I phoned Millers Oils and they said both the 0W and the 5W were suitable for the V8, there was no advantage for either.

So if the guides are aluminium, do the newer ones have steel on them to help reduce wear?

I'm hoping to keep my V8 as long as possible and I have put money aside for when mine fail.

Thanks for that, very interesting.

At least I now know it's not an oil problem (although regular changes wont do any harm) and the new guides have been uprated.

Does anyone know the approximate cost for this job?

My guess is, as the car gets older it will be an uneconomic repair.

The new tensioner is easy to spot as well, the 'piston' is at a slightly different angle to the earlier design.

This suggests that the earlier cars are just as likely to suffer from the same issues unless they have had the guides and tensioners replaced with the 'new' design ?

I have just read a interesting article by a Land Rover specialist in the USA.

They reckon 2010 - 2016 motors are the most at risk and its a $5-6k repair
.
If a cam chain slips and ruins the engine then your looking at $22,500 plus ancillary parts and labour. (2019 prices)

The chains are lubricated by oil spray tubes so clean oil is essential and they have been recommending 7500 mile service intervals although they are considering 5 or 6k.

So even with the updated guides and tensioners regular oil changes are recommended.

The 'US' model year updates are usually a year behind the UK, so I would interpret that as 2009-2015 in the UK ?

I will see if i can find any info when we are back at work, see if there are any technical bulletins or advisories that shed any light on the issue.

Hi, did you manage to find out any more info?

It's just a shame that there isn't an answer somewhere, like 'the problems were eliminated after Nov '15' or something. (I have pulled this date from thin air, don't read into it.)
