On a problem with oil pressure sensor leaking.
99% you need to replace the sensor with a new one.
Because if you can see the leak is not for the tread or gasket of the sensor.
If you can disconnect the the wire from the sensor.
and try to start you will see the leak coming from inside on the plastic, where the pins. of the sensor.

OK.. I hope this information work for you.

Thank you fo use fixya.

Oil gauge looses pressure at times. For 1989 Chevy 1500 pickup. What does this mean?

It could be the sending unit, or the engine could really be loosing oil pressure. Low oil pressure can be a number of things including a weak pump, blockage at the pickup screen, or worn bearings.

1993 chevy pickup z 71 driving down interstate and check gauge light came on and oil presure dropped to 0. Truck died and cant start again

It could be the oil pressure sending unit, or the engine could really have no oil pressure.
If the oil pressure dropped to zero at highway speed, I would expect the engine to lock up or at least make alot of noise.
You may have to tow it home and check the oil pressure with a mechanical gauge, or replace the sending unit to see if the gauge on the dash reads pressure.
The fuel pump gets power from the pump relay at startup, then runs off power from that oil sending unit when the engine is running.

89 Chevy S10 pickup. symptoms of needing oil pump or fuel filter? Oil pressure gauge jumps up and down, but also seems like its not getting enough fuel. Push the gas, barely any get up and go.

Replace the oil sending unit, this will take care of the jumping gauge. On the fuel, I would start with replacing the fuel filter, see if this helps. But my first guess on it would be the catalytic converter is clogged up.

I have a 1995 Chevy Lumina with the ''Low Oil'' light on.

may be the oil sending unit is bad
may be the oil pump
is there any noise in the engine?
have the oil pressure check at a repair shop to make sure you have enough oil pressure
if it's ok then have the shop replace the switch while they have the old one out to check the pressure

Oil sending unit


It's usually threaded into the bottom of the block near the oil filter, it should have a wire running from the top of it.
