[T3] Odd Whirring Noise


I have started hearing an odd whirring noise coming from my 66 Squares 
engine.  It sounds like a transmission turning through frozen gear oil on a 
-20F day.  Yeah, I know the SoCal folks will have no idea what I am talking 
about. 8^)  Anyway, it is dependent on engine RPM, but not vehicle speed. It 
does not change with engaging or releasing the clutch.  I have not been able 
to isolate it yet.

However, in the process I discovered something that I am not sure about.  
Both my RED and GREEN lights come on when the key is turned on.  They both go 
out once the car is started.  This sounds correct to me.  But I removed the 
wire leading to the oil pressure sensor with the engine running and the green 
light does not come on!  I am guessing the sensor is bad, but why does the 
light go out once the car is started?  Are the sensors 6V/12V specific or can 
I try the one from my 71 Fasty?  What else should I be looking for?  There is 
plenty of oil on the car.  What are possible sources for the whirring sound?

Thanks in advance,
