I mostly natter on the "I would just like to say" thread. There they know that we spend 6 months nearly in our place in France every year and for that we need long stay visas. Forgot you don't go there much.

I'm not sure when they came in I thought it might be 2009 but I may well be wrong.
It would be interesting to see stats covering whether the V6s started blowing cranks when the DPFs came in or not.
does yours have one?

Ah I see , bless u and indeed don’t often go there, , do see if anyone tags me , must read that
thread

That’s awesome mate in living there for 6 x months ,

Must confess I thought the DPF didn’t come onto any uk 2.7 models until the D4 was introduced , think there was a cross over in 2009 from the D3 to the D4 later in 2009 so maybe that’s where the 2009 comes in

I think there was a commercial D4 model offered in 2009/10 that had the 2.7 TDV6 but 3.0 in the rest of the D4’s, AD blue for the 2016 D4’s ,

At the end of the day JLR won’t admit there was an issue with snapped cranks etc and never seen them offer a solution to why , seem many D3 owners where there vehicle has wanted for nothing yet snapped the crank, also seen where some have replaced the engine and for it to happen yet again

Seems to happen very rarely in the jaguar and Citreon models , wonder if maybe they have different cranks as surely there’s a reason they have a far lower fail rate over the D3/4’s

Of course happy to be corrected about that , lol

Yes @gstuart and when he goes back to France we all raid his wine cellar 🤣


On the topic of d4s beautiful looking bits of kit but I don't think I would take the risk.

In that case need to get a few trailers to see how many boxes of wine they will hold , of course for testing purposes, 😂

Me neither on the D4 3.0 , along with the crankshaft problems also seen problems with both the turbos

Saying that my Dream motor would be the petrol jaguar 5.0 V8 D4 , getting the upgraded chain timing tensioners fitted , plus being a jap import replacing the instrument panel dials as they displayed in KM

So in reality they go between 25-30k , dial replacement 1k so well out my reach, never know maybe one day as they start to come down even more in price

Think as there ULEZ compliant that’s what is keeping the prices high as a 3.0 D4 are around half the price

Do you watch auto Alex they altered the d3 to look like a d4

 
We used to get Police & HA Disco 4's in for service, most if not all had DPF's - we never had any issues with engine failures, they were generally pensioned off between 330-350k miles.
The HA ones were mostly plodders, the Police ones not so much.
Personally I'd have no hesitation in buying one with a higher mileage - above 15k/ p.a. I think I'd be hesitant with a lightly or sporadically used one. My 2.7 Disco 3 had 165k miles on it when one of my sons took over stewardship, still going strong and doing about 20k a year.
 
Appreciate all the enlightenment. I've watched the videos including a couple by L R Time where he suggests that the crank issues were likely caused by football matches going the wrong ways resulting in moody engineers on Monday mornings. Definitely I will be changing oil every 5000 miles whatever.

To my question though about the crank, there's no answer is there. I have an enduring affection for the Disco 4 and its ability to transport seven in comfort at speed in a certain style. I bought a D4 new in 2010. Old style gearbox. It was left hand drive and I picked it up from the dealer at the Eurostar station in Belgium and packed my four children and bags into it to big a few years living out. I never imagined there were any issues and there weren't but now it seems we are rolling the dice. A used example is the distillation of driving style, maintenance and the supposed Monday morning crank. If all three collide in one car you have the grenade referred to earlier but if you like the package enough and as Ian M says, you're not borrowing the money to buy the car and then borrow more to fix it then it's okay.

For what I want, I don't see another car that would work as well and though I love the L322 my wife does not agree and it doesn't' have seven seats. I find it fascinating what the Disco 4 prices are doing which flys in the face of the crank scare stories. All the sub 45k mile examples I've been watch recently at around £30-£35k have sold. Just shows that JLR screwed up when they didn't evolve the D4 properly.
 
I know a person who thinks that the crank problems are down to the lack of tabs on the bearing shells. Which I find hard to believe are not there in the first place.
It'd be a bit of work but one could take the engine apart and put them in oneself.

Didn't lrtime (or might have been someone else) take a broken crank out and state the shells hadn't moved?

Maybe, dunno. And have no idea why my mate thinks this. I suppose it is still possible that shells with no tabs could still have stayed in place. But tabs on shells are soooo flipping basic why on earth change them? Except for a tiny saving in manufacturing costs.

Makes it easier to put them in the wrong way around 🤪
