litre series111 with dtronics I'am rappppped with it. Member Roachie (4.2TD Patrol) was back to 4th on the way back from Berri towing similar weight but he had a roof rack Mine was quite happy in 5th but who knows what total kms they will do. Cheers from Paul

Gerk is quite right. I was reading something yesterday about the difference a D-Tronic can make to the amount of torque a lecky-controlled donk can produce. My 2000 model produces 330nm, the standard 3Lt produces 354nm. The newer 4.2 TDi has a figure of 360nm. The D-Tronic is supposed to produce around 400+ nm....No wonder Gerk was cruising in 5th into a strong head wind while I was struggling in 4th.
I must admit, I am envious of being able to plug in a large power increase. I've done a few things to mine to help it achieve better figures (like a 3" free-flow exhaust and full injector service etc etc). The only other ways I can increase power on this donk would be to add an intercooler and maybe a bigger turbo....but then reliability could be a problem.
As I said, I'm starting to warm to the possible idea of electronic-controlled donks......ON THE PROVISO THEY ARE BULLET PROOF..... I'd also like to see the 3 litre type, but with 2 extra pots on it (4.5 litre)....and a cast iron guarantee that Nissan have definitely solved the blown motor sysdrome. Whack a D-Tronic on that little sucker and you'd have about 550nm of torque and I'd be a happy camper!!!!

Gerk,

Can you tell me what size lift you have in your rocket ship and whether the castor correction bushes were necessary for your lift?

Cheers

Chris.

Hi Roachie

Just managed to get back on my seat - you are warming to the fully electronic fangled dangled diesels??? Don't tell me the dinasour has come of age ;-)

While I think the series 3 GU 3.0TD is the ducks nuts, I fully respect the proven reliability of the 4.2 over a number of years. Unfortunately I reckon its only a matter of time before the old 4.2 becomes the new 4.5TD (3.0TD with 2 more cylinders). And even with my one eyed view on these new motors, I cannot but wonder will the "4.5TD" obtain the legendary reliability of the old 4.2.

Cheers mate

Captain

PS. I'm still smiling after beating the 4.5P 80 series. Who would have thought a 4 cylinder 3 litre diesel would ever take the mighty 80 series 6 cylinder 4.5 litre petrol. Just think what a 4.5 diesel could do.

Its not what you drive, but how you drive it!

Captain,

That's what I mean....if the 3 litre jobbie can blow away the 4.5 petrol, I can only try to imagine what a 6 cylinder/4.5litre one with the same technology would be able to do........But it'd have to have PROVEN reliability for me to swap over....PLUS it'd have to still have solid beam axles and not be a Pajero look-alike!! Too much bloody plastic already!!! LOL

Cheers mate.

I agree with yourcomment re body work clapped out befor 400k thats true on the underground vechicles which are clapped out befor 100k, but surface operated vechicles achieve high mileages, driven 24hrs different drivers long trips to different sites (talking about eastern goldfields area)

I have worked in many open pits around the goldfields and I can garantee that the vehicles I have driven are very 2nd hand at only 100k and totally stuffed before 200k If the vehicle is used for transport to sites that may enable it to rack up more ks but the bottom line is that on small sites there are little to no car washing facilitys and vehicles are either left with mud crated from hypersaline water clinging underneath them 24/7 ( a vehicle we took in for service was weighed before and after they cleaned it and it had 60kg mud atached) or they are washed directly with hypersaline water. I stand byn my comment that a vehicle used daily in an open pit will usualy be totally stuffed well before 400k.

Truckster, you counted wrong, it's 20020020202292929u2098347298347923880 times before!

Still good to get an opinion from those who continue to rely on the 3L donk as it becomes more aged!
