TDV6 camshaft failure.

My father has a Disco 4, which has just blown up the second engine in two years. This one is being replaced under warranty by Land-rover, as it is the same failure as last time- the cam shaft.

Is this a known issue, and are there easyish preventative measures? ( other than driving a proper tractor, but he like luxuries like air conditioning too much..)...I did have to pull him out of the snow last winter!

Are you sure it's not the crankshaft as that seems to be a common failure.

No, I'm not sure now.... It was a phone call, and it was mentioned in passing.

It will almost certainly be the crankshaft, never heard of a camshaft failure on the v6s.

This is what stopped me from buying my friends pristine 2016 Discovery 4.

"Like driving a grenade with the pin pulled" said my local specialist.

Shame as it was a lovely example. He had no issues selling it, so l must have been in the minority worrying about it.

I think you will find outside of the Land Rover world very few people apart from mechanics know the issues with the Land Rover engines.
It is only when they blow and people get googling they find out what they actually bought!

It would be interesting to know how many have failed, against how many have been made. It's obviously quite a few though, or we wouldn't be talking about it. Are there any figures around?

I think people have tried to find out before, and the die hards say it is not many out of all that were made, but I suspect the actual figure is quite high.
The point people seem to miss is, crankshafts should not fail end of, especially on such low mileage vehicles.
Plus being a sceptical bar steward I always think the ones playing it down have a vested interest in the cars, either they own one or they fix them, and neither wants to see the value drop.

30 plus years i have been in the hgv trade and I can recall two crank failures, two out of literally thousands of trucks.

Theres a team of scammers offering to fix broken lr engines in Wolverhampton. They also work from Telford. They advertise on different sites including ebay using different fake names and fake locations. Be careful who you choose to fix yer motor. Check with us first.

I have a 2017 Discovery Sport and camshaft failed after 30,000 km. No warranty… it must be a defective part… any thought on recourse?

Could just be a shortage of lubrication. Unless you mean a crankshaft, see the above.
Welcome to the forum by the way.

Definitely camshaft. It was -40 so lubrication could be an issue. I wonder if that would be covered by insurance?

Discovery Sport has a different engine, with it's own issues....

There are so many potential causes, including lack of servicing, wrong oil, oil pump or relief valve failure, oil dilution etc. etc. Don't just jump on the failed part (which may well be a consequential failure) and assume it's defective - and TBH, it's not going to get it repaired. You need to find out the cause and work from there to get it resolved. I doubt very much you'll get any contribution from JLR unless you have full dealer service history, and even then, it's not one of the 'usual suspects' so unlikely to attract any financial sympathy.
