Low Oil Pressure At Idle – Summary
In all, this concludes our look at low oil pressure at idle. If you notice that oil pressure light flashing at you, it’s an opportune moment to stop your car and consider your options. That warning light only flashes when the oil pressure drops below 5 to 10 psi, which is alarmingly low.
Why is my oil pressure low?
If your oil level is correct, and you are sure that the oil type is correct, the most common cause of low oil pressure is too much dirt in the pickup to the oil pump. Normally the oil pump takes the oil from the bottom of the oil pan from a pipe. Before that pipe, there is often a net that will prevent any big metal pieces from going through ...

How to restore oil pressure from bearing clearance?
SOLUTION: The way to restore oil pressure due to excessive bearing clearances is to reduce the clearances by replacing the bearings or installing a refurbished crankshaft/new bearings kit.
Why is my oil pressure low?
A clogged or damaged oil suction tube can cause low oil pressure because the oil flow is either restricted or leaking. You would need to check the inlet screen and remove any buildup that could be restricting oil flow.
What causes low oil pressure?
Faulty Oil Pump. Another common cause of low oil pressure is excessive clearances inside the oil pump. The exact specification may vary, but there is a general rule that the oil pumps should have less than 0.003 inches space between the gears and cover and 0.005 inches clearance between the teeth and pump hosing.
Why does my engine misfire?
A common cause of misfire can be oil in the spark plug and the oil could get there if there is an engine oil leak which will cause low oil pressure too. Fixing the oil leak will fix the oil pressure issue. This will return the engine to normal operating behavior and the misfire will stop.
What happens when oil bypass valves are activated?
When the oil bypass valves are activated, the oil pressure will drop. As I said before, the oil filter can get clogged to a point where no oil can pass through it. To prevent the critical blockage, oil filters have a pressure relief valve installed which has a main function to open if the pressure is very high (typically 5 to 40 psi). This allows the oil to bypass the filter and keep on flowing. But the engine oil pressure will be reduced to the capacity of the bypass valve.
