Landcruiser 300 engine failures
« on: Feb 25, 2025, 01:47:14 PM »
As expected, massive issues with the new landcruiser. Its a hot V engine

pistons overheat and seize on the bore. 0-20w oil, steel pistons blamed. Oh what a feeling!

Yeah, John called it ages ago... I've seen a few gripes from people who ask a lot of them... Wild Touring springs to mind.

If you buy the first series of something new, you are the Beta tester.  That's the way these things work.  I recall a John Cadogan video where he gave a very strong recommendation not to buy the new 300 for a while, to let them sort out the issues that will arise.

What I wonder is why he has this engine (and apparently 2 more) in his shop.  Normally, a new vehicle, under warranty, with an engine failure, would result in the dealer removing the engine, replacing it with one from the manufacturer, and then shipping the old engine back to the manufacturer for examination.  Yet he has three failures apparently.

So that leads to the possibility that there is no warranty on these 3 engines.  Why would that be, I wonder?  Have they been chipped, tuned, or otherwise modifed in some way?  How had they been used when they failed, and how good were the service histories?  He provides no detail whatsoever about any of that.

Now I am the furtherest thing from a Toyota Fanboi you would find, but there is nowhere near enough detail in this to make any determination about the cause of the failure.

i agree, would have thought Toyota would do a post mortem and sort out root cause.

Was researching yesterday, and the new emissions standards are in force, meaning 4x4 (class 2) light commercials can only produce 210gCo2/km. I checked and LC300 doesn't comply. Maybe why they have gone with 0-20W oil to meet the standard? Seems like the logical change that may cause this issue.

Luckily the dmax complies! we can keep using 15W-40 and get 500,000km !!

Inline sixes are the future apparently...

Business opportunity... buy as many V8s and ram 2500s as you can afford, they will be worth a packet when they are no longer produced! (as of now!)
