800 RPM should yield about 25-40 lbs. of oil pressure on a stock motor.
40 on idle up to 60 while on the move.
with your eyes
between 35/60 psi.
The gauge should be electrical.
You will have to remove the oil sending unit/switch and screew a oil pressure gauge into it's place and then start the engine and read the oil pressure.
Take the wire loose from the oil sending unit and then turn the key on and ground the wire to the engine somewhere and the gauge in the truck should go all the way past the highest point. If it don't then the gauge in the dash is bad are the wire going to it ( The 1 you grounded ) is broken. If the gauge is reading low oil pressure, Then unscreew the oil sending unit on the engine just behind the distributor, were you took the wire loose from. Then install a OIL PRESSURE GAUGE into it's place. Then start the engine and read the pressure, Now compare the reading on the dash gauge to what you are reading on the oil gauge.
Cold oil when you first start the engine will have lots of pressure then it will settle down as the oil warms and thins out.
Connect the wiring harness to the back of your oil pressure gauge. Secure the oil pressure gauge with the retaining screws.
It is necessary to read the density and the quality of the gauge. You should see the lower side.
The oil gauge shows the oil's temperature. The oil pressure gauge monitors the oil pressure for your viewing pleasure.
Defective gauge, defective oil pressure sending unit, low of oil, defective oil pump.
Yes you can. You will need a oil pressure gauge to do it. You will need to remove the oil sending unit that's back behind the distributor and screew the oil gauge line in it's place and then start the engine and read the gauge. You should have no less then 20LBS at an idle.
no if the oil pressure gauge light is on it means that your car dose not have the oil pressure needed to properly oil the moving components, if you are sure that this is not the problem then replace the sensor and the light should shut off.
If you already change the unit and it still the same then it can be the oil pump.
You will need to remove your oil pressure sending unit and install a mechanical gauge to get a true reading. You need to start out cold and write down the pressure reading and also once it warms up to operating temperature. If the pressure gauge is not the same as the mechanical one you have a bad pressure switch.
Six-year the oil pressure gauge for your 1999 Mitsubishi eclipse with the retaining screws. Connect the oil pressure gauge wiring harness.
Install a manual gauge to actually read oil pressure
"T" into the existing oil pressure gauge with brass pipe fittings. This way you will have the original oil pressure gauge and the mechanical oil pressure gauge. Don't forget to use thread sealer.
the oil pressure sending unit is designed to warn you of a low oil pressure. If the sensor goes bad then the low pressure light or gauge will read low when the oil pressure is actually ok.
i have a 1993 190E - my oil pressure gauge always sits on 3. ==New Answer Haedline == The oil pressure gauge actually moves but is related to several factors Engine Temprature Oil viscosity Engine speed. When you start you car the engine temperature is low the gauge goes to 3, after a long drive/travel and if your temp gets to 80C then with an engine speed of 750-800 RPM you oil pressure gauge will read about 1.5. if you rev. the engine the pressure gauge goes up to 3
Most oil pressure gauges operate by a varying voltage. The oil pressure changes the resistance in the oil sensor, causing the gauge to change readings.
Might be worn main and connecting rod bearings. Purchase a manual oil pressure gauge, and install the gauge where the oil pressure light is hooked into. Pressure should be between 40- 60 psi. If not, then you need to remove the oil pan, and hook up a pressure checker to the spot where you installed the manual pressure gauge, and pressurize the bearings, and see how the oil drips off of the bearings. Should just drip, if bearing is good.
Engine oil pressure will vary depending on if the vehicle is in an idle state or not. However, on average, it should be around 40, which is typically half of the gauge.
