Startup noise and smoke is normal. Immediate start is fabulous!

Very common symptom of clogged fuel filter. What is its history?

IP has a bushing at the mainshaft pulley end. It will wear oblong and cause leaks if it is run with the belt too tight. At rest, you should be able to twist the belt easily 45-90 deg. with your thumb and finger.

I don't really mind at the moment, maybe pull the engine out next year and rebuild it but for now I would like to just drive it for a bit.

Could be a sign the rings are not sealing, a good possibility after sitting for >20 years. At least the oil control rings. If it starts easily, equally when cold, warm, and hot, the compression is probably good. Would be interesting to do a compression check if possible.

Kind of rare for the injectors themselves to leak at the seam unless they have been incorrectly serviced. Look closely at the small diameter spill hoses, and the end plug. They start to weep with age. Sometimes the small niipples on the injectors can leak and need to be carefully tapped in.

Very good sign of engine general health there that it starts well.
With the external cold start cable disconnected, IP internal spring pressure defaults the mechanism to warm setting and keeps it there. Does your IP have the altitude compensator solenoid?

IP should have a clear line (probably yellowed by now) between it and the fuel filter.

So far no runaway situation so can't be too much, but maybe this could be the problem?
|
IDI diesel has no rich/lean as known in the gasser world, but excessive crankcase oil or vapor ingestion may be causing a partial runaway condition but doesn't seem to be a problem in your case.

How are you measuring this? Some blowby is normal. What happens if you unscrew the oil fill cap and just set it over the hole (engine warmed up)? Does it stay there and rattle a bit or does it blow off the valve cover like a geyser?

Not sure what your measurement describes here. The entire crosshatch pattern section on the dipstick roughly correlates to 1 liter.
I personally dislike oil consumption over 1 liter per 1600Km but I suppose a hard limit would be 1L/1000Km.

More like fuel starvation (clogged fuel filter or other fuel supply issue) can cause smoke (counterintuitive I know) and power loss at high RPMs.
Overall my first thoughts is that your engine is basically sound. Possible excessive oil consumption. Rings might reseat themselves after some spirited high-load driving. Apparently it has had a history of carbon buildup (as seen in the intake manifold). Diesels like to be worked hard (after warmup) and an Italian tune-up might help burn off any carbon impeding ring sealing.
Been a long time since I've driven a D24 N/A, but seems like it should be able to reach 130-135KMh? Might take a while...
Your transmission does not have OD?
