    Im not really sure what is wrong with my car. I am not at all mechanical. When I start my car it starts to leak oil out of the drivers side of the engine. Where it is leaking looks to be from a connection on the drivers side of the engine where a wire in a black tubing connects to the engine? Like I said, I am not mechanical at all. If anyone knows anything about what this may be, let me know... prix_white@yahoo.com

I believe what you're looking for may be called an oil pressure switch or oil pressure sensor instead of an oil sensor. If this is correct it should be easy to locate at almost any local auto parts supplier or online at places such a www.rockauto.com. Rock Auto has an easily searched catalog and the prices seem reasonable. Also there are pictures of the part.

If what was removed is an oil pressure unit and the engine is started oil will definitely be pumped out of the engine. I hope this is of some assistance.

Would a bad oil pressure switch cause a no start on a 98 b2500


Hi,
Symptoms of a bad or failing Engine Oil Pressure Sensor
  • Oil Pressure Light comes on, and you check the engine oil level, But oil level is okay, you can blame the false reading on the sensor.
  • Oil Pressure Light blinking constantly. This is the normal >check< oil pressure sensor Warning that the sensor is going out.
  • If the sensor is giving false readings, Dispite oil level, the sensor could be replaced.
If the Sensor is currently not working, and does not warn you of engine oil level, and oil level gets extremely low, The Engine could burn up/stall due to lack of oil, and may not restart.
Then you could probably blame it on the sensor.
But really would be lack of oil.

Intermittent No Start,
Common causes deal with 3 basic systems/areas of engin
  1. Compression, its the build up of air and fuel into the engines cylinders. Then is compressed by the pistons. And is under pressure. FAILURE An Air leak (vacumm leak) will allow pressure to escape.
  2. Ignition System, good battery, good relays, wires are not loose or disconnected, good 10volts to starter, 10volts to distributer>gives 20kvolts to spark plugs>has strong spark to ignite compressed air in cylinders. Other sensors need to work. Crankshaft sensor(ccs) Throttle Position Sensor(TPS), +more
  3. Air/fuel Ratio, Air Intake Manifold, and Fuel Pressure Sensor *Fuel Injection Pressure Sensor---if car is fuel injected*, air filter is clean and intake manifold hose, Throttle Plate Acuater, Idle Air Contro Valve(IAC). Also vacumm leak cause no start. To much air not enough fuel will cause lean fuel mixter==low power, low idle, no start.......To much fuel not enough air will cause rich fuel mixter==too much fuel could cause engine knock, flooding of engine wet spark plugs, No Start
Scan Vehicle computer for Codes, Places like AutoZone---Discount AutoParts will connect scanner for free, And Code Will say What is wrong with Vehicle,

2001 jeep grand cherokee laredo overheating


There is a good chance the head gasket is leaking.
If the air flow thru the radiator is good, and the coolant flow is good, there could be something like an exhaust restriction that is causing extra heat, or the head gasket may be leaking.
Will it get hot just sitting still, or do you have to be driving it ?

At idle the oil pressure light comes on


i would say the car is safe to drive.IF the pressure sensor was working correctly, and your engine was a complete dog, then you would expect there to be some loss of oil pressure, but not 0 to 4bar in a blip of the throttle.given that the oil pressure sensor is a common fault (and it controlls the oil pressure light, it is not a seperate switch), i would say the sensor has a 'dead' spot on it, and a blip of the throttle just sees it outside the dead zone of its reading, and pings back to 4bar (its natural to get a slight rise in oil pressure when higher revs are acheived). 4bar is the right value, its what mine sits at. maybe a tiny bit under (3.95) when the engine is very hot/in traffic the oil pressure is reading just over 4 at all times, dosent go up or when accelerate or down at idle is this normal, used to mercedes W124 where it can register .3 up on idle but when accelerate it should goto max, ie 3 bar Whats the mileage on the car. Sounds like It certainly is suffering from low oil pressure at tickover, but loads of cars do and continue running for thousands of miles. blue/white smoke on start up and that points to valve seals and, yes, the head would have to come off to replace them, but it's normally just blue smoke. White smoke points more to head gasket, but that would be replaced anyway when doing the valves.Bet the engine sounds smooth as silk too
Oil pressure is determined by the rate at which oil flows through the internal combustion engine of a car. Low oil pressure is a real danger for engines, as it indicates that the bearings in an engine have worn, allowing the oil to flow more easily and at a lower pressure. However, high oil pressure is generally not a concern for motorists. Oil pressure fluctuates with the heat of a machine, and though high oil pressure can indicate a serious problem, it generally means the engine is in an adjustment period.Oil Pressure at Idle For many cars, oil pressure is much higher upon start-up or while idling. The reason for this has to do with the temperature of the engine. When an engine has been sitting turned off, it cools down, as does the oil that flows through the machine. Upon start-up, the engine temperature begins to rise. As it rises, so to must the oil heat up to find a level pressure to flow through the machine. Cooled oil is thicker, causing it to flow more slowly and at a higher pressure through the machine, until it reaches its optimal operating temperature.Pressure Relief Valve Recurrent high oil pressure, even after the machine has been running for a while, can indicate a problem with the pressure relief valve. The pressure relief valve is responsible for regulating oil pressure throughout the internal combustion engine. It is a safety device intended to keep vessels or piping from experiencing extreme pressure. When this device is malfunctioning, it will cause high oil pressure in an automobile.Types of Oil The type of oil put into an engine can also account for extremes in oil pressure. Low-weight or thin oils will operate with low oil pressure, as they will pass through the machine quite easily. Thicker oil will pass through the machine at higher oil pressure readings. Generally, after an oil change, when fresh oil is introduced into the machine, oil pressure will increase. This, however, is only a sign that the oil that formerly operated your car was too thin for optimal performance.

Sounds like you have a faulty head gasket or maybe a cracked head.This can cause overheating and the check engine light to come on.The code for the o2 sensor is probably caused by coolant getting into the exhaust system and coating the sensor.The coolant fan may work but it cannot remove enough heat from the rad to make the engine cool off.Try some engine coolant stop leak to see if it will help.This maybe only a temperary fix.Let me know if you need more.MOE

Sounds like a blown cylinder head gasket between the water and oil passages and galleries. Is the amount of oil significant..not just a hint of a film? Do you have any sign of creamy looking 'mayonnaise' on the under side of the oil filler cap and entrance? This would be sign of the reverse i.e. that water had got into the oil. The oil in the engine is driven around the galleries under pressure, certainly more pressure than the coolant, so if there is a connecting leak oil will be forced through it into the coolant. The best way to make sure is to have your coolant system pressure checked by you local garage when the engine is really cold. With the engine off and the oil filler cap removed a leak will be indicated by the coolant pressure dropping slowly (as water is forced through the leak back into the oil system). Also monitoring the pressure of the coolant when the engine is started from cold will also reveal a leak. The coolant is at normal atmospheric pressure when cold and only when the engine gets hot does the pressure within the coolant system rise (somewhere between 7 - 10psi depending on power unit). However if there is a leak the pressure of the coolant will rise rapidly as the oil system reaches pressure quickly, in other words the coolant system will be forced to the same pressure as the oil system through the leak. The remedy is to renew the head gasket.

Unsteady oil pressure.... oil pressure so low and the car will start, my question is, the gauge reads about half between (low) and (Normal) bar, while in neutral revving the gas the needle will gradually...


If you use the wrong weight oil this could be a big factor 5w 30 I believe is the right weight to use.the valve cover is leaking on the plugs.The fuel pump can cut off if the oil sending unit does not read enough pressure.If the oil change had the right weight oil ,then change the oil sending unit.

Flucuating oil pressure guage


it is normal for you oil pressure to to rise and fall
base on how you are driving ,if your sitting at idle your pressure will be lower that if you driving at 50 or 60 mph.

Oil pressure fine when i start car. when you drive for a little the pressure will drop and rise any solutions.


Depending on the range of rise and fall, this is completely normal. Oil thins out as it gets hot so you will notice the pressure drop significantly at hot idle. A typical value would be 20psi, then as the engine revs up, the pump creates more pressure because it can now keep up with and exceed the leak-down or bleed-off from the bearings. The maximum pressure would be limited by the relief valve in the oil pump which could typically be as high as 60psi.
