3ltr patrol problems

Yep they are just too risky........all the stories here, a family members series 3 went POP couple of weeks ago.

You could not give me one.

Yes lots have had no probs, BUT lots have nearly been sent BROKE because of them, its a real shame as the are as tough as they come in every other dept!

Your suggesting they are not that bad!!!

So you must be a brave man to now suggesting they are that good.

Where did i say they were that good?

My 2003 ZD30 blew last month at 182000km. This was WITH ALL the mods, post 2003. Go figure.

I'm still trying to GET OVER IT sport.

Sorry to hear mate, u got me there.

I still find it hard to believe that theyre having that many problems with them, over at patrol4x4 the later ones dont seem to be causing to much dramas

Anyway, now you can go and get urself another popular brand of 4by and never have another problem, sport.

"My 2003 ZD30 blew last month at 182000km. This was WITH ALL the mods, post 2003. Go figure."

I have to ask, what mods did you have done and how late in the engines life did you do them?? It may help us to decide what’s worth doing or not.

Along with the mods that Nissan made in production for 2003 I had a boost gauge that gave me no warning of the pending disaster, it was showing around 18-20 boost, while highish it was not around 35 that some people claim they get.

I feel that what Nissan have done with the production mods is delay the problem and that is now appearing in post 2002 vehicles at much higher Kms than the pre 2002 at around 85000km.

I have spoken to another 2003 owner this week that had his blow up at around 168000km and like mine was after the production modifications done to the SrIII in late 2002.

JMHO but I think the problem is only now showing up in post 2002 cars as they get toward 200000km.

See thread 58452 (don't try the following at home) as to how i'm going to fix it.

Hi Colin,

I think you misunderstood Wayne’s statement regarding mods to the ZD30 Patrol, or I misunderstood your statement “This was WITH ALL the mods”.

I’ll agree that Nissan haven’t really fixed the problem and I doubt that they could and still have the Di version meet Euro3 emission standards. All they did was increase the oil capacity, which as you stated gave the engine a longer life, but still many have failed.
From October 02 there were no significant changes in part numbers until late 04 when the GUIV was released and I think from memory it was only the MAF and something with the cylinder head and pistons that were changed. Plenty of GUIV’s have failed also, but they should live longer also.

As far as mods go, fitting a boost gauge is beneficial if your turbo over boosts, but won’t help you if it over fuels. An EGT gauge would have helped you there, but Wayne was referring to the mods that many people do to improve the life span of their ZD30 Patrols. These include bypassing the ECU boost control and fitting a manual boost controller. Lowering your boost and fitting a free flowing exhaust without a cat and blocking the EGR. Also fitting a crankcase oil catch can, intercooler fan and electric fuel pump will go a long way to improving the life of a ZD30 as long as it’s done early in the engines life.

These are “all the mods” that many have done to try and improve the life span of their ZD30 Patrols, and so far I don’t know of any of them that have failed. Personally I have gone much further than this with mine and even run diagnostic software to monitor the engines sensors in an attempt to pre-empt any pending problems, but time will tell.
I don’t have too much faith in them, but they would be a great engine if they weren’t so problematic.

Good luck with the LC transplant.

So you didnt do ALL THE MODS after all, nissans production mods? A boost gauge, christ, wot a mod!

Cheers PAL, Wayne.

LMAO !

Having said that I have a 3-0 patrol, its on its second engine which has done about 30,000kms, and it performs well now. For how long I dont know. The first engine did 195,000 but there was always something happening and not quite right. I now only do about 10,000 max per year so I reckon I've got about 20 years life left in it yet. I could trade it but why. I'd probably get a cup of coffee for it while waiting for the plates to be fitted to a new thing.
Anyway I towed today, a 4-3 metre boat and it did it effortlessly but that is a pretty light load for it. I'll keep mine but I would advise people not to go through the same "pain" as I have.
