87.5 CGT noises

[Chris]

Whenever I start my 87.5 Coupe GT, just after I disengage the starter, it sounds as though
a high-pitched Donald Duck is caught in my engine some where.  It seems like a metallic
rattling or grinding.  It kind-of takes away from the pleasure of starting such an,
otherwise, nice-sounding engine.  The sound only lasts for a second or two, till the
engine settles down to idle.

Also, when I am driving along shifting gears, a little bumble-bee sounding buzz coming
from the instrument panel has started to sound in the last few weeks.  Most of the time it
is just for a fraction of a second.  In my '82 Coupe, I think I remember this happening
and the problem was oil pressure (I think).  However, in this coupe, I don't see the oil
light coming on.  The buzz seems to be happening mostly when the engine isn't quite warm
yet.

Lastly, the engine is strong (157,000 miles), but I think it's burning some oil.  I hadn't
notice this till I put in Castrol full synthetic last month.  Now it seems to be losing a
half-quart every two weeks.  I don't see any leaks.

Your help is much appreciated.  Please advise.
