I have a 3.0 litre turbo 6 weeks out of warrenty that has just lost compression

Has any one had success with Nissan replacing these motors after the warrenty period

G'Day Johno

I believe that Nissan are replacing engines way out of warranty. You shouldn't have any problems getting it sorted. Search the archives, lots to read.

the issue is with cracked pistons

mine had 3 cracked and 1 broken piston when stripped down

was still drivable at the time just spewing white smoke and is sounded like a little man was inside the engine with a sledgehammer

nissan supply new long motors and reuse your accessories.

due to new oil pressure sensors along with other changes , you also need a 2003 spec ECM and complete engine / ECM wiring loom installed
Nissan are obviously supplying this too.

the new engines have over 25 internal changes to the early series 2 motors. rebuilding the original engine will do little more than buy you extra time

basically if you have a series 3 (clear tail lights) you are safe.

Hi there Johnos,

Can you please give me some more information? I'm collecting any engine problems from the forum and building a database...

I need....
VIN number - last 5 digits.
Engine S/N - All digits

Also, was the vehicle new or second-hand? If it was second-hand, was it ex-government fleet? What brand of oil have you been using and how often did you do an oil and filter change?

THis is what we have at the moment....

Out of 15 vehicles that I know about, 10 of them (70%) have previously been owned by Government fleet companies. Out of those 10, 8 of them (80%) have been owned by Police services.

All of them have suffered a critical failure of the piston, on the leading edge of the injection bowl. All have failed on Piston numbers 1 or 2. The failure is catastrophic and can't be repaired. An over-boost condition is noted in the computer approximately 8 seconds prior to detonation. In 2 incidents, it has lead to a loss of the vehicle's ability to drive, due to a completely stalled cam-shaft, caused by bent valves being jammed.

Out of these 15 vehicles, all have had engines either badly maintained, abused or operated at extreme tempuratures due to low oil. In one case, the engine was being run on Mobil 1!

regardless of how hard the vehicles are used or oil used, this problem is clearly due to an inherent design fault to have motors failing at such low kays...lotsa diesel 4WD motors get abused in various ways but still go for 3-500K kays...

mine did 79,000kms , serviced by nissan and oil changed at 7-8000kms every time without fail.

new long motor supplied

i know of a 140,000km engine being replaced for free and one with lower kms but 6 months out of warrenty being done too.

I tend to agree with Pathfinder - mine was serviced as per Manufacturer recommendations by Nissan dealers. Certainly any engine should be able to handle reasonable demands and some abuse. There are many motors of this size in the 2-3 tonne truck class which give sterling service and work a lot harder than your average fourby.

There is a fault which seems to have been rectified in the GU3, predominantly by changes to the oil gallery system. I have heard of many more than 15 - One govt dept in NW NSW had 13 at last count (not the police)

In other comments here I referred to Government & Police vehicles - I meant that they click up the K's faster and hence are amongst the first to be seen with problems. The GU2 was released May 2000 and the sump recall was in December 2000. Obviously there were some high milers that had failed by then.

The overboost noted could be something to do with blowback through the hole - mine went at 110kph on the freeway and it felt like the vehicle wanted to bolt for a while. The blow back would happen because the hole in the piston would be forcing air from the sump in on the downstroke for intake with the intake valves open. This could well overide the boost from the turbo. The initial symptom was a rattle like pinking and then the attempted bolt away. The motor continued to run albeit as Roly has described.

I would appreciate any comments regarding high mileage GU3's - there should be some around the 150k mark by now.

A guy by the name of Roly had his whole motor replaced under warrenty by Nissan.
Ask this question on overlander.com and you will probably get him to answer.
Apparently common on early 3.0 motors to melt pistons amoungst other things.

the johnos,

Got mine replaced at 140k's. About 3 weeks over time + 40k's over the 100k warranty.

Problem was No 2 holed. The motor was not stripped - just sent back to Nissan factory. I seemed to be lucky - no oil sprayed everywhere. It would not be unexpected to see Police or Govt vehicles at the fore as they typically run higher mileages.

Service history is one owner since new. Services every 5000k's for first 20k's when the sump upgrade was done. Lubricants were Nissan. After the sump upgrade I went to 10k'service intervals (oil+ filter). I have also had and used a turbo timer since new.

My useage is predominantly freeway/country 90% and about town 10%.

I am interested in the run people are getting from the GU 3's.

Any chance of letting us know the milage and year model of your vehicle.?
Sorry to hear of your problem. I have a feeling Nissan will look after you though, especially if you have been having Nissan services...

thats the entire reason to have your service at nissan and not at ultratune dodgy mart


it goes a long way when you are 6 weeks out of warrenty.

look at my truck, nissan gave me a new engine even with all the mods / changes as they know the service history of the motor.

mine went in april and was a test case , it took 6 weeks to get the motor approved and delivered from japan.

Dont have to take it to dealer for servicing to get warranty
Mazda replaced a truck motor at 80000kms (60000kms out of warranty)
and I think from memory about a year out of the 12 month warranty at the time.
The owners had never had it serviced by us (the only local Mazda dealer at the time)that was along time ago though.
Also suspect it was the owner not changing the oil that caused the problem.

warrenty is warrenty, goodwill is different

in this case, nissan will supply a new engine under goodwill

to the letter of the law, the engine/vehicle is out of warrenty ( 3 years 100,000kms) and nissan is within it's legal rights to tell the owner that the bill for a new long motor to be fitted is around $17,000.

Thanks fgor all the replies & it looks like Nissan are going to replace the motor with a short motor.

Some aothe details you have all asked
Model is june 2000
60,000 kms on the clock
Seviced by Ryde Nissan NSW ft each 10,000 kms until 30,000
Traction 4 Artarmon NSW service 40 & 50,000kms [MTA member]
I also changed the oil & oil filter at every 5,000 kms with Castrol RX Super 15W/40 [As recommended by Castrol themselves as it matches the oils specified by Nissan]
It appears to be 1 ot 2 pots have had the rings break up

As i have had or been involved with diesel motors in Trucks, agricutural machinery & earthmoving gear for the last 50 odd years I have always been very particular about service & maintenance with this being the first diesel motor that I have owned & looked after which has gone on me in this period
