Does it do it at any temperature, or after the engine gets hot? What
viscosity oil are you using? You may also have a simple wiring problem.
The >2000 rpm buzzer switch is located just left of the oil pump. You
can almost see it under the water pump. Check the wire connection there
and at the two terminal connector near the t-stat housing. Make sure
there is no corrosion at these connections and that the connectors are
tight. They can look good but still make poor contact causing this
grief.

Subject: Oil pressure problems

Hey Folks
    I have a 90 Carat that I presume is having oil pressure problems. I
did
the 3000 mile oil change last week and after I cranked it and started to
press on the gas the oil light and buzzer came on. So I pulled over and
shut
it down, checked the oil and then cranked it back up. No buzzer until I
pressed on the gas. This went on for a few miles then the noise stopped.
After that it was quiet for 3 or 4 days then it happened again. Same
routine
did it for a little while then stopped again. It was quiet for a few
days and
then today did the same routine whilst on the way to work. It did not do
it
on my way home. The van uses no oil has approx 150,000 on engine. Never
had
oil problems before. Runs well. Has plenty of power.It's got me
concerned.
I'm anxiously waiting for the dash lights to come on telling me it's no
longer running. Anyone have any ideas or experiences with this kind of
event.
Any help will be much appreciated.
        Merv.
