It’s taken 436 posts and 22 pages but I think we’ve successfully proven that no one on this forum is helpful and that OP is by far and away a high value individual and we’re all betas.
Now to match his post length with some AI drivel:

Hang on - will check my spare heater box in the garage.
Levers fully towards driver, air goes through the heater matrix. Fully towards engine cooled air bypasses matrix.
It's simply not gramatically correct, so the sentence does not mean anything. The intent might be correct, so write it properly, or do what other non natives do and appologise for their English upfront.
So with exhaust leaking while pump is running the diaphragm almost certainly needs doing. It was probably that failing that killed the old pump.
Valve block has to come out to do it as the valve sits between the blocks highlighted below. The...
+1 on check for white powder - if there is the dryer is breaking down & either needs replacing, or new dessicant.
Diaphragm leaking could be either dryer powder preventing it from closing, or a split in the diaphragm.
Full valve block rebuild...
Take the little exhaust filter out & check if there's air from the port while pump is running. If there is, then the diaphragm valve is leaking. That valve is on the same 12V that the pump uses, so it should engage together with the pump...
Clearly you are rather over sensitive to anything contrary to what you think you know. Most of the comments early in this thread were why it might not be a good idea. You took them as direct critisim rather than answer in a technical manner...
If it went down one of the oil returns, chances are it's in the sump ? From that angle, my bet would be it bounced on chassis or drive shafts & is lodged or stuck to an oily bit below. If it hit the ground it could have bounced anywhere...
Cycle the ignition a few times without starting. On mine I can usually hear the motors moving after a while. The docs say it self-
calibrates every X hundred uses, but who knows what the real number is !!
So many words with so little meaning plus a one month trip in view. Must be retired or a politician to have that amount of spare time. If retired, then from an age when swapping bit on cars was a simple thing to do. Not so now with all the...
Last year I put vacuum on my Blue P38 AC system, but didn't get round to having it gassed. Re-checked to day & it still has full vacuum, so hopefully gonna get it done this week. Green P38 AC is nice & cold, so that one is getting used...
The other next steps is a banch test like this: https://www.landyzone.co.uk/land-rover/97-p38-gems-eas-issue-which-seems-to-have-expanded.387706/post-5576496
GEMS has an additional cover plate, but I think the 1999 onwards it's part of the sump on Thor engine ? Not sure about diseasel though. The bell housing inspection plate should be enough to see the flex plate on all types ?
Yes you can just fit one scrader valve in place of the compressor, but you will also need to activate the diaphragm valve to fill the tank. This also assumes there are no other leaks. The problem with this approach is the tank will get...
