Thread: Another Nissan bites the dust

I have no updates so far on the 3.0L Patrool.
When I do will try and even get some pics.
I do know he is selling it now as he does not trust it anymore.
He paid $55k for it, another $12K at ARB and now after all this probably another $15k.
He could have boughta D3 at the time and forever laughed.
He is a good bloke and sure as hell did not need this issue.

Keep you posted.
Jarred Nissan is doing the work and I will look into doing a current affair story on it, I see how I go.

Same deal I knew of someone with an 05ish model with 130k always serviced/maintained. 15k for new motor and the best nissan came up with was we'll contribute 2k towards it. Pretty ordinary I reckon!!!. I also knew of a fella that was that peived off with his trol sold his 07 model with blown motor for $3500,Unfortunately I found this out after he'd sold it. How can Nissan not recognise this????

The head is off and a hole in no 3 piston has been found.
My mate is sending me a picture.

They are writing and emailing Nissan as I type.
Jarred Nissan the only Nissan dealer in SA that would touch it does not have much hope for any contribution or warranty claim though.

He is looking into joining a group of people mainly grey nomads who bought them as their last vehicle to tow their mobile coffins(Caravans) around who are putting together a class action.
He has finally worked out that if he puts 3L nissan in Google search very little good comes of it.
What is really funny is that he is now asking me for info on my Disco and what they are really like.

Its taken me 20 years to get him to see the light.
Fingers crossed he will get his fixed, sold and I get him into something with soul, charactor and the ability to do more than 50k km's before melt down.

The ZD30 motor is known for this.

Just to clarify: IT ISN'T THE MOTOR'S FAULT.

It's caused by a combination of MAF, ECU, over-fuelling and turbo boost.

Take ANY turbo diesel with an ECU, make the MAF think it's flowing more air than is actually moving, add a turbo boost increase to the mix and maybe a slight ECU tweak, and you have a disaster.

Most, if not ALL, of the ZD30 grenade sessions are due to too much diesel being injected, a high boost condition, and excessive EGTs. The result is holes in pistons.

I've heard the same thing about Toyota KZ-TE motors, D4-Ds, you name it.

Your mate will do well by fitting an Exhaust Gas Temp probe and gauge, but actually preferably an EMS unit of some type, that measures various sensors and temps around the motor.

I've seen Nissan Patrols with the ZD30TTi motor do an entire Africa trip with just regular servicing: BECAUSE THE ENGINE WAS IN STOCK TUNE and there was a monitoring system that checked and alarmed.

Where the manufacturers are negligent, is that such a unit isn't fitted as standard, maybe as part of the on-board computer system.


By the way.....
Ask the Jeep Grand Cherokee guys how long the 3.1 diesel motor lasts......

I think there's quite a few people who would get in on that class action and I bet Nissan will wish they had done something at the time.

Correct. The engine is actually a nice bit of design, it is the excessive EGT's etc that kill it. I have seen 800C+ (upstream) under medium load conditions in one of these vehicles, goodness knows how hot it'll get towing a 25ft van at 90km/h

Incorrect fuel and boost management is the issue here, I guess IF they had released these engines with sensible fuelling etc, they wouldn't have had anywhere near the pwer etc that they have, IE they wouldn't have sold too many

So would the diesel chips that the aftermarket suppliers make it better or worse because I know people who have those fitted to make them go harder.

Almost definately make matters worse Matt. Unless they fit a bigger Intercooler and exhaust etc it is a pretty big bet the EGT's will be higher, believe me from what I have seen with a standard vehicle, 1000C isn't unachievable with a chip when towing/ working hard, and you KNOW what that does to turbine mettalurgy and aluminium components?????

ALL these vehicles should have a pyro fitted, standard OR modded. You'd be horrified to see how hot they can get.
