Thread: Running in new D4 motor

Agreed, especially given there have been D5 engine failures.

Yes this is possible Dazza, but I doubt they pre-build more than a few months supply in advance - JLR certainly didn’t have enough cash to pre-order the D5 engines for years in advanced. Likewise, Ford wouldn’t pre-build and hold for JLR either unless they are being paid to do this.

Most engines are assembled just prior to being fitted - possibly 2-4 weeks in advance - and part supplies aim to be just in time. But yes the crankshaft and bearings would be batch produced and so will take longer for any changes to flow through.

Any crankshaft design and manufacturing changes could have gone into the MY19 and MY20 Discovery 5, but it may be too early to know if this was successful. Regardless, the D5 service intervals won’t be helping.

Different story for crate engines intended as spares though - these clearly need to be pre-built.

Hopefully Art can find a date and time on a tag somewhere on the replacement engine as it will be interesting to know if this is old stock or a more recent build.

To be sold in Australia, you must be able to supply all parts for 10 years after the models stop. So you should be able to buy an engine until 2026?

Are you sure about that?
There was a thread on here about Puma gearboxes now being unavailable.

This references “many years”. The US mandates 10 years.

I've been told a few times. Never looked into it. I had an 11 yr old bike that needed parts once and they used the excuse it was past the law requirement now.

So "many years" could mean anything.

I agree,it should be 10yrs at least,and mandated.

Yes maybe true but the supply of diesel engines to JLR would have been a small quantity compared to Ford globally and other manufacturers. Fords Bridgend plant made petrol engines for JLR and ended production in 2018 - 2020, so again my guess is the same for the diesel engines, round 2018.
