Why does the oil light come on intermittently?
If the head was legitimately cracked, or even a head gasket problem existed, then it’s possible the engine oil was diluted with coolant. Once this happens it will wash out crankshaft bearings and lead to oil oil pressure. You state the oil pressure is good.
Why does the oil pressure light come on when there is no oil in the engine?
Low Engine Oil Level To create an oil pressure in the engine, the engine needs to pressurize oil. If there is no oil to pressurize, it will be impossible for the oil pump to properly do its job. If your oil pressure light comes on and sometimes disappears, especially when you turn the car, a low engine oil level may cause it.

What to do about intermittent oil light on Ford Escape?
If you went with a thicker oil, it wouldn’t flow through the bearings as fast and the pressure would be higher. Slip it into neutral to raise the RPM’s until you get it changed. You could try some STP or Lucas oil treatments which generally increase the viscosity. 16 people found this helpful.
Why does the low oil light come on?
If the Low Oil Light comes on, but you check the oil in the engine and it’s at a good level, then a faulty oil pressure sensor may be to blame. When this sensor goes bad, it will start to give inaccurate readings. After the readings fall out of specification, a warning light is set.

When to check the oil pressure at idle?
Check the oil pressure again. Only this time let the engine idle until it comes up to full operating temperature while watching the pressure gauge. See what the oil pressure reads then. When you checked your oil pressure, did you check it at full operating temperature at idle?
When does the second oil light come on?
