TDV6 crank and crank bearing failures

[jakeslouw]

Hi all

Disco 3 owners in South Africa have started experiencing more and more crank breakage and crank bearing failures on the TDV6.

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.

If I recall correctly LR UK have acknowledged this issue and have formally communicated this.

The correspondence was listed on either the Disco3 UK Forum or the RRS UK Forum - I would be looking there for information.

Hi Garry

Yes, we're talkong to the UK forums.

The issue is that LR is trying to imply that these are extremely isolated incidents. They have also not issued any general recall.

LR South Africa also tries to claim negligence or abuse even when the crank fails within warranty, and it takes legal action for them to then repair.

So we're trying to determine the number of incidents world-wide and then attempt to correlate that with sales numbers, among other parameters.

Good luck with LR SA. I had my out of LR warranty 2005 TDV6 engine pulled apart at 95,000 k's for a different unrelated reason and the mechanics found a number of bearing caps were only finger tight when they checked them. I was lucky another couple of hundreds kilometres at most and it would have seen a rod or two plus the crank smashed, so the engine was saved from failure just in time.

They never said the bearings were worn out, rather the bolts holding the caps had come loose.

A number of years ago quite a number of so called TDV6 bearing/crank failures happened here that were reported on the forum, funnily enough you don't hear about it much now. I reckon mine would have been a rear case in that it was pulled apart just prior to failing, rather than just after when everything was to wrecked to properly diagnose what went wrong to cause the failure in the first place.

As I said good luck.

I was under the impression that many of the failures in South Africa were down to:
1) incorrect oil being used ie 15w/50
2) dealer service intervals of 25,000ish km (way too long)
3) difficulty in obtaining high quality oil that meets specification

We have much shorter OCI's here in Australia (ie 15,000km officially) but many of us change our oil at far shorter intervals than that, even, so we don't seem to get a lot of failures.
TerryO's type of failure is not common but not unheard of on the earlier 05-06 TDV6's.
Far and away the most common type of failure I've personally read about is the oil pump breaking at the timing belt tensioner mount, releasing the timing belt and destroying at a minimum the upper valve train, although our dealer here in Adelaide claims to have never heard of the issue.

Not sure what you base your (in bold) comments on Rich? There have been plenty of bearing/crank failures reported earlier on in the life of the TDV6 in D3's both here and overseas.
Land Rover reportedly fitted the later model 3.0 litre bearings in 2009 to their TDV6's to try and stop the failures and as. I said mine didn't fail, the problem was found before it did.
