Odds of a JLR 3.0 TD V6 croaking?
Discussion
Mulling the purchase of a RR Sport TDV6.
Plainly there is an issue with the engines, but are there any stats on how likely a failure is? Is it similar to the oft quoted 5% of total production affected re Porsche M96 bearing failures, which has dropped as the cars age?
Is there an ‘infant mortality’ angle to it like the Porsches ie if it’s made it to say 10 yrs old/100k miles (plucking figures out of the air) then is a car more likely to be ok?

Mine (in a 2009 Disco 4) made it to 150k before failure. I put a 2nd hand engine in with 80k miles. Regular oil changes, good quality oil - but still they can fail at any point in time. I drive mine very gingerly. No quick take offs, no hard acceleration. I imagine it's the torque that does it. My first one went on a hard acceleration out onto a busy roundabout. I just need it to last another 3 years!
There are a huge number of these engine out there, but an awful lot have failed at all sorts of mileages and ages. JLR say it is something like 3%, but that will only be those that are in the care of a JLR dealership. A significant proportion will be out of the system now and failing.
The only way to own one of these and not worry about it is, if you have very deep pockets and a spare vehicles or you live in total ignorance about it.

We have a 2013 Discovery HSE for towing a single car trailer. Has 240k on it and nothing major has ever failed under our ownership (owned since 2018 100k). Has never seen a Land Rover dealer as previous owners were Enterprise Car rental and a family.
On the other hand we would still not recommend and JLR products unless they have warranty.

My XF SDV6 ate its crank at 88,000 miles - Engine was totaled.
Not what I wanted to hear. I had heard about oil dilution as an issue, but had understood it was the extra weight of the LR models that caused the crank issues, with the J products not really affected?Edited by covmutley on Monday 30th September 11:50

If it's already forming a question in your mind, then that engine isn't for you.
The only way to own one is with blissful ignorance.
Its a curious one... I own a 996 (my second) and was well aware of the issues the M96 has when I bought them, and drive it without worry.The only way to own one is with blissful ignorance.
Its the apparent randomness of the crank issue that's troubling me, unrelated to mileage or condition. But I really like the cars and am trying to quantify it in my mind. Failures appear more common from forum posts vs porsche IMSB related failures, but that may be because there are many more of the cars around.
This is a pretty informative video on the crankshaft issue and other potential failure modes presented in an amusing manner:

A potential cause being William forgetting to turn the temp up on the heat treatment oven after Man Utd lost at the weekend was particularly amusing

When I saw your first post I knew you were already 90% sure you were going to buy one even when you 100% knew they are trouble Its the apparent randomness of the crank issue that's troubling me, unrelated to mileage or condition.

I've watched a lot of this couple's videos, he sounds like he knows what he's talking about. He advocates using 5W/40 oil instead of 5W/30, I've no idea if that's a sensible idea or not?https://www.youtube.com/watch?v=v3moekbW6z8&t=...

I own a late Discovery 4 (2015 MY), which is still under LR extended warranty and I have just renewed the warranty for the final year. I wanted one with warranty for piece of mind.
Thankfully I have been lucky and it has proved to be very reliable. It is nearly 10 years old and 100k miles and it has only needed a coolant reservoir and new boot latch over the past 2.5 years and 25k miles.

I’ve just sold my 2013 RR Sport SD V6, with 99000 on the clock. I bought it six and a half years ago with about 20000 on the clock. Other than needing a new inlet manifold about a year ago, the car was faultless and everything on it still worked properly. I had it serviced when required but apart from putting new tyres on and some new discs and pads, there were no other major costs.
Maybe I was just lucky to buy a well built car.

That was fascinating, entertaining too, thanks for posting. https://www.youtube.com/watch?v=v3moekbW6z8&t=...
