What causes no oil pressure at startup?
Common causes for low oil pressure are: dried/cracked O-rings in oil sump, worn main bearings, sticking pressure relief valve in oil pump. If you drop the pan for a new set of O-rings, you can also push the crankshaft and see if it has any play (that indicates bearings wear).
What damage can low oil pressure cause?
When engine oil pressure drops, friction between different parts increases. This results in a steep decline in engine performance. Watch out for common signs of decreased engine performance such as a reduction in fuel economy, loss of power, and engine stalling.
What happens if you have no oil pressure?
Engine Overheating
Without sufficient oil pressure, your car’s engine will operate with decreased lubrication and increased friction resulting in more heat. Engine overheating can be a complex issue. While it doesn’t always mean low engine oil pressure, low engine oil pressure can lead to an overheating engine.
What causes low oil pressure after oil change?
Not changing the oil at the due time and poor maintenance may lead to sludge buildup in the engine. It will not wash out even if you just change the fuel. The deposit deprives the sensitive engine parts of normal oil pressure. As a result, you see the oil pressure light on after oil change.
