I have now finally got the engine back together.
I had difficulty in getting the seal right on the front injector pipe. Turned out there was a bit of an o-ring that had got squeezed and disappeared.
Blew the pipe out, but never noticed the missing part.

The good news:
I have taken the car for a short spin. The thermostat seems to work fine, no leaks, quick warm up, cooler running. Still have to do a longer run, because:
The bad news.
I have picked up an (more) engine fault(s), yellow light on. The car runs fine, but a little rough, and then it will loose a bit of power. There is black smoke from the exhaust, as if unburnt petrol.
The question(s).
1. If I have lost petrol pressure and this triggered the (yellow engine) light?
a. will the light stay on until cleared?
b. will this cause the engine to run in limp mode until cleared?
c. can I re-set and clear the engine light without special tools?

The advice.
Before you undertake a strip of the engine, take many pictures, and make sure the light is bright and the pictures sharp. It saved my bacon with the connection of supply/return petrol and also with the one wiring loom where I could not find the corresponding connector. Turned out to be on another wire hiding behind the rear bank of cylinders. Easy! (, if you know how.!)
