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.It’s often difficult to diagnose exactly where a noise is coming from on an engine, a cheap stethoscope is great to narrow down the area.
If it was me, I would, unfortunately my friend lives in the central belt and is now of an age he is reluctant to lift engines out. He ran a 200 tdi for years and did everything to it.Its never going to get fixed using armchair diagnostics, hoof the thing out of the engine bay and strip/check everything. Bottom line is this engine has had an oil pump failure, I personally wouldn't be happy until its been gone through properly.

Valve and piston would change with engine revs though as rotational part.
Same as small end rattle.
But if not starting that wouldn't just be oil pump failure.
That's more like locked up and jumped the timing etc.
There is more to this story than "oil pump failure"
I agree, have asked him to run back through exactly what happened and what the garage did and said.I can't honestly remember the setup, it does sound like there is a missing or damaged 'O' ring between the cylinder head & the camshaft carrier which would give low oil pressure (with resultant noise) from the top end.
I agree with the above, there is more to this than oil pump failure.
I have asked.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 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.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.
