Thread: TDV6 crank and crank bearing failures

12,000km for the 2.7 is not really extended.

As I indicated there are some very early failures but they are the exceptions - in statistical terms they would be outliers. TerryO a few years back had to have the sump dropped on his 2.7 and the big end bearing cap bolts were loose - so really an assembly issue so this may have been the cause of the early failures.

These seem to occur anywhere from new to out beyond 120,000kms

So I'd like to politely ask if any forumites here have had such a failure, whether you would post the following details:

- Disco 3/4 model
- manufacturing year
- mileage when failure occurred
- dealer services intervals Y/N and if no, how often on engine oil replacement
- If non standard engine oil spec, what oil and grade
- description of failure
- repaired under warranty or not
- response from LR if any
- anything else that can assist such as any oil additives, even diesel ppm

We're trying to build up a database of incidents world wide in order to try and determine a pattern or causal effect.

Thanks in advance.

Yes had a failure. D3 2.7 TDV6 MY08 Manufactured Nov '07. 155k on odometer at the time. Full service history by independent LR garage. Pulling 1500kg camper trailer along flat stretch of highway at time of failure (~100km/h) - heard "whirring" sound, no throttle response for a few seconds, then shut itself off (bit scary on the highway). Not under warranty and repaired out of pocket. No response from LR Australia.

Mate’s VW Golf petrol melted a piston which apparently is not uncommon and he got diddly from VW.

Consider anything that is doing city miles is running in ‘arduous conditions’ and service accordingly is a good start.

This article has LR Sth Africa saying that from 2012 there was a design change - " Changes have been made at a production level and all new engines manufactured since 2012 use a new bearing design. Dealers have been briefed on the procedure for any engine that experiences this issue."

Although there have been owners on here with post 2012 vehicles with sudden catastrophic failure with good service history and not high k's.

Interesting article.

My 2016 SDV6 got oil and filter every 12k kms, at a LR dealer so probably using the correct supplies, and it did the crank at around 70k km.
Good servicing may reduce the risk, but does not eliminate it unfortunately.

Sorry to hear that mate. I can't see that 10,000 k or even 6,000k oil and filter changes would have saved it. They just let go.
