Why does the oil light come on intermittently?
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 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 to do when your oil light comes on?
That is why you have good oil pressure going down the road and low pressure when the engine is idling. The oil pan is not hard to remove and the pickup screen is around 18 bucks. Make sure to use locktite on the bolts holding it on. Good luck
When to turn off the oil in your car?
When it does, it is usually when at the idle level. Usually. That time last week, the threshold for turning back off was up closer to 900-1,000 RPM. You have reached 220000 miles so engine wear is not unusual. You could just use a high mileage oil a little heavier than what you use now and watch the oil level.

What should you do if your oil pressure is low?
In case your vehicle is only equipped with a warning light, then it should never come on while the engine is running. If the gauge drops into the red or the warning light stays on, stop driving immediately and shut the engine down. Insufficient oil pressure will quickly lead to expensive engine damage.
Why is my oil pressure light not working?
When the instrument cluster can’t feel the signal from the oil pressure sensor because of a broken wire or bad connection – it will light up the oil pressure light. Check the connector at the oil pressure sensor for any corrosion signs and make sure that the wires look good.
What should I do if my oil light is blinking?
What I would do is with the engine idling, wiggle the wire plug at the oil pressure switch and see if the light does flicker off and on, so you may need a helper. Then next if it does not is to check the actual oil pressure with a gauge and see if the pressure is truly fluctuating. If so, the problem is most likely with the oil pump.
What does it mean when your oil light goes off in your car?
If the oil light stays off, it means your engine was low on oil. You will need to assess where the oil went, but can safely drive the vehicle as long as the oil doesn’t leak out of the engine too quickly. If the oil light comes back on, shut the engine back down.
What causes the oil light to turn on?
4 Reasons Your Car’s Oil Light is On: Low Oil Pressure. This means the oil pump isn’t circulating enough oil, or the oil level is too low for the system to circulate. Old Oil Circuit. Over time, the oil circuit may begin to wear out. Regular Oil Change. Your car’s oil should be replaced at regular intervals according to the vehicle owner’s manual. Faulty Oil Sensor.
Why does oil light come on at idle?
Sometimes when an engine is just slightly low, the oil light may come on at idle simply due to the lack of oil pressure when the motor is not working as hard.
Why does my oil light come on and off?
The oil light may come on for several different reasons, including a low oil level or a faulty sensor . If the oil light illuminates while you’re driving, you should immediately pull over and turn off the vehicle. Your engine may stop and refuse to turn over if you have run out of oil.
What can cause oil light to flicker?
Low oil pressure or loss of oil pressure can be caused by a low oil level in the crankcase , a worn or damaged oil pump, or worn engine bearings. In older high mileage vehicles, it is not uncommon to see the oil warning light flicker at idle because of internal engine wear.
How often does oil pressure light come on?
Most of the time, it does not come on at all. Yesterday, for a short while (one 15 minute trip), the threshold seemed to be closer to 1,000 RPM. But, after that, it never came on again for that day.
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?
