I am interested how you came to this result.Hello there mh2017,
Sorry to hear you are having to endure this painful experience with your Y62 and Nissan Australia. But never fear, you will not be out of pocket one cent and the dealership should have also given you a courtesy car with at least as many seats as your Patrol, as they did for us when the repairs took 15 weeks to complete.
Simply call Nissan Australia Customer Service 180003535 and let them know that you have spoken with the ACCC and shan’t be paying anything for these repairs and their tune will quickly change.
Don’t be at all surprised that after you eventually get your Patrol back on the road... the engine will begin to chew through the oil like there is no tomorrow, consequently choking up the catalytic converters, so you are aware.
Buckle up you are in for a long ride...
But seriously, good luck.
Hi there just a question I have a jan 2013 built and did the 110k service today and cut the oil filter and found specs so is the oiler jet from alloy ?G'day folks, I'm starting this thread to discuss, but more importantly, collect data on the premature timing chain failures which are apparent in the early series one aussie Y62 patrols. The issue seems to be limited to the pre March 2013 build vehicles (all with the VK56VD engines), typically with as little as 84K and up to 150K kms on the clock. Interestingly, the American VK56DE engines fitted to the Armada QX56 were plagued by the same issue.
The issue begins with timing chain stretch. As it stretches, the chain guide tensioner pushes the chain out so much it comes into contact with an oiler jet causing engine noise (squealing and rattling) from the front of the engine. The oiler eventually fails and the problem worsens. The engine's cam timing is also affected which can result in poor acceleration.
Video of noise:
Post March 2013, the issue seems to be non-existent ie. engines built after this date do not have the issue as they have been built with revised (beefier) timing chains that do not stretch like the earlier ones.
Cost of repairs (parts only) is approx AU$1300. Add labour and you're looking at nearly AU$6,000. The replacement chain in the repair kit is heavier duty so once repaired it's all happy days.

To drill down further and hopefully segment the affected engines, I've collected a little information, (from FB and alike) to combine build dates with engine numbers. It's only a start so please feel free to add information and comments so that people who have or are contemplating purchasing a 2012 or an early 2013 Series 1 Y62 Patrol have a heads-up of what could be a potential issue. If you have one outside or close to these dates with or without issues, please share the info.
Please provide the Build Date on compliance plate, the last six digits of the engine number and the kms; (Scroll past the pics)

Jan 2013, Engine # 0000997 - Failure - 110,000 kms
Feb 2013, Engine # 0001614 - Good so far
Any update mate?G'day Trevhead,
As of today I have started my Timing chain replacement "Journey". Build number 1014 JAN 2013
I have owned the car for 4 and a bit years and the rattle has been there for sometime. Under load it is especially noticeable. If I fill it up with 91 it sounds like a bag of spanners rattling around. Vehicle is a 2014 STL with 157xxxkm build No 1014.
So far I have spoken to my local dealer - directed straight to Nissan Australia - Directed straight back to my local dealer from Nissan Australia, this is to book it in for a check so they can determine the issue.
Will book in next week for a service and will keep the thread up to date.
Please keep us informed of your progress.I have just started my journey. Car is currently with dealer and discussions started with Nissan. Have owned since new and now clocked up 170,000 kms with perfect service record. I have been waiting for the noise to start, and I had the oil filter dismantled after last service to verify metal floating around. Waiting today for dealer to complete 3 hours of investigation requested by Techline which I agreed to pay -but I also told Nissan I expect them to meet the full costs in the end. The next couple of days will be interesting.
The dealer just called to say they have opened up the engine and found nothing wrong with the timing chain. But they can't explain the noise. They now want to drop the oil and open up the oil filter to check for metal, despite me providing them with the filter from the service at Ontrack 4X4 about 2 months ago which clearly shows metal fragments. Andrew Cassar cut open the filter for me, and was confident the timing chain was stuffed.Please keep us informed of your progress.
Is the dealer open to you dropping by the workshop and having a look while discussing it?The dealer just called to say they have opened up the engine and found nothing wrong with the timing chain.

I'll wait for the next update to see if they have a rational explanation for the noise and the metal fragments. They are aware I have a son who spent 6 years on Nissan's Techline and was one of the first trained on the Y62. If anyone goes in to have a look it will be him.Is the dealer open to you dropping by the workshop and having a look while discussing it?
The timing chain is perfectly ok, it seems the engine has been sucking in lots of outback dust, probably through a badly fitted air filter but hard to pin down. Cylinder 4 is badly pitted. We are getting them to run leak tests and compression tests to check the health of the engine before deciding if repair is an option and in what timeframe.
