There are a few things to cause the oil pressure to change.
The first, and easiest to check, is your oil filter. Some filters have a bypass valve, when did you last have engine serviced ?
Another part is the oil pressure sender itself. It may be shorting or going bad.
Please check those out and let me know.

Hi I'm having this message, 'low oil pressure' when temp go to suitable temperature my car Peugeot 407


The engine bearing clearances expand with heat which, if excessive, will lower the oil pressure. The spring in the pressure regulator in the oil pump will cause the pressure to drop for the same reason. A partially plugged oil intake screen will work in conjunction with the oil pump to cause it too.

Oil light is on car is full of oil engine is making taping noise is the oil pump gone bad on a 2000 crysler concord with a 3.2 engine


The oil light comes on when oil pressure falls below 7 pounds of pressure. A tapping noise from the engine is an indication of poor oil flow/pressure supply. You may have an oil pump failure or if high mileage, excessive bearing clearances that can cause oil pressure problems.

Fuel in oil pan


you need to check the fuel pressure and the pressure regulator. if these are allowing excess fuel pressure then this will happen. also if the fuel injectors are dirty it can cause excess fuel into the cylinders. this excess fuel will not be burnt and cause what is known as cylinder wash allowing the un-burnt fuel to leak into the oil pan. when you find the cause of the excess fuel repair. you need to change the oil and filter maybe more than once close together to rid the excess fuel in the oil.

High oil preasure


check the air vent at the top of the engine it may be blocked. and there is another one at the bottom will see it sticking out and go into the top of the engine. a flex rod should clean it out on the bottom one even an old bit of hose pipe pushed down the pipe should clean it out. then do a oil change and filter.

Engine stops suddenly


High oil levels cause the crankshaft to be submerged in the oil. This churns the oil up and causes frothing putting air in the oil and puts strain on the oil pump. Always keep the oil in the proper operating range.

The oil has been topped up in my renault laguna and is roughly an inch over the maximum line on the dip stick. i have been driving it and now my antipollution warning light has come on??


there are several reasons why you dont want excessive oil in the engine .. first if the level is high enough then the rods and crankshaft can dip into it .as they spin .. this whips the oil into a foam which is no longer a good lub .. the oil foam may get into the upper cylinders causing it to be burned which can contaminate the CAT converter .. it can foul plugs and in general damage the engine .. air contaminated oil does not lubracate or cool the rod bearings properly .. the air in the oil can "crack" (denaturize) under the pressure of the valve lifters, beaings and other places where high pressure exists .. this further damages the oil ... you definately dont want excessive oil ..

Oli leaking 1990 yj


Look for leaks high on the engine, like valve cover gaskets...

High oil pressure, if you actually had that, would not necessarily exit the engine....Crankcase pressures are not related to system pressure, per se.

Get a mirror and inspect very carefully.. Sometimes you have to clean the engine and test again, as air blows leaks all over (while driving...)

2000 jeep cherokee high oil pressure


Does it do this all the time or only when cold? (how cold is it?) If it only does this cold, it's normal as long as pressure does not go above that. If it also persists when at operating temp, change your oil filter and make sure it is the correct one. If due for an oil change, do it and add a good lubricating solvent such as Marvel oil, which will gently clean relief valve in pump and passageways. High oil pressure is actually a good thing but excessive pressure can cause the filter to explode or "blow" its seal. Then, you have more problems than anyone really needs!!!
Good luck!!

I hate be the bearer of bad news but it sounds like you bottom end bearings are getting worn out. You have excessive bearing clearances causing your drop in oil pressure.
