Unfortunately, there are plenty of people running around who give out free advice and often it's worth exactly what you pay for it. MOST of the time when the oil pressure is low there is nothing wrong with the sender OR the oil pump, but many people who don't understand what's going on inside the engine make all kinds of nonsensical assumptions.
I'll give you a brief description to help you understand what's going on inside your engine. The oil pump intake tube has a screen over it and the inlet is down, near the bottom of the oil pan. The screen keeps the big chunks out in the event that something terrible happens and there are big chunks of something floating around. The screen doesn't really protect you from much except those big chunks.
The pump pressurizes the oil and pumps it as fast as it can, depending on how fast the engine is running. When the engine is running fast, lots of oil gets pumped, when it's running slow, only a little oil gets pumped. The pump doesn't have anything more to do with pressure, since it just pumps as much as it can. There IS, however, a spring loaded piston that sits in one of the oil journals (that's a tube through the engine casting). When the oil pressure exceeds a specific amount the piston is pushed up, out of the way, and oil leaks past and back into the crankcase. As the pressure starts to drop, the piston closes back over the hole. The idea is to keep the pressure at a relative constant.
Where, you might ask, does the pressurized oil GO? That's the part that's important to the engine. Pressurized oil is forced into the space between the crankshaft and the bearing surface. In a perfect world, the crankshaft main bearings and the rod bearings never actually touch the crankshaft. In that perfect world, the pressurized oil forms a thin film around the bearing and in that perfect world the bearing would never wear out since it never touches metal.
In the REAL world, things are a little different. Every time you turn off the engine, the oil leaks past the bearings. Every time you change the oil the oil drains from the oil pump pickup tube. When you start the engine without that pressurized oil pushing through the oil pump, the bearings come in contact with the crankshaft. Engineers have made certain that the crankshaft is smooth and if everything is working properly there is still a little oil on the bearing surfaces from last time the engine was run, But having oil THERE is different from having PRESSURIZED oil THERE. While the pressurized oil keeps the bearing surface from touching down on the crankshaft, left-over oil just acts like a nice lubricant and keeps the bearing from wearing out completely next time you start up and before the engine builds oil pressure again.
Over years and many times of starting the engine, the bearing surfaces wear and more oil starts to leak past the bearings. Eventually, oil starts to leak fast enough that the oil pump can't keep up, and the oil pressure starts to drop because of all of the volume of oil that's leaking past. Remember that the oil pump pushes more oil through when the engine is running faster, so you'll get good oil pressure when you're going down the road, but at an idle the pressure will drop.
That's the bad news. The good news is, if you're still able to maintain oil pressure when the engine is running at highway speed, you can probably get the oil pressure to stay up a little higher at an idle too.
That's what higher viscosity oils are for. New engines are recommended to use low viscosity oils. If you look in the manual you'll see that your engine was supposed to have a light weight (probably 5W15 viscosity) oil when the engine was new. Now it's a little older. To bring the oil pressure up to a safe level, change to a 10W30 or even 15W40.
The thicker oil will not be able to leak past the worn bearings as fast. That will allow the oil pump to keep up with the rate that the oil is leaking out.
Understand that if the oil pump is able to create oil pressure at highway speed and while the oil is cool, there is nothing wrong with the oil pump... also, there is nothing wrong with the oil pressure sender unit either. Change the oil to something with a higher number and the problem should be solved.
That was probably more than you wanted to know.
The first thing you really need to do is have the oil pressure tested with a gauge rather than guess at it being a oil pressure sender or not. Low pressure can be caused by excessive wear in the engine bearings or the oil pump itself. When the engine is at idle is of course when your oil pressure is going to be at its lowest point. As the RPMs increase so does the rotation of the gears inside the oil pump therefore increasing the pressure and the sending unit turns the light off. Again, have the oil pressure tested with a mechanical gauge. Low oil pressure will cause severe engine damage.
You probably have a stuffed oil pump or possibly a crook oil pressure sender. when it comes to oil pressure always start of by thinking the worst stop driving until you KNOW what the problem is.
alot has changed over the years in clture but nothing has changed hen it comes todrugs people ehtink it is cool and pressure other teens and even younger kids to start.
It is a pressure which comes from the front
Warm oil is alot thinner than cold oil. If the light doesn't come on until the car is warm it means the pressure is less with the thinner oil.Make sure the sender is accurate,then look into causes of low pressure, (bad pump,worn bearings)
I also have a 2000 eclipse and the low oil light comes on at low idle,first I double checked my oil level and condition,ok, then light still on,I did replaced the oil sender which from autozone $20.light changed to on all the time,I checked with friend of mine who own a shop in sf and he recom replace the oil aftermarket. the low oil light comes on again after drive for about 5 miles,my friend try to replace the engine for me.help.
it comes from air
u dont have enough oil pressure. u need at least 30-60 pounds and ur knock is your crank and rod bearing failing along with your valves
Oil pump needs replaced,engine light comes on because of low oil preasure.I just changed mine out and it took care of the problem.
Diagnosis .... If water pressure is good everywhere else, and the recent pressure seems to have changed, probably cleaning your shower head filters. If never had good pressure but do everywhere else, you may need a lees restrictive head or shower valve, or your piping may be corroded. Pressure is not the same as volume.... Most people say pressure when they want volume. You can have the same pressure to take a shower that comes out of a squirt gun, or one that comes out of a fire hose... The difference is the volume of water that makes the biggest difference. The answers above are mostly volume related.
If a will has "come out of probate" then the testator must have died and the will was allowed. It cannot be changed.
i think the tank is behind the seat. look on top of the tank and see where the fuel line comes out. remove the assembly and the sender comes out with it.
An ambient pressure is a pressure on the surrounding medium on an object, such as a gas or liquid, which comes into contact with the object.
The compressor needs to be changed. There is no more pressure in it. It keeps working but only hot air is comes out.
It depends on what restrictions the sender placed on the package. If the sender has the package "drop shipped" the driver will leave the package at the door without a signature. If the sender requires a signature, then some one has to sign for the package. However, the package comes and no one is home to sign for it, they do leave an information sheet and a place to sign for the package for a future delivery the next business day.
Yes peer pressure does more harm. what good comes out of it? peer pressure persuades you into , Drugs,Alcohol,Smoking and many more what good comes ou of that
Downward or inward if the pressure comes from being submerged in a fluid.
normal blood pressure reading
It is changed by the vapor that comes from the clouds.
Are you saying there is enough oil in motor? If so could be low oil pressure and or bad sender, how many miles? how hot was it when oil light came on? If it does it only HOT and at idle that is kinda of normal as it means low oil pressure at idle, Porsche talks about that in their owners manual say back in the 80;s SC's and 911's
Its not a force but the answer is pressure. PRESSURE. (:
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
The temperature effects the pressure of gas in different ways. The hotter it is the more gas comes under pressure.
