A common problem has been that the 'L' shaped oil circuit board and
buzzer unit goes bad.  It's not too hard to get at, but it is
behind the speedometer and requires removal of the instrument cluster
and a partial dissassembly.  There are instructions on how to do it
on my gauge faces page at http://da-studios.freeyellow.com.

Here's something else you can try...ground both (or one at a time)
of the wires running to the senders. This will give the oil pressure
circuit a constant 'good' reading.  If it still buzzes, you know it's
more likely the circuit board or the wiring somewhere between.
