We'll...my hunch was correct: dirty oil!  A combination of the extreme 
cold weather and my short commutes to work and back must turned the oil 
in my 90, which was 3400 miles old, into manure.  I have not heard even a 
peep from the motor since I changed the oil and filter.  I presume the 
sound was a cam bearing not getting enough lubrication during warm-up.   

I usually change both the oil and filter every 3000 miles, but the cold 
weather and my lack of free time lately took their toll...

Dirty oil could cause this reaction?? I must agree that my Coupe has only
been driven about 1,400 miles during the last 6 months (through the winter),
and also hasn't been on any long drives, but I'm running Mobil 1  5W-30 as
well. I change my oil and filter now every 2,000 to 3,000 miles (Please, no
comments on my being anal - I agree that I *am* about my cars!   :-))  )

The sound I heard is definitely something akin to belt squeal - probably the
cold weather combined with mechanics resisting startup - plus now your
ambient temperature is probably warmer...even in Binghampton...
