3.0lt GU Patrols - Grenade Facts

Hello All,
I'm fairly new on the forum but I managed to get my hand on the Nissan Patrol Reference Document.. and I've read it twice! I'll soon be getting (about a month to go) a 2008 GL 3lt diesel patrol wagon. It's done 100k and the previous owner has just done a major service on it, changing the tensioner on the belts (+ belts), a steering damper, and an electric window, rear shocks and a bunch of other small odds and ends and filters and oils. What I seemed to understand from the reference doc is that newer Patrols have had issues ironed out that perhaps plagues older models and are the main points of discussion in than reference doc.

So my feeling is that some of the supposed "fixes" that are suggested in the reference doc may be unnecessary or out of date for my 2008 model, and besides fitting a snorkel and an oil catch-can there's not really much else I should be doing (at this stage). Just a note I'll be doing moderate 4x4ing, a lot of city driving, little or no towing and moderate highway driving. Any other experiences with 2008 model Patrols that I should know about? And which mods are really necessary/recommended.

Thanks

2008 is a Common rail Diesel and does not have grenade issues. Catchj can is always a good idea on any diesel.

A friend of mine in the RAA told me that the early Di's (2000-2002) did have the hand grenade issue but it got better with each revision. By 2006 the Di's where much more reliable. Since the CRD's where introduced the failure rate of the 3.0 litre is the same as for other manufacturers. This is based on call outs to tow cars and workshop info from associated RAA approved repairers etc.
He even mentioned that if you call the RAA and ask them for advise on cars they do not suggest you buy a Di for towing but CRD's are alright. I haven't called to verify this though.

I have just read this entire thread and found it very interesting to say the lest.

One point I'd like to bring up is.... if this was an inherent problem, why have Nissan not done a recall on the motor to address the issues, or do Nissan totally reject that there is a fault with said motors.

Are the motors a Renault motor as ive been told this

Not all motors blow up so Nissan can deny its a problem. No one really knows the exact percentage of grenades. While you hear most of the horror stories, you don't always hear of the ones doing big km's without problems as a lot of owners don't get on the web to research their cars if there are no problems. The danger is that if you read too much you start worrying constantly. I am not sure if ignorance is bliss in this situation.

These ZD30s are not Renault motors, if they were they'd be fixed long time ago! In any case no European engineer (except Bosch cretins) would put his name to such abomination. It is standard Japanese engineering afterthoughts!

Nissan just follows established standards of Japanese culture; "never admit failure to risk loosing your face" aka shame!

When you look at any Japanese manufacturers the tendency is to deny/lie/avoid/obfuscate anything but admit fail until they're cornered like the filthy rats and exposed! Toyota, Mitsubishi, Takata, Sony, Panasonic, Nintendo ..... the list is endless. Heck, look at the successive conservative Japanese governments, to this day they will not admit to the crimes committed in WW2. No apologies, no souls searching, no public admissions like Germans for example.

Regards

I thought I'd ask the question about it being Renault, I either read it or heard someone say it , just wanted to be sure

I read somewhere that the ZD30 is the first diesel engine that Nissan has designed. All the other diesels (TD42 etc) where designed by UD which was part of Nissan. When they had their financial difficulties in the late 90's the truck division was sold off and Nissan went to Renault. That's when they designed the engine and why Renault gets the blame. I think the ZD30 is also used by Renault in some of their trucks/vans.

The YD25 is Nissans second effort at diesel and I think is much better. The 3.0 litre V6 is Renault through and through. That's why they where only installed in the Navara which is also built in Spain(?).

Thanks Rock Trol for shedding some light on it for me... cheers

sorry, i got a quick question - having looked around for a bit i bought a 2002 pre crd engine and now a 2006 model has come up. which yer did they go to crd?

around mid 2007 onwards.....

yep. thought so. thanks for the quick bit of advice... faster than Mr Google

Hey guys interesting and useful thread but i am in the position to get a patrol round the 02-04 vintage im looking at the 3.0ltr but getting concerened with all the conflicted reviews. What if any differences are there between the 02-04 year models? And obviously the 4.2ltr is the favoured heart in the troll but does that stand for the whole range right back to 99? Are the older 4.2's all good?
thanks in advance

Interesting read and some good points made. I am in the market for a Patrol with a budget of about $10000. This means I am looking at a 1999 - 2003 model. I was leaning towards a 2.8l due to the grenade reputation. I have seen a 2001 3.0 with 450000km on it so cant all be bad.

There are many out there mate with very high KMs . But then again , I believe all the grenade candidate ones have already popped. Although even the new CRDs are going bang.
You can always score a 3L and the NADs it and hope for the best.

hey guys. just after a bit of advice. im looking at a 03 navara d22 zd30 with 400,000 on the clock, its $4000, is it safe to say that if it was going to grinade it would of done it by now, secondly how many kms are people getting out of a zd30? after all they arent a td42.

thanks. James

No, it would appear to have lasted so far but grenades can happen at any time.

It varies, I have 230,000ish on mine and another club member over here has 300,000ish with no issues. Plenty of peeps have had failures below that number of ks even on td42s.
A Navara with 400,000 on the clock will have some wear and tear, not only in the motor. It depends on the individual vehicle. Maybe you should try a Navara forum, I think there is one.

Thanks mate. Been a member for ages so thought I'd try the clowns I know lol. Thanks for or help

Hey guys new here my intro in the intro forum, but I own a 2010 GU Patrol ZD30CRD and I stand by my car and defend when I can. A lot of people who debate about these engines really​ don't know much about them just state the same negative issues over and over again without knowing what is really going on. I have owned my truck for 3 years going on 4 and have not had any "common" 3ltr issues as people state. For a good 2.5 years I didn't have the EGR blocked and ran a 2.5" exhaust, I didn't want 3" as a lot of people experience boost spikes. It has been through heaps with me, had good times and bad times. At one stage the engine bay caught on fire from the turbo getting hot! And when it was hot I mean hot, fire was sparked from the fabric on the back of the engine bay, we were able too put it out haha. This all happened on Bribie Island beach and I had a bad spilt on my dump pipe so not only did I have a bad leak I also had a lot of the heat escaping and not getting out the back. But she's still kicking and going better than ever, it has since had EGR blocked but that's about it. These engines are strong, they produce power and can be modded for more power. You can't say bad things about a motor unless you have actually owned one, as they say you can't judge a book by it's cover and the same goes here you can't judge a motor just by what other people have said! Overall I'm very happy with my truck!

Does anyone know a mechanic in Adelaide that can do the nads mods?

Thinking about getting a 2003 ST 3L but reading a lot about the "grenade" issue. Will have a read through this forum but if anyone has any sage advice that would be very welcome :) Cheers. Ben

Its no denying that this is a real issue. There is plenty still going around with 300plus thou on the clock and not using a drop of oil.

Try and buy something that has already been rebuilt, or as low as possible k's on it. Even a rebuild is no guarantee you are safe. I bought mine with a 40k old motor, 50ísh though later the IP died. I ended up doing a TD swap, removed the head on the ZD and number 4 piston was cracked and ready to go. I have said to other people if you buy a 3Ltr, expect it to drop the pin, if it doesn't then great! They are a good little zippy motor. Good if you will be driving it as a daily and your living in the burbs with traffic. You can get them going pretty good to with some mods.
