If the pressure drops too much, an engine can be damaged beyond repair in a matter of minutes.
Why is the oil pressure warning light still on?
If you have refilled your engine oil with a new one but the light is still on, the culprit could be the engine pressure sensor. The sensor is connected through a circuit from the engine to the dashboard. With time the sensors get filled with dirt and this reduces their ability to detect low oil pressure effectively.
What causes an engine to lose oil pressure as it warms up?
The most likely cause of a car losing oil pressure when it warms up is a problem with the pressure relief valve, which regulates the oil pressure to ensure that there is enough pressure to circulate oil throughout the engine. When oil pressure is low, not enough oil is being distributed to the engine, potentially causing engine failure.
Is the oil pump OK when the engine is not hot?
And again, perfect pressure on idle at starting or short drives. I gotta think the oil pump is ok, due to the fact that idle pressure is fine when the engine/oil isn’t hot. Furthermore, the pressure is ok while driving when engine/oil is hot.
What does low or high oil pressure mean?
Oil pressure is determined by the rate at which oil flows through the internal combustion engine of a car. Low oil pressure is a real danger for engines, as it indicates that the bearings in an engine have worn, allowing the oil to flow more easily and at a lower pressure. However, high oil pressure is generally not a concern for motorists.

When does too much oil pressure become a problem?
Too much pressure is usually a problem only if the oil is too thick when the engine is cold or if the engine speed is very high. Most of the time, the relief valve will remain closed, but a burr or other damage to the valve or its bore may cause the valve to stick open.
What should the oil pressure be in a Vortec?
But after the engine warmed up, the oil pressure dropped below normal at idle and the engine noise (probably lifters) returned. Raising the engine speed to above 1000 rpm causes the oil pressure to increase to about 45 psi. If the engine speed is increased even more, oil pressure tops out at about 55 psi.
Can a failed O-ring cause low oil pressure?
But at idle, when oil flow is already pretty low, ingesting air via the failed O-ring could be enough to reduce oil pressure to a dangerous level. There’s a clever test you can conduct to determine whether the O-ring has failed and the oil pump is sucking air.
Low Oil Pressure Light On? The low oil pressure light is a warning that there’s not enough oil pressure or that the oil level is too low. This prevents the oil from going through the narrow passages to provide sufficient lubrication. Lack of lubrication can cause the engine to seize up or cause damage beyond repair.
Can low engine oil cause low oil pressure?
