I see you have had no reply, I have rebuilt many different engines in the past although not that older JTD which I am guessing is only an 8 valve which should make life easier.
If you have the Engine Series number from the chassis/Vin plate, I can probably give you most of the torque settings , plus cam belt timing details etc. if it is of any help.
Is it possibly 182 B4.000 ?

The engine in question is exceedingly durable with just basic servicing throughout use.
A used engine will be far cheaper than a rebuild.

While you are correct that the engine is durable with regular maintenance (this one has done more than half a million kilometers and still runs very well), eventually wear and tear (lower compression, smoke etc) will have its say and the risks involved with buying second hand, unless a complete, honest history is available (possible but difficult, why is it for sale etc ?) mitigate the price advantage when long term ownership is the goal (three or four years to classic status ;-)))
I appreciate the advice, but I have my reasons.

Ok there is nothing complicated or exotic with the engine in question. Rebuilding yours will be easy if you can find a machine shop to do any machining required.

I agree , the old school engine machine shops that would do crankshaft grinding, reboring, lathework, valve seat and guides,etc. are going or gone.
Luckily for me the last ones I did were Iveco Sofim 2.8s and even with high mileages the crankshafts just needed new bearings and after honing I didn't even need new pistons, you could still see the original cross hatch marks from the factory in the bores and no wear ridges like you used to see in the old days, so just new rings carefully gaped, I have a nice Sykes Pickavant valve seat and valve cutters, then just a light grind and a valves good, shims as necessary, gaskets, assembly and oils, then on the button.
Trouble is nowadays modern engine design doesn't really lend it's self to that and even if the Dealer technicians can do the job, it is not cost effective so they just throw in a new engine at great expense to the customer.
Probably hard to find a machine shop to skim a cylinder head.
