Patrol 3.0 Turbo Diesel Engine Rebuild

Not usually any need to remove the engine for gearbox repairs.

You can remove the box without removing the engine.

Thanks for the input but I think it has been more than a gearbox as some evidence you can see is sealant or gasket goo oozing out from between engine components at the top end. Not the sort of thing you would see from a factory built and installed engine.

I hope I get the same mileage as you and more without any issues.

Thanks,

Bob

Robins wonderful light weight 4.8 blew up with less than 2000klms on it...

I'll give this some thought but as it was owned by a Christian Outreach Centre it may be difficult to find someone who remembers the vehicle after all these years.

Thanks

Bob

There is your problem straight away. It has been owned by blaphemous god-botherers who were struck by lightning on the way to a Jambouree. It probably took 6 months to find them and then it just drove back 200 kms to the church.The gaskets would have melted when the lightning hit and caused them to ooze a bit of sealant.

Seriously though 6 months off the road could be either a rebuild or a quiet t ime for the church. With budgeting etc... they may have actually just not used the vehicle.

I hope that this is not the case with mine and I suspect not as I crawled over and under the vehicle and it all looked original and genuine but you never know. You are right Nissan would know but how willing will they be to share the info especially if it is not good news.

I will keep asking.

Thanks,

Bob

Bob,

I should have pointed out, I do not wish this upon anyone so sorry if that was the way it was taken.
Any warranty work you need done on the car (if it's stilll in warranty) will not be done if the car has been written off so Nissan should be forthcoming with this info in my opinion. Unless it was one of their dealers that sold it, then it may be hard to get the info.

Happy hunting where the 6mths got to.

As the vehicle was owned by a church organisation and it was still under new car warranty then I would expect any work, minor or major would have been done under warranty and Nissan would have to approve the work before it is completed. Therefore there should be some record on what was done. There is no doubt that some serious work has been done but exactly what is unknown. I purchased it from a Nissan Dealer in Sydney and I commented on the gap in its life at the time of buying it and they could not offer any explanation. There is no record in the papers I have of the vehicle being sold or traded and as a church organisation owned it I think it is unlikely it just sat there for 6 months. It has now travelled 87000ks and is still going strong.

Bob

Can we write them a ticket!

I love how people keep saying 'unconfirmed reports'...

it's been done to death. There are a number of members here that have blown their 3.0l engine. Do a search and you will find who these people are.

Leroy

Phil, it sounds like your 3.0 may well be another statistic, going by your previous post.

Hello Off-Track

It may well be, keep tuned to this station!

One thing is for certain, my ZD30 is going well today, and I am going to keep on 4wding without taking heaps of valium because I am worried that my No.1 piston may get a hole in it.

regards
Phil

Phil,

These forums have a life of their own, I hadn't logged onto my PC for few days and was surprised to see this still going. I agree with your sentiments and this was why in the original post I requested that patrol bashers stay away as I am not interested in their comments which generally are ill informed. I suggest that anyone who owns a 3.0 patrol and are concerned with the engine, speak to a genuine diesel expert and get real advice from them. I did this and you learn a lot. They are the ones who discovered some serious work had been done on my rig (answers still outstanding)
I have recently had some mods completed ( intercooler fan - standard setup is inefficient: EGR valve mods - standard setup pumps super hot air directly into 3 & 4 piston and in right conditions contributes to these piston burning holes ) These are only some considerations and the complete engine maintenance needs to be addressed, correct oil and frequent changes, regular checks on MAF sensor, use only genuine paper air filter elements and not after market substitutes.

I have found by speaking to the experts face to face you will get better information than relying on only forum feedback as there is too much emotion and then you have to sort through the rubbish to get any useful info.

Don't get me wrong I believe this form is great when used in the right manner unfortunately far too often a post is highjacked by others with their own agendas.

As for my patrol, will it have problems? who knows but theres no point worrying about it, look after it use it for its intended purpose and enjoy it. My patrol is going well and I think slightly better after the recent mods.

Good luck with yours, and again to you and everyone else who constructively added to this post thanks, to the distractors consider yourself ignored.

Regards

Bob.

We have just had to transport our patrol 3.0lt (2001) back from nth QLd after blowing a hole in No 3 piston (126000k's) Nissan are doing a re-build.
Where's the best place to find more info on this.
How often do you think this happing
Look foreward to your comments
Regards

>>> I am amazed about how few actual owners of a Nissan Patrol ZD30 actually claim their vehicle's engine blew.

B & M,

Sorry to hear about your patrol. I hope Nissan do the right thing for you. As for how often does this happen, that is very difficult to determine as you hear of very few direct occurrances like yours, mostly its a friend of a friend etc. That's not to deny it happens as you have experienced but the actual number is not known and Nissan certainly will not tell. Where to find out more is as difficult find out. If you do searches in this forum you will find a lot of information but you will find even more crap on the matter. I have been reading this forum for the past two years and I have been worried, confused, annoyed and lots more as I read the information available. Simply said it is difficult to work out the truth from the crap. Read the info but take care in what you believe and get indepentant advice from experts (not Nissan) to help understand the issues. I have just recently had some mods done as you may have read as above and this was done after consulting with diesel experts over some time before I decided what to do. I am happy with my decisions and hopefully I will avoid what has happened to your 4WD. Despite what you may read I don't believe there is one simple cause to the engine failures as some people believe. It is a combination of issues which combined cause the failure and in the vast majority of patrols this never occurs. Unfortunately in some all the wrong things happen and the engine fails. I do noy lay any claim to knowing exactly what all the factors are but a brief summary of some of the things I have learned are as follows:-

**regular servicing and oil changes every 5000k
**Regular changes of oil filter
** Regular change of air filter - use only original paper type.
**MAF sensor checked regularly and replaced if faulty
**Inefficient airflow through intercooler - fit fan or take other steps to improve air flow. Recommended not to have bonnet protector as this deflects air flow over air scoop to intercooler.
**EGR valve (this causes a lot of controversy) block system off to prevent exhaust gases re-entering engine I won't elaborate here but do a search in the forum and you will find a recent but long discussion on the subject which I believe supports this action.

I know a lot of this is too late for your current situation however after you have the patrol repaired, it you decide to keep it, you may wish to consider these matters.

Best of luck

Bob
A Proud Patrol Owner
