D4 3.0 SDV6 catastrophic failure

I had all my bearings switched out at 270,000km on my 3L. I feel it was well worth investment.

Was this done just by removing the sump?

Yes and there’s a second collar as well above the sump pan. You’d be removing a bit of the front axle as well probably.

what sort of $$$ to get that done? I was going to get new oil pump, the 15mm impeller FordMCO version when the timing belts get done later in the year but may also consider bearings.

Theyre starting to lose the plot a bit I reckon! Its a typical phenomenon - Make an entertaining channel, get a following and then have people almost 100% believe every word you say.

Whilst the failures are claimed to be extremely frequent, based on the number of actual engines produced vs the failures - the rate is still quite low. Forums etc exacibate it

Even if its the forum phenomenon if you look at the pommy groups its nearly everyday a 2.7 or 3.0 engine is dead and being replaced, could be age related or just lack of maintenance.

Nearly every day out of how many 2.7 or 3.0 UK Discovery's?

Ignoring all the silly waffle / hyped up panic, I’d be interested to know is there anything fundamentally wrong in his technical conclusions / hypothesis of reasons of failures?

Looking at the UK forums, I’d say combination of both, combined with the batch of bad metallurgy they did admit to having.


LR home mechanics (loose definition) are rife on the groups and wow, cheapest parts, cheapest oil, poor practices…. Combined I’m not surprised the failure rates increased on the pages.

Sure, factory log serviced vehicles have failed, but they are few and far between.
