presure!, low oil Options

[6gc_ct]

Getting disturbingly low oil pressure. brought the car to be diagnosed, one of my issues was that after driving for half hour maybe longer, at IDEL rpm only, the oil sensor light would come on sometimes just flicker. mech called me and told me that at 3k i was only pushing 15psi which is damn low. i dropped my oil pan yesterday to have a look see and everything looked ok. my bearings were tight, that and i never had any knocking noise while driving. my pick up screen was clean and clear. only thing i can think of would be oil pump but how could i tell without pulling it off?

I think toyota had an engineering defect in their engines(clog prone oil channels) starting around june 1996 and going on till about 2001. So you might also be running into this problem. Don't drive it warm while this is going on or you will wear your engine out fast!

If this doesn't apply to your car, I'd check compression on your cylinders. If it's still good, pull the oil pump and check for wear.
