1990 Tbi 350.
I experienced low oil pressure for ab0ut 30 minutes while driving. it dropped from the normal 30-40, to the first hash mark on the half moon gauge which seems to be about 15.
At first I stopped, turned the truck off then on and the pressure returned to the normal 30 at idle for a while.
But about 15 minutes later it dropped to 15 again. 20 minutes later on the freeway, it just jumped from 15 to 30 and stayed there.
Took it to for an oil change the next day, and it stayed normal. (It went up a few psi.)
Any thoughts? Is it possible the filter was blocked?
What are the symptoms of an oil pump going bad?
Thanks.
