I really would like to buy a D4, however have been largely put off by the 3.0ltr (even well maintained examples) potentially handgrenading and costing more than the car is worth to fix. Am I correct in saying that the safe bet (engine wise) is either the 2.7 or the 5.0?

If this is correct, why does the 2.7 fail in the D3 but not the D4, my understanding is that it is the same engine across both series...

Thank you in advance.

Oil pump was updated in the MY09 or there abouts 2.7 so they dont snap off the tensioner mount.

I’d be interested to know if they changed oil service interval to 12 months in the D4 as they did with the 3.0.

In my D3 it’s 6 months and I’d stay with that using only the correct Castrol Magnatec oil 5-30W A5

Go for the 3.0 SCV6 if you can find one...

The D4 2.7 was the most reliable of all the diesels,and if you need a bit more grunt a BAS tune will liven it up.

There were obviously some mods done,from the 2.7 engine in the D3,but no one really knows for sure what they were,apart from the oil pump,and a few other minor things.

Even in the FORD Territory that ran the same engine,there were very few if any major failures,cranks,etc.

The V8 is also pretty reliable if looked after,that is,serviced correctly.

Thanks for that, it is a real shame about the 3.0 (on paper it looks great), now to try and find a lowish km V8.

210800km on my SDV6SE 3.0 and going strong (famous last words perhaps?)

Oil service every 10k kms

Dude. The 3L is a POS engine in all realities, and I say that owning one. Between manifolds, throttle bodies splitting, turbos going, turbine control valves and the cranks failing, they’re silly money to keep running when compared to a 2.7L D4. That’s the point. When they go they’re nice but the upkeep is pretty steep compared to the other engines.
