The sensor wire may have fallen off the motor, the sensor may have gone bad after all these years. Ground the wire to the car, if the lite goes out, the sensor is bad. Or reverse that, remove the wire and see if the lite goes out. Depends on how the car is wired.

SOURCE: 1989 Oldsmobile Cutlass Ciera leaks oil on back

that all depends on how high the leak comes from, it could be from the intake manifold gasket if its high up on the motor,, a little lower would be around the bearing seals , and lower yet could be the pan gaskets ,, keep in mind that a lot of wind is generated when the motor is running at high speed, and a leak from the front of the motor could be blown to the back very easily.

Oil light on and beeps has a quart low on it 2000 dodge caravan

3 possibilities. Bad oil sending unit. Bad crank bearings. So much sludge in the engine that the oil can't get back to the oil pan fast enough, this will cause bad crank bearings. I would pull a rocker arm cover first. If it is full of sludge, put it back on and drive it till it dies. save money for another car. If it is clean, replace the oil sending sensor.

Why does the oil warning light comes on after the oil was replaced?

Loss of oil pressure or faulty pressure switch knackered oil pump
Main thing don't run engine till you find out what caused the problem as the engine can tear its self apart if its a pump or flow problem

Oil light is still on.

The RX 8 engine burns oil pretty bad. Majority of time the oil light coming on is due to the oil level being just a little low. When the engine is cold check the oil level if its full then is another issue but if a little low just add a little oil at a time till full then light should stay off.

Oil light on when oil is full

a loose connection WILL NOT cause flickering oil light unless your your oil is empty at the same time a connector is loose. This flickering is most likely caused by clogged oil ports or failing oil pump. When this happens there is insufficient oil running through the engine, causing the sensor to activate the light intermittedly. Have this checked immediately to prevent extensive engine damage. Hopefully this helps!!

5W30...You mean the OIL LIGHT? Engine light is different that the oil light. The Ck Engine Light wont go on because oil is low. You cant drive the car with the oil light on, SEVERE ENGINE DAMAGE WILL RESULT.

Idiot oil light is ringing its bell non stop.... driving me crazy

The oil light is an indicator of oil pressure, not oil level. If it is chiming all the time now, it means that your engine likely has an oiling issue, such as a failing oil pump.

Get the vehicle checked out immediately before you cause irreversible damage that requires a replacement engine or an entirely new car.

Oil pressure

Could be the oil pump going bad. The oil sensor registers oil pressure, not oil level. If it isn't pumping oil, the light will come on.
