Writing a post like this is like writing an exam question. Many candidates dont read the question fully or understand.
I re viewed the LR time video.
the crank failure on Fabián's car was caused by...

Original owner changing the oil annually but exceeded the change interval by mileage.
ie poor oil quality
Excess cranking for starting (5 sec or more) caused by a failing fuel pump.
ie lack of lubrication to crankshaft while cranking.
So
check your oil pressure and use a thicker oil remember that no 5w30 oil meeting the original LR spec is made in 2024. and cross your fingers. Always listen to old people or when they die you will live on in ignorance.

Lots of other engines suffer a lot more abuse with a lot less damage.

And the vast majority of LR V6 diesels do big miles with only normal servicing and using 5W-30 oil at 16k mile intervals (or whatever the book requires for that model). 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

Ive said it before on a few other forums ;

1. Poor Servicing - not servicing the car correctly, eg leaving it to long in between services
2. Starting the engine and just driving off, you need to treat these cars/engines as they are a 1950s Jaguar, engine on and leave for about 10-20 seconds before engaging the gear box, let the oil circulate and if its even colder leave it a good couple of minutes to allow the oil to warm through the engine.
3. Heavy driving , over revving the engine putting unnecessary wear on the engine and crankshaft as the crank is already weak dont constantly drive the car at 4000+rpm , its not a rear wheel drive ford focus ST.

If you bear in mind the engine and crank are made of weak materials why force it to break.

Quoting from LR time " Oil " video and cannot find an oil here that is over the specified >3.5 sheer required.

Been studying the C6 Citroen ....a few crank failures but a lot of comments on bad oil pumps ???
and talk of running it for long periods over 4000 rpm causing the con rods to stretch distorting the bearing housing...who knows. Citroen will only supply short blocks .no pistons/rods or shells.
They specify oils 0w30 5w30 10w40 and 15w40 but I saw no climate ranges for each oil.
One guy at a LR dealership said all the broken cranks that had come in had low oil ..
Personally I dont see mine at over 3000 rpm Always listen to old people or when they die you will live on in ignorance.

Quick takeaway; RRS uses a sequential turbo setup while Citroen is a twin turbo setup (both run at the same time). RRS makes quite a bit more torque and a little more HP. RRS has slightly lower oil capacity. RRS has slightly higher max HP and torque RPM points. RRS weighs around 2500kg, Citroen C6 weighs about 1875kg.

The 5w30 ACEA C1 oil spec is essentially a Ford oil spec. ACEA decided to move away from manufacturer specific specs and go to a “these are the specs, manufactures choose which works best for their engine” system. I believe this is why JLR left the ACEA C2 backdoor, they knew C1 may not be stocked at a lot of places (I can get C2 off the shelf at a few auto shops in Poland, I have to order C1). 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory
Born and raised in So Cal. Moved to the UK in 2018 for a few years. Now in Poland and looking at moving back to the UK.

And in the RRS, that same engine also had a 190kW (254hp) version. And the L494 3.0V6 diesel increased that to c.300hp/516lbft. 2012 SDV6 - it's missing a couple of cylinders

Exactly, which is why I noted the years for the specs listed. Also worth noting is the later mentioned by RRSTDV8 also run the 8HP 8 speed auto transmission. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

As noted the earilier RRS 2.7 is closer in age and design to the C6, and Jaguar and the Pug.
Apart from the turbo setup. The cars have more BHP than the LR.

Interesting you found some Citroen failures. People say jaguar failures are rare.

Personally I don't blame the DPF as I believe cars without DPF also fail.
I think LR Times explanation of the short block (required for the French FWD cars) is the design problem


As for long cranking times. I think this is only at ~100 RPM? I worry more about the time it takes for the Oil light to go out. In bad cases this can be 5 seconds? and at 800?RPM a bigger worry
