I understand there is a possibility of there being little enough damage to repair the engine but I managed to find a 2008 D3 2.7 with 92K miles (mine had 160K miles approx) from a cat B and it wasn't expensive, so I'm going to have a go (with the help of a very kind neighbour with a fancy garage and lift) of swapping them out.
It's a risk, but the other options become seriously expensive so for now this is the plan. And yes, I'll change the oil pump on the new engine .2012 Discovery 4 HSE Sumatra Black

since main and big-end bearings positioning do rely on tension of the bearingshells. it is proven that there is a bigger risk, ( although not always) around +/- 100 K mls.. a lot of these bearings spin arround that mileage.. in my topic you can see why... and how they wear...so losing tension...
bottomline.. change the shells now... with engine out (on a stand) ist is quite easy.... not very expensive
(island4x4 do sell interesting and complete bearing sets) and have another 100K + out of your then better engine..
yes i know there is alway's more you can do, but i like the fundamentals to be 100% Best regards

Hi, sorry to hear of your problems, if you are going attempt it yourselves there are some very interesting videos on YouTube by "piston broke" he has done several rebuilds on D3s and RRs you might find some tips there.
Using Mikey's guide two halfwits took a day to get the body off, the only casualty was a broken earth cable.
Most was straightforward, some thinking was required, some awkward as hell bits and some that made no sense at all.
I have another engine ready, a few parts to change over and some RHD/LHD adjustment to wiring looms it seems and then we try the next chapter

It's certainly a nice workshop, but my neighbour gets the credit for that.
The kids have been enterprising today in my not-so-Scandinavianly-tidy kitchen!

Old engine is out and parts swapped to new one, only had to move PS pump, alternator, battery cable (different length for LHD) and starter which is still out so we can do the torque converter install later.
I changed both timing belts and tensioners and the oil pump as the engine I bought had the old style hand grenade.
Interestingly, the plastic cam belt cover on the engine I sourced had a hole in exactly the same place as the one on mine, where the broken tensioner smashed into it. There are scrape marks on the inside too, so it's possible this engine suffered the dreaded fault in the past and was repaired. No issue really if it runs well, just an observation.
Next steps are to do a few small jobs including brake pipes and lower steering column (didn't survive body off) and put the new engine in.
It's all fairly straightforward but every job takes 3 times as long as expected 2012 Discovery 4 HSE Sumatra Black

Now would be the time to consider new bearing shells as well, it's not expensive to do and will give you further peace of mind. Having gone this far it really does make good economic sense too as you'd be gutted if it all went south later on.
A little disturbing though that the pump had failed previously on the donor engine, and then replaced with another weak style pump. If so, you can perhaps deduce that it failed prior to the new style pump becoming available.
I had considered the shells but it's also a question of time, I only have Saturdays, am using someone else's workshop and can't neglect the kids too much . I'll be happy if I get a couple of years out of it, so will take the risk - the engine had done 92K and may already have been rebuilt.
It's a lottery, but that's Disco ownership .
Also - the pump had definitely been changed so that was my thought too, long enough ago that they used the previous design. Probably about to pop!2012 Discovery 4 HSE Sumatra Black

Tomorrow (hopefully) the body goes back on and we test!
Only the front brake pipes to do, fill the oil/ fluids on the jobs list.
I've put together a parts and costs list for those interested. Bearing in mind that to get a 2nd hand engine here (difficult) and have it fitted would have been at least 10K (probably a lot more):
Used Engine (92,000 miles) £2000
Timing Belt Kit £59
Crossover Gasket x 2 £16
Rear Timing Belt Kit £35
Timing Tool Kit £30
Service Kit - Air/ Cabin filter, Oil Filter, Fuel Filter, Sump Plug £26
Aux Belt £12
Lower Steering Column £83
Steering Column Torx Bolts x 2 £3.50
Crankshaft Seal £4.50
Oil Pump Sealant £1
Oil Pump £107.50
Rear Brake Pipes £16
Plastic Trim Clips £8
Cross Over Pipe Studs x 3 £7.50
Oil Temperature Sensor £24
Crankshaft Bolt £7.50
Rear Mudflaps £62.50
Brake Fluid £7
Power Steering Fluid £17
Brake Pipes Front £20
Brake Hoses £12.50
Engine Oil £30
Coolant £25
Gearbox Selector Cable £90
Shipping Charges £350
A little over £3K.

Not sure you could bill 'rear mudflaps' into the rebuild
