Thread: Purchase a D4 with replaced engine

I wonder if they can legally do this.
Not that I would want to try and have an issue resolved with that mindset.

I am kicking myself 'cos I can't remember where I read it..... it was a very recent article by a motoring magazine (Modern Motor?? I'll check) which had done an in depth research and discussion with Ford re their new V6 diesel based on their old 3.0 litre for Disco, Jaguar etc.

However they discuss the crankshaft and said it had been updated ... and.... that LR has benefited from the update to fit this crank into their latest 3.0 engines.

If this is true, and there's no reason to suggest it's not, then presumably if one purchased a new crank from LR then it will be the updated one. Is this the V2 mentioned earlier?

Food for thought.

That may well be JPSK Motors in the UK, I think I read them offering this service.
They have a fair bit to say about the shaft failures.

Some of the UK engine rebuilders are fitting Sputter Bearings.
Must confess as a (retired) mechanic I'd never heard of them.

Worth a visit to Google to read up about them.

LR may have received the benefit of the newer crank, though I doubt it was for the D4 - the original D5s had the same SDV6 right? And I don't know if the newer Ingenium is being grouped into the 'latest 3.0' designation?

I'm thinking the new crank went into the RR and Jaguar line, and later D5's all with the 3.0 diesel engine.

There were as many D5 engine failures as in the D4 so I severely doubt that

Yep, point taken, but I was more thinking/presuming/hoping it has been fitted to the very latest D5's in the past year or so.
......and is now supplied by LR as a replacement item for D4 engines......
(Wishful thinking maybe on my part! )

The D5 has been out for a few years now.

And I assume the only reason there is vagueness about this is because JLR are treading carefully around the legal implications of "admission to fault"
Which is a shame, but does not change much for any of us who have owned a D4 - there just is no replacement (no pun intended)

What we need to do is find a rouge JLR employee who can dish the dirt
