I have a similar noise in my 87 XJS V12 and would be interested in any
assistance in finding the source of the noise.
I am not interested in the petty bickering that seems to surface now and
then.
However, when posting a request for help it is nice to receive a
positive response within as short-a-time as possible, as the problem
giving rise to the request is often considered rather important to the
person making the request.
I hope this does not stir things up too much, a little patience all
round doesn't hurt.
