00 lincon navigator 5.4 oil pressure drop's low and light comes on , engine idles rough when pressure drops ,then pressure return s to normal range ,light goes out ,engine runs perfect. Is it my oil


Sounds more like an engine idle issue than a oil pressure issue. If the engine idle drops too low, the oil pump cannot provide sufficient oil pressure. If there is no oil light when the engine is idling normally, then there is no problem there.

I have a 2000 s80 t6 and the no oil pressure light comes on when the car is at an idle. Is it an oil pump problem?


Is the oil at the correct level when cold? If so, it could be the oil pressure sending unit or the oil pump itself. Have it checked as soon as possible. If there is a lack of oil pressure and you continue to drive it, you'll cause damage to the engine.

Oil light with a line underneathe it, what does the light indicate?


Low oil, bad sensor, really low idle.
First check oil level.
then if oil level is ok, and oil light is still there, pay attention to idle has to be 750 to 850 RPM.

If idle ok, give gas to increase idle to more than 2000 rpm if light goes away you need a sensor called OIL PRESSURE SWITCH.

My oil pressure light is coming on while the car is idling. when i give gas it goes away. what could the problem be? I have just had an oil change


Have the oil pressure sending unit checked to see if it is leaking,and the oil pressure checked to be sure the oil pressure is actually dropping.The oil sending unit could be bad,if not,rod,or main bearings could be worn,and causing the problem,make sure the correct weight oil is being used,then,you may have to go to a thicker weight oil,like 20w 50 and some lucas,if you do not wish to have the engine repaired.

Low oil pressure after engine warms up in 94 blazer with 4.3


I have a 99 blazer and ever since I have owned it, it reads lower in pressure when idling, but will go up too 40 while driving. This is normal for the vehicle. If the pressure gets real low, and stays low, it means its time for an oil change.

As long as the pressure goes up when you give it gas, it is fine.

Oil pressure guage pushes to 80 when not idling.


In an engine in good condition, oil pressure is a function of RPM. Higher rpm, higher pressure. Whne coasting downhill, in gear, the engine rpm will increase, hence, the oil pressure will go up, as required, and as expected.

There is nothing wrong with your engine, unless the oil pressure goes excessively high under any regime. Low oil pressure is a sign of low rpm, or under load, a sign of worn parts.

Have the idle air control valve checked, it might just need a cleaning, or a new one. Check all the vaccum hoses for leaks, all it takes is a pin hole to screw up the sensors.

When car is cold oil pressuer is at 75 lbs when car is warmed uped it drops to 40 lbs (v6 3800) when warmed uped and give it gas it goes up to 60 lbs but when i stop it dropes to 45 lbs why is this please...


When the oil is cold it is thinner or watery and the pump moves more oil as it turns making the pressure go up. As the oil warms up it thickens and the pump moves less oil letting the pressure go down. Increasing the engine speed makes the pump turn faster, therefore it moves more oil and the pressure goes up. Changing oil grades will change the numbers somewhat, for example 10W40 will give you different readings than 5W30. I don't see any problem with the readings you put in your posting. I wouldn't be concerned until the warm idle pressure gets down to about 30 or a little lower. Hope this helps.
