It means the oil pressure may be low, have a shop hook up a test gauge and verify your oil pressure is good and within factory specs, if not the oil pump may be defective, but that is only a guess. Do not drive this until you get it checked or you risk damage to the engine's bearings from low oil pressure if it is indeed really low and the sending unit for the light isn't defective..
Oil light should not come on unless the Level is LOW or the Oil Pressure has dropped below safe operating limits. I would do 3 things 1. Check Oil Level, if low, fill to the correct level and then restart. a. if the light does not go out.... 2. Pull the Oil Pressure Sending unit out and install a pressure gauge a. if the pressure is in normal operating limits, chances are the Oil Pressure sending unit is bad b. If the pressure is low, the issue is 1. Oil Pump 2. Engine Main or Rod bearings are bad and a engine rebuild is on its way
Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.
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
You need to determine if the engine has lost oil pressure (assuming the oil level is good) You need to place a mechanical gauge where the oil sending unit is that goes to your gauge. If this gauge reads low, you have an oil pump problem. Keep in mind that gauges and sending units can go bad. But the loosing power doesn't sound good. Start here to determine what is up.
the oil light generally means the oil pressure is low, most likely the sending unit is defective, but to be safe have the oil pressure tested with a mechanical test gauge, if it is low and u drive it this way you will ruin a $8,000 engine.
You need to install an oil pressure gage. If the pressure is good then check the wiring to the sending unit. It could be a bad sending unit but don't replace it until you test the oil pressure. If you don't want to add the gage inside the car you could install it under the hood or use a manifold gage, it's mechanical so oil flows right to the gage instead of a sending unit, you don't leave it on the engine. Mechanics use them to test engines and transmissions. You can buy either at a auto parts store. If you have low oil pressure then either the pump is bad, the oil pump pick up screen is clogged, or the engine is worn out (bearings, valve guides, piston rings).
I believe your sending unit is located on the top of the block, towards the fire wall. You can get an inexpensive pressure test gauge and put in place of your sending unit. It should be a 1/4" NPT fitting. Does the pressure gauge fluctuate between low and high RPM? If so, chances are that your oil pump may need to be replaced.
