If cleaning the engine does not work, replace the oil press. sending unit. These senders on Jeeps have had a history of problems where they will work one day and not the next day.

Hi there;

Your looking foer the oil pressure sensor on the 2004 8.1L.
You will find it located directly behind the EGR valve threaded into the block just to the drivers side of the center bolt for the transmission to block connection.

SOURCE: Where is the oil pressure sensor located on a 2003

It is on the top backside of the engine block, behind the intake manifold mounted into the top of the block. You will have to lean up over the engine to see it.

What does a oil pressure relief valve do

For any engine with an oil pump, the components inside it are designed and engineered to operate at a certain range of oil pressures.
For example, an automobile engine might be designed to operate at # 30 to # 70 pounds of pressure.
If you subjected the bearings to double the pressure, you could achieve bearing failure, as you could with not enough pressure.
The oil pressure relief valve will "open" when the upper limit of pressure is reached and allow the extra pressure and oil to go straight back to the crankcase.

Can anybody pls help me with a oil pressure release valve I tried every place and does it come in a kit

What is an oil pressure release valve? Never heard of one. Do you mean oil pressure relief valve? Depending on car, some are inside oil pump, some are in oil filter adapter. Try calling it a relief valve and see if parts store can now help.

Have 1986 Chevy K-30 with a 454. Oil pressure is running about 70lbs. Is that to high&could it be the oil pressure relief valve&where is said valve. Thanks

I don't believe there is a oil pressure relief valve, but there is a pressure bypass located in the neck of the oi filter mount. I would check to make sure that you have the correct oil filter on the motor.

Does the 6.6 duramax diesel engine have a pressure relief valve that regulates the oil pressure?

it should have. It will be either part of the oil pump or a relief valve screwed into the oil galley or oil filter housing above the filter body.

Hi I'm Peter, Check your oil pressure some pumps as they start to go out the oil pressure will fluctuate. I would also check the oil filter housing and or pump for a pressure relief valve. if the oil filter becomes clogged there is usually a relief valve in the oil filter housing where it mounts to the engine then into the pump that if the filter collapses or becomes clogged it will open. Sometimes the spring behind the steel ball will weaken or break causing the ball to chatter back and forth. You can use a mechanics stethoscope to narrow it down further if you need. If it is your oil pump going out you will need to do something soon or you will have an engine rebuild on your hands.

1990 triton oil pressure relief valve location

Hi Lee, There are two oil pressure relief valves on most vehicles. One is fitted onto the oil pump assembly and another onto the oil filter housing assembly. The oil pump pressure relief valve is located at the front of the engine and is accessed via a blind nut on the side of the unit. The bolt is in the form of a cap, which when removed can be seen to be holding down under tension a spring, which in turn presses the valve. If the pressure becomes too high the valve body is pushed upwards and releases an amount of oil, thereby maintaining the required pressure. The valve built into the oil filter housing works in much the same way, but its job is to allow oil circulation in the event of a blocked oil filter. regards John
