Discovery 4 engine seized

[rob1]

I had the same problem last year, on a 2007 S type jag. Same v6 engine. Big end bearing shells moved seizing the crank. Apparently the problem became common after the introduction of DPF. Over fueling to clean the dpf excess fuel getting in to sump & then poor lubrication. JLR denied any existence of a problem. Again, a company that will never ever receive another penny from me.

B.T

all cars that have the engine have this problem but they tend to have less let go as they arent worked as hard in cars as in disco's

BMW have their share and more of engine problems. Ask @Penmoel about that issue with timing chains and wrecked engines. He's been bitten. Their plastic inlet manifold throttle valves are somewhat notorious as well.

The V8 M3 spins it's big end bearings too, friend is just having a new set put in his as a precaution, been advised by BMW to do this.

I don't know what it is with modern engines that don't locate their crank bearing positively. Whoever thought that was a 'good idea'? I remember Perkins having the same issue with some early 1100 series engines [I think they were].
Perhaps its only a small proportion of all susceptible engines that get any issue, but even a tiny percentage having a catastrophic issue is too many.

From what I gather the bearings are just very soft, no copper or what ever it is, backing to them either so you cannot tell they are wearing via oil tests apparently. He said that BM were advising them to be checked/changed at 80k miles but they I think spin up to just under 9,000 rpm.
Yes, it seems modern day engineers simply forget old techniques and try and re-invent the wheel every time. This day and age there should be no excuses for such failures in design of what is a very simple thing like this.
It's a bit like fillet radius on cranks being omitted and then they wonder why cranks break, rod bolts seem another problem area on other marques. Reliability of these modern cars seem no better if not worse than cars built 20 years ago.

Likewise. The only way to run a LR of any model is on lease so the breakdowns are somebody else’s problem. We had a RR a few years ago for 12 months. It spent more time back at the dealer than it did with us. We got a full refund off them. The last Disco was nearly as bad as well. It’s just the badge people want as the actual products are nothing short of crap.

I wouldn't go as far as that. My last Range Rover was superb and exceptionally well built and trouble free. Qualified by the fact that I didn't keep it for more than 40,000 miles and I recognise that I was lucky with the front diff. Ran a previous classic diesel to 98,000 miles without a hitch after a dreadful first year where the rear brakes locked up prematurely and LR [the company] arrogantly washed their hands of it. Its the dealer that saved the day back then, by changing virtually the whole system, half of it on another vehicle's warranty. I was daft enough to buy a Discovery to go with it in 1990 and that had a few minor build issues but was by far the cheapest vehicle I've ever bought new. It lost £50 in value over two years.

40k miles trouble free on a range rover and you call it superb?
A neighbour has a landcruiser with 370k miles on it, trouble free.
Just wondering what would you call that?[emoji1]

 

[bigrigg150]

discovery 4 with seized engine here.......being fixed at the moment, looking like its going to cost 7k......could of done it about half the price with a second hand engine of ebay but didnt want to take the risk of it going again.

 

[milkloss]

I’m guessing that’s why these vehicles have such low depreciation: the owners have spent so much money on them they can’t afford to sell them for any less!

Supberb in 40000 miles. Your kidding with statement sent you?

Wonder what might of happened going to 41000 miles.

The LR products are extremely poor across the board either mechanically or from a practical point of view.

All LR have done, very well I might add, is create a brand people want to be seen in irrelevant of whether that product is poor or not. It’s just excellent marketing.

That's all I kept that one for. I kept another one, that was like new when I sold it with 99,000 miles on the clock. In case you don't know it, I also have a Land Cruiser with 185,000 miles on the clock. So I know what they are like relatively. I bet your neighbour's hasn't actually been trouble free for those miles either, although it might be 'reasonably' trouble free.

That's your opinion. Mine is that I would not hesitate in buying another, although I don't currently own one. I owned a 110 hi-cap from new for 22 years and several others including a Range Rover for 8 years and 99,000 miles and none ever actually let me down. In fact the ones that left me stranded can be listed……

MG Montego, multiple times.
Land Cruiser Amazon 80 series, once.
BMW X5, three times.
Various Land Rovers and Range Rovers, NEVER.

Admittedly there's a bit of luck involved but the total mileage on all Land Rover vehicles I've ever owned must be about 600,000.

IMHO theres no that many of us that can boast we run money pit (Recent) LR vehicles on here.
The ones that cost more than say £20k atleast.
if you can then its not on the back of normal farming income thats for sure. Just my views of course.

I recovered so many of the darn things a few years ago i wouldnt touch one with a barge-pole

 

[Farma Parma]

Freelanders , defenders, Range Rovers, Disco 3's , equal amounts of them all.
D4's were just out when i packed that part time job in.
Not many TD5 Discos mind. even tho i did most of the Recoveries using a 02reg TD5 Disco & double axle BJ trailer.
ran this all over the UK at times. but mostly jobs within 150miles of base up here.
never had a single Hilux recovered in 5 years of doing that job.

Talking to a taxi driver the other day and he was telling me that they have one or two older Skoda Octavias in their fleet that have done over 600,000 miles on the original engines.

I'd take that with a big pinch of salt. 600k miles is around 4 times the design life of VW engines. Taxis are unlikely to average more than 15mph over their life, but let's be generous and say that they average 20mph. That's 30,000 engine hours. For a VW engine! For two of them. Hmm.
While they might be the original engines, just how many overhauls and repairs have they had?

All these mega claims can all be taken with a pinch of salt. Especially the ones relayed second hand.

You’ve set the gauntlet now then. Go and buy a Disco 4 or RR and keep the forum updated with how it’s going.

I wanted to buy a Disco 5 back in Jan17 but the dealer's saleswoman wanted to sell something else, so I bought something else, elsewhere. I have a propensity to try and buy British where possible but have no brand loyalty as such. I still have two other British built cars, a Honda and a Nissan. I think I've been fairly good to JLR too, considering that I've owned two Series3, two OneTens and three Range Rovers, a Discovery and a Jaguar XK8 over the years.

As it happens I found the original leaflet and accessory leaflet for the XK8 last light. Here's what it looked like inside. They don't make 'em like that any more, unfortunately.

 

[msheep66]

Well I have had numerous Defenders and Discoveries over the years and apart from a Disco 3 which had more than it should have faults the rest have been very reliable. Perhaps I have been lucky but I have always kept up with servicing religiously.

Its probably the opposite. People who have had major issues have been particularly unlucky. That's not to excuse their traditional build quality issues or the occasional known fault, or indeed the attitude of LR to righting their wrongs, all of which could and should be acknowledged and addressed. Speak as you find but I've found build quality to be excellent nowadays.

Its well known that current top models this minute are having issues with software. However most new models have software issues and, while annoying, they are eventually resolved by updates. The main current issue is the new split screen system which will be amazing when they get the new software rolled out.
