Are you suggesting that there might actually be some very sound owners of Disco’s, 8 years out of warranty, that don’t go straight back to the manufacturer demanding a “good will” new engine, with the threat that they’ll buy a a new Kia Sombrero next time?! 
I hadn’t considered that possibility 
You’ve got a load of valuable experience to draw on with yours, is yours the original engine? 2011 - 2015: 3 x FL2
2015 - 2017: 2 x D4
2017 to date: FFRR SDV8
2023 to date: FL2 as a second car
2021 to date: Hinckley built ‘14 Triumph Trophy 1200
2022 to date: Hinckley built ‘14 Triumph Trophy 1200 & sidecar!

Depends who you talk to 
Indy close to me, not unusual for them to have three/four a month, Disco/RRS.

Unfortunately, even good anecdotal evidence still doesn’t give us that vital failure rate, per 1,000, per annum 2011 - 2015: 3 x FL2
2015 - 2017: 2 x D4
2017 to date: FFRR SDV8
2023 to date: FL2 as a second car

Engines these days should be good for 250K+ especially decent size diesels that have been looked after. saying that PSA have a habit of making soft engines.
I helped a mates son out when his psa engined ford fiesta shredded its belt, removed head had valves checked and reground as i could see there had been very slight contat with pistons and i mean slight, head was also skimmed but when put back together could not get it started, took me ages to come to the conclusion valve timing was out and thought i was going mad after about 30 times setting the timing. I took the chance and ordered a new cam, put them side by side and some of the lobes had spun on the camshaft as its not a solid cam but a bar with the lobes sweated on. what kind of company does that. fitted cam and the rest is history.

Has anyone ever gotten a figure for that?

My point exactly, none that I’m aware of. It’s all anecdotal 2011 - 2015: 3 x FL2
2015 - 2017: 2 x D4
2017 to date: FFRR SDV8
2023 to date: FL2 as a second car

Stumbled on this Autoexpress writeup of the TDV6 whilst looking for numbers.
It suggested the cause is
Quote:In rare cases the main crank bearing shells can rotate and cover the oil way, leading to the crank seizing, or if you are very unlucky the crank could snap. Any rumbling noises from the crank area should be investigated.
Wonder how difficult that is to check?
If it’s pretty straight forward, worth including on an inspection schedule?

Its just wrong, i cant see a massive cost saving the way they do it.
On the crank issue do we know if its an oil pressure problem that starts to rotate the shells due to lack of lubrication or the shells just rotate due to no stop in the caps ?
I am looking into a oil gauge to fit to mine just so i can keep an eye on it.

I've given the figure multiple times but nobody wants to believe it. This site is a magnet for talking about it or for those unfortunate enough to experiences it to tell the world ...even when we have done a poll on here of how many cranks have snapped they are measured in the tens ...not hundreds or thousands.

I’d agree that the impression that we get must be well out of kilter with the actual chance of failure, but I’ve yet to see any official failure rates.
In fact, I doubt LR would issue them as someone would only use it as a stick to beat them with, no matter how good or bad they might be. LR really couldn’t win there! 2011 - 2015: 3 x FL2
2015 - 2017: 2 x D4
2017 to date: FFRR SDV8
2023 to date: FL2 as a second car

I agree entirely with that, DG. The majority who have no trouble about this or other issues tend to get on with enjoying their choice of LR and if a problem develops, deal with it. 2014 MY Discovery XS Indus Silver. Sadly gone. Second last LR of forty eight years continuous ownership.

Yes perhaps because they are not officially published by LR. There are others here that would know that the 8/1000 or 1/125 or however you want to portray it is the figure from reliable little birds and this also ties in with overall failure rate from other 3rd party information like WD.

A £12k replacement engine does that 
Quick question for Disco_Mikey:
What would a ball park cost be to supply and fit a new engine in the event of a failure, as I have got a lovely low mileage 2016 D4 landmark which I planned to keep for a long time, but need to look at factoring in the cost of a new engine if mine fails, it’s still under manufacturers warranty until March, but don’t trust the after market warranties as not had good experiences in the past. So its likely to be a self insure, or look to change brands and get something different whilst the D4 value is still relatively high.
Thanks in advance
