One unspoken connection maybe your culprit.  You would have take the
instrument cluster out and check it.  Check the surfaces of connections
where the long connector attaches at onto the instrument cluster.  I have
seen them heavily green with corrosion.  The 20 odd years of oxydation build
up has made it useless to deliver electricity.  It can affect any of the
lights or gauges on the cluster.  All the electricals are delivered through
that connection.
I have seen this a few times.

I would start by checking for voltage at the lLED. I know that the LED is
not likely to fail but it should be checked just the same.?If there is no
voltage at the LED then check the sending unit. There are very detailed
instructions on testing the system under the Dynamic oil pressure warning
system section of the Bentley.

85 vanagon  has no oil light at all even at key on.  Would a bad sender stop
the
light on check.
Too cold and wet here to mess with the sender now. Any suggestions
thanks
