Tarka is sorted, hideous squeal eliminated. I'll collect the car on Friday.
The source?
Nothing that we considered or discussed.
One of the auxiliary devices driven from the front of the BMW N62 engine is a vacuum pump. This provides vacuum for the brake servo and on a BMW car, other functions: there are 2 vacuum ports in the pump. .
On a Morgan Aero the second vacuum port is caped off.
The cap split: what we could hear is air being sucked through the cap.
Replacement? Less than £5.00
Labour? 5 .5 hours.... Bonnet, Cowl and 1 wing off. The pump is low down on the off side.
Williams discussed this issue with Morgan Motor Company. It is a "known but rare issue" !!
So, now all with the 4.8L BMW motor know.
If you car starts making a noise like a squealing fan belt, which starts intermittently but becomes continuous, it is very probably this problem. Of course, it isn't a BMW issue, but a Morgan one.

Colin,
I am somewhat relieved, although I'll be relieved of more than a few ££!!

Hello Peter,In my post I mentioned the vacuum pump, so you have to read your answers to your posts saves you a lot of money.Paul Paul, lesson learned, don't assume the obvious. I didn't even know the BMW had a vac. pump driven by the engine. Good to have someone here who know about the mechanical side of the BMW B8 in our Aero based cars. I see you are quite new here, so a belated "welcome!" Peter
