Minimum oil pressure for a hot engine per the factory shop manual for the 1989 is
1000 rpm 6 psi
2000 rpm 18 psi
4000 rpm 24 psi
I'd say your good to go, although the gauge reading could be wrong, could be high, could be low.
If your happy with everything else with the car, I'd try and talk the owner down in price (negotiate) and then make the purchase.

yes it could be a clogged pickup screen. This I know. The next question would be what is clogging the screen ? Maybe an oil change could shed some light on the situation. Also cutting apart the old oil filter and inspecting the element can be informative.
yes i know that's some work and expense on a car someone else owns, but it could help you make your decision.
one final thought, the engine is full of oil ?

Good feedback, thanks! I think I'm going to pass on this car. You're right, there are many to choose from. Also, at this time of year I think the sellers must be motivated or they would probably wait til spring to list their cars.
