I have a proper medical one that I used on hydraulics. The owner actually bought one and the noise appears to come from the front top end he tells me.

I agree, have asked him to run back through exactly what happened and what the garage did and said.

As with Bob, on an engine that’s had an oil pump failure I’d be wanting it tore right down and check everything.

I asked him for a run down of what happened and a video of it, should get the video tomorrow.
His response: "Main thing as I can deduce was starter caused pump chain to break a tooth as the pump that I actually have turns a part way then seizes as I recall motor was running superbly before I switched it off and on restart it made a noise hard to describe but maybe like chain drive to pump broke a tooth or gear then I gave up knowing it sounded serious but got it relayed home ."

Does he the original oil pump?
If so, are it's mountings still intact?
And was the oil pump chain still intact?
The only way the main timing could get damaged, is if the oil pump chain got caught by the main chain.
It's either that, or it's the main chain that failed, and taken the oil pump out.
However, without seeing the original parts, it's hard to pinpoint what has gone wrong, and what the likely damage was.

From that, I don't think anything would be catastrophically starved of oil, i'm not sure why the top end was worked on but i'd be checking the timing is bang-on and the injectors are in the ports they were originally. The timing being out even slightly can cause excessive diesel knock without materially affecting the valve-piston interface, as can injectors being put in ports with different codings. As I previously mentioned, the pump phasing needs to be correct.

Same for me - I do remember pretty much every PSA/Ford diesel HP pump had to be phased correctly or risk belt/chain breakage or stretch, the only exception was the 3.6 TDV8 'Lion' which has 120 degree opposing pistons rather than the more common 180 degree ones.
ETA - as much as I hate 'youtube for everything' this screenshot shows the timing link and the corresponding drilling on the pulley.
As you can see from the bolt pattern even though it's a keyless taper, the bolt pattern is 'key' to getting everything in the right place.

These engines are well known to be a load of ............ troublesome.
Sounds like oil pump or chain failure, which has done the timing chain too. Might have slightly bent one or some valves, who knows ?
I am no fan of garages, but taking on a job like this, they are on a hiding to nothing, as you have to go though absolutely everything.
They should have refused the job, or fitted a replacement engine. Once the chains have jumped or snapped it becomes a can of worms, and the cost of sorting it out properly at the rates garages charge, makes it prohibitive.
Best solution is an engine transplant. This engine never really suited the Defender in any case.

From what I remember, the pump flange/sprocket was essentially a carryover from the 2.0/2.4 TDDI's, so still had the timing holes/slots.
If I get a chance tomorrow, I'll have a look at the manual.
