Do late model Nissan 3.0 CRD's go bang?

Thats enlightning!....Hahahahaha.!



Cheers Axle.

and..............?

Well that was handy as a chocolate teacup. So what's the background to it blue one?

Was that gleaming pearl of wisdom direct from your colononic irrigators green grocer's aunty's hairdressers cousin best mate's plumber's neighbour, or was it actually yours that KB'd?

Not in the mood tonight. Please keep the responses useful good forumites or don't bother.

I'm waiting to here the story also, probably about a mate of a mate blah blah blah.

How's yours going Daza? Happy with it?

Did you go the auto?

We haven't had any problems with it so far, it's still under warranty, and if we don't trade it for a newer model, we will get the extended warranty, it tows the van ok, it's good driving on the beach, we don't flog the guts out of it, and we get it serviced every 5000ks, we have a good relationship with Gold Coast Nissan and their service people, I have discussed the issues re the blown 3ltr motors, and the info was that it has been fixed re 2005 onwards, this problem shouldn't have happened in the past, the amount of 3ltr Nissans that have developed problems whether it is through lack of proper care or what ever, is insignificant to the thousands that have given their owners good reliable trouble free motoring.

My concern would be that you couldnt trust a single word out of nissan's mouth, including what they tell there dealers, considering the way they have treated there customers for years, and there have been many examples on this site alone.
My other concern is that they probably havent stood the test of time yet to see if they have fixed the problems, somehow i doubt it.

You could be right Pesty, only time will tell,

As far as trusting Nissan, I agree a lot of people have been let down, from what I have read, but again I dont know how they approached the situation with their complaints,

I have been dealing with the same Nissan Dealership for several years, and they know that I'm a straight shooter and I expect the same from them, only one time did I cross swords with the service manager, and he promptly found out not to stuff around with me, it took only one phone call to the Principal of the dealership and it was sorted out.

I have lost count of how many 4wd's we have had over the years all makes ect, from various dealerships and we have had very little trouble, the funny thing is I remember the most expensive 4wd we purchased was the one that gave us the most trouble, it was a new 90 model Range Rover, in those days I used to lease them, and it cost us a fortune in down time, it was allways in the workshop.

I agree Pesty - Nissan took a long time to even acknowledge the problem in the first place. Wait until the CRD's get the same sort of mileage and see what happens... assuming it's the same engine of course.

On the other hand, the CRD engine could be so different that all the problem bits are no longer part of the engine, in which case there should be no reason to suspect it would be any more prone to explode than any other 3.0L CRD variable-vane turbo on the market (eg. IsuzuUte, Prados with D4-D engine, etc.)

DAZA, is it still the ZD30 engine? And do you mind telling us what sort of mileage you're up to in yours?

Yes ZD30 CRD

Around 11to12 ltrs /100ks,

Towing 2300kgs around 17/100ks,

Very low ks 12000ks on the clock,

Not even run in yet, shopping trolley for the Cook,

I drive it when towing van,

Daza, if the dealer told you that the problem was fixed in 2005, would they be good enough to tell you what caused the grief and what has been changed to eliminate the problem?
I am sure a lot of people would like to know the exact cause.

I'll send them an Email, requesting the info, the service manager is only to pleased to assist, when I get a reply I,ll put it on the forum.

Daza, I am sure it would be in Nissans interest to let it be known that they have isolated the problem and eliminated it.

Maybe there won't be as many 3.0 owners on sleeping tablets if they know the problem is fixed.

Dave

Hmmmmmmmm.........I guess by your name they are underground rigs. Always a good test of a vehicle's toughness and low range longevity. Not a good hit miss ratio is it.

For the same reason (OS&H / airbags) a lot of mines in WA have experimented with Luxes and even Rodeo's with varying degrees of success.

I'll be interested to see what further reports come through tomorrow. Were they definitely the new CRD 4 cyl Patrols you are referring to?

Toyota management must be on crack not to have air bagged the latest 70 series. Imagine a bare bones 4 door auto TD V8 Landcruiser 70 with factory difflocks.

No-one builds what I want to buy.

they are airbagged now arent they?

"a lot of mines in WA have experimented with Luxes "

- they take a Lexus underground ????

V8,
the vehicles I refer to are exploration units that are used on the highway, this is the reason for the airbags. The reason for the Patrols is exploration is a separate division so they buy what they want.

The vehicles are about 18 mths old.

I hope Nissan repower their patrols shortly as they are doing a lot of damage to their reputation.

Don't think I am a stick in the mud cruiser man either as they also have their faults.

They would still be getting a hard time though but to total 2 engines is definitely different.

We have Hiluxes as well for around the surface but they don't do any real work.

"they take a Lexus underground ????"

Luxes not Lexus!

Registered last night and the WA one as well.

Cheers.

Much appreciated.

It would seen the old ZD30 MAF, VVT and EGR valve issues have not been rectified with the CRD model then if an '08 went boom.

Yes, I came across a bloke last year with a 4 month old 08 model. It konked out up a hill towing a van and was no go after that. Fella couldn't tell me exactly what went wrong but Nissan fixed the fault quick smart. Owner was bitterly disappointed with his choice of vehicle.

BUT...there seems to be thousands of 3lts' out there with no issues. Their popularity being that they are significantly cheaper than buying another brand.

Towing heavy vans with 3litre powered vehicles is asking for trouble, in my opinion.

Steve, I wondered the same as you about a small engine pushing 3T around, but then someone compared them to the coaches we drive...

16T (loaded) coach with 9L TD engine
26T (loaded) coach with 12L TD engine
or
3T (loaded) Patrol with 3L TD engine

Now which one looks like a small engine pushing a big load around? And let's not forget these coaches are expected to do at least 1,000,000km before an engine rebuild...

I suspect some of the difference is in the way those bigger engines operate. They are built very robustly and not built to rev very high. Plus they have about three times as many gears before they get to top.

Actually, the later Scanias I drive are 7 speed and the Mercs are only 6 speed. The earlier Scanias had 8 gears in a split gearbox.

I think you'll also find with those big engines its all to do with torque production - how much, where in the RPM range it is delivered etc

Fair point. In the back of my mind I was thinking Road Ranger and I guess older coaches with around 12 speed etc.

Agree, there are some significant differences. I just wanted to point out that the 3.0L engine in a 3T vehicle may not be a problem in itself. Perhaps it becomes a problem when the consumer wants a 3T vehicle that will keep up with the zippy little hatches...

The Golden rule with diesels is (the bigger they are the more reliable and long lasting) The variable vane turbo that leads to overboosting seems to be the root of the trouble.
Thank god I have a reliable v6 petrol lol
Cheers Pete

The D4-D Prado engine has a variable-vane turbo in it, as does the IsuzuUte (both of them are 3.0L 4cyl too!), and they're just two that I know of - who knows how many more out there?! I guess it will be interesting to wait and see how they go in the longer term...

I'm not convinced about cubic capacity and life expectancy of engines being directly related. If the power and torque are generated and delivered to a drive train that is correctly geared, and oil circulation is adequate and heat dissipation is sufficient, then a small engine should last forever.

It comes down to design and obviously, if it is true that the 3.0 L Nissan motors are still blowing up, then something is very wrong with the design.

My Disco 3 has just a 2.7 L engine, yet it is a heavier vehicle than the Nissan. The engine generates more power and torque than the Nissan motor and can pull heavy loads without problems. I've scoured the Internet and cannot find a single example of one of these engines failing.

Last year I worked at a Land Rover Dealer for 6 months and there were no technical bulletins concerning engine failure. They just don't break.

So if the French can do it (the TDV6 is a Peugeot motor), why can't Nissan? Toyota have many times more 3.0 Litre engines in Prados and Lux's than Nissan have in the marketplace, yet they seem to have it right.

Nah, in this modern age of computer aided design and minimum tolerance engineering, cubes = longevity ain't necessarily so, but Nissan do have a problem IF they are still failing.

Cheers

The golden rule is that you can only pull a certain amount of power from an engine before it will become les reliable. The bigger the cubes, the more power b ut every engine has its limit.

"So if the French can do it (the TDV6 is a Peugeot motor), why can't Nissan? Toyota have many times more 3.0 Litre engines in Prados and Lux's than Nissan have in the marketplace, yet they seem to have it right. "

The current crop of diesel engines in Nissan vehicles are French made.....Renault. My D40 has a 2.5 ltr diesel made by Renault that produces 128 kW and 403 Nm torque....smaller and belts out more than the 3ltr. Gotta say that I hope the design is right and the con rods/pistons and block are strong as at 100kph on the highway these engines are running 28.7psi MAP - that is approx 14psi of boost.
