Howdy,

Fairly new to this scene, really enjoying the read!

I've got a fairly detailed question (in my eyes anyway!). In the market for a new GU 4.2 Turbo Patrol. Currently own a 90 4.2 diesel GQ aftermarket turbo 4inch kit with all the bells with only 180k's on it. What is everyone's experience with the 4.2 Turbo Diesel re: drivetrain etc and if I was to have 4 inch kit, and 33's fitted to it, would it cancel my warranty. Further can you fit the upgrade computer and keep warranty plus ie. powerup from Brisbane Turbo and exhaust and keep warranty or would that void it? Would it be worth while keeping the GQ if the experience with GU 4.2 TD isn't that good? Anyones input is valued.

Cheers

Trol

Hi There, I dont know about the rest of the questions but 4.2 tdi doesnt have a computer as such, the only thing controlled is the EGR valve, the rest is totally mechanical . The way to go for reliability !!!!! Cheers Michael (4.2TDI owner)

Trol,
As far as I know, a manufacturer has to be able to demonstrate that the modifications you've done to the vehicle have led to the fault occuring. So, for example, if you had the power-up modifications done and then blew a hole in a piston or the fuel pump went "physssssst", then they could argue that you helped cause the problem.
However, if you had all that stuff done and then the electric window mechanism went on holiday, they couldn't argue you'd caused that by what you'd done.
Just my opinion.....and then it starts to get all mirky.....like what happens if you start to over-heat?.......or the bigger tyres could be said to contribute to premature wear in the steering and brake department etc.
I have a 2000 4.2 t/d and have it fairly modified too. The only warranty work I needed to have done was at Nissan's own recommendation and that was to replace 5th gear before it let go; but they've fixed that on the newer models so I believe.
Great truck, you won't regret buying one.....obviously you've had a good run out of the GQ and it is barely run in. You could certainly do worse than to hang on to it if it's going okay.
Cheers,
Roachie

Hi Roachie,

Thanks for that! How many K's had you done before 5th gear let go? Is this a problem in the 4.2 TDI?

I guess that mods are something I could chat to Nissan about and get them to put their confirmation of a mod in writing...

Cheers

Trol.

Trol,
My 5th gear hadn't actually let go. I was lucky in a way. This is what happened.....I ususally do all my own services. When I moved over to SA from NSW in late 2002, I couldn't bring all my gear (ramps etc) ; so I booked the Patrol into the Nissan place to have a oil change done. When I went to pick it up, the service manager asked whether I'd had any trouble with 5th gear. They checked the gearbox oil level as part of their service proceedure and found it to be coffee coloured, which he said was a sign the no.5 cog was on it's way out. He actually offered to have it done under warranty, with about 85,000klm on the clock. I've now done over 116,000klm and no worries.
As I said before, they've known about this problem for a few years and the Patrols made over the last few years have had the stronger cog in them from new, so the 4.2 T/Di won't have that problem.
Cheers,
Roachie

Roachie,
Did nissan tell you to change 5th gear before it let go? my dealer up north told me they will NOT replace 5th gear until it lets go. I have a 2001 4.2 patrol and have been keen to get it replacement before its destroys it self. I might have to have another word with my Nissan friends..hehe

No, they didn't "tell" me to get it changed...........they "offered" to change it for me under warranty....how could I refuse?
He reckoned it would be about $3,500- to get it done outside warranty. He tried to get me to take out an extended warranty for about $800-, but being a bit of a gambler, I declined.
They had the truck for 2 days and showed me the parts they took out. They replaced 5th cog as well as the main shaft. There was a helluva lot of slop between the two. It is actually the inside spline on the 5th gear that was giving up the ghost, not the outer large teeth. I think Nissan had tried to save a few dollars by skimping on the length of the spline, which had put too much stress on the parts.
Cheers,
Roachie

Roachie,
Could you let me know the name of the dealer that replaced you 5th gear as I have asked here in Perth and they told me Nissan will only do it when the box goes bang.
I have done almost 80 000 and am on my way up north soon so am a bit concerned it may die on me.I will have a go at Nissan if I can get confirmation from the people who did yours. PM we if you like.
Thanks. Ray

Ray,
The local dealer here is Gunnings Motors, 5 Taylor St, KADINA, SA, 5554
Phone: 08 8821 1022
I can't recall the name of the service manager, but I'm sure it's still the same bloke there now who organised my repair.
Good luck mate,
Cheers

Get it in writing from Nissan, what effect (if any) it will have on your warranty ..... not the stealer.

Pathfinder,

Is that from experience? I have had a 25k offer for trade up on GU. Really appreciate it.

Cheers

if you can get $25K changeover deal, then probably worth considering. However, I would have thought your current GQ with aftermarket turbo would make more power than factory TD, so why change? What's wrong with your current car/truck?

Yes, it does, puts out 110kw at the wheels with only 12psi, substantially more than the GU. However have come into some money, and feel that an upgrade whilst the GQ still has 'young legs' may be more commercially viable for me. Nothing wrong at all with the Patrol GQ, no rust, it runs like a dream and knocks most TD 4WD's off the line pushing the big 33 MTR's. Love driving it but would also would like to drive a new truck with the mods with zero k's. I must admit, I've read a couple of previous forums on the TDI GU and it has put me off a little.
