What does low oil pressure on 2008 Chevy Impala 3.5 V6 LS


Do you mean what causes low oil pressure? This is a very reliable engine for the most part. If the oil light is on or gauge is reading low, have the oil pressure sensor inspected for failure. These sensors do go bad.

Oil light on after engine warm-up on idle


this means a mechanical gauge test is required to check actual pressure warm idling if low below 20 psi then the oil pressure pump relief is stuck open or engine bearing are worn

Low oil pressure


low oil pressure caused by worn engine bearings and faulty oil pump or oil pump pick up screen clogged with sludge.if oil pressure low engine will knock.check oil pressure oil pressure sending unit could be bad.

Low oil cause low oil pressure


No, the oil level nothing to do with the pressure.
If you have low pressure, check the sender unit, check the pressure with a mechanical gauge, if still low, check the pump

Low presure oil


first thing check is the engine oil level.if oil level okay check oil pressure should be for the 4.2 engine oil pressure should be 12 psi @ 1200 rpm for the 5.3 oil pressure should be 18 psi @ 2000 rpm if oil pressure good problem in the oil pressure sending unit. if oil pressure is low problem faulty oil pump or worn crankshaft bearings if oil pressure low engine will have rod knock.make sure you are using correct oil viscosity if oil too thick you will have low oil pressure oil too thin you will loose oil pressure.

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

What does a low oil pressure alarm mean


It means the sensor that detects your oil pressure has seen a situation where the oil pressure is too low and engine damage will result. Could be just a bad sensor, but better have it checked with a mechanical gauge to see exactly what the pressure is.

Low oil pressure light comes on and i changed the sensor


does the oil pressure gauge show low oil pressure?is it low oil pressure light? or low oil light? 2 sensors on this vehicle.make sure you get a chevrolet oil sensor,aftermarket sensor do not do well,make sure your using 5w30 or 10w30 wieght oil,if you are putting out over 20 lbs at idle in gear,i see no problem,should go up to 40 or better on accel,if it is low oil pressure and the gauge conferms,possible engine wear

Low oil pressure


If low oil pressure is verifiable the only repair is replacement of the oil pump assembly.

Start by verifying oil pressure with a mechanical oil pressure gauge. If oil pressure is low then replace oil pump.

I have low oil pressure in my 1994 chevrolet suburban


start by testing your oil pressure sensor, and then if not that drop your oil pan and the screen on your oil pump tube may be restricted. or change the oil pump could be weak
