Regulator and sensor are two separate pieces. What does your oil pressure gauge say at idle? And what was the TSB for excessive oil pressure talking about? On a Honda I had, the regulator seized up, so, full pump pressure was going to the filter. Somewhere in the neighborhood of 1800 PSI. It would turn the filter perfectly spherical, then blow the seams out. Never leaked around the gasket. (didn't have time, filter would explode within seconds of starting the motor.)

 

JRsick mentioned that he saw a TSB for the Oil Pressure Regulators.
But i cant find and dont know where too find the write up bulletin freeVersion.
I did not drive my grey goose today. Cant give and oil pressure at idle statement.
Thankyou for clarifying the 2 different parts sensor and regulator.
Maybe JRsick could show us where the TSB for the Oil Pressure Sensor is.
And ill call dealership parts folks.

 

I don't know that we've determined if you have an oil leak or high oil pressure. If it is a high oil pressure issue, then the pressure relief valve has been identified in attached TSB as a possible source. The PRV is a simple mechanical safety to divert oil back to the oil pan when the engine oil pump develops high pressure at higher RPMs. It's just a spring and a plunger. Not talking about sender or sensor. There may be leaks in these areas but leak is likely caused by high pressure.
TSBs are not recalls and dealer can choose not to fix for free. Recall info on your truck can be found at recalls.mopar.com, 800-853-1403.

 

Your oil pressure sensor is likely the component partially shown top center in your pic here. If you want to put the oil pressure question to rest, you can rent an oil pressure test gauge for free (when you return it), remove the sensor and thread in the gauge.
That said, your oil filter looks normal to me. Also, I wouldn't have sanded the gasket mating surface. You don't want to remove any surface material and create any low spots. Def no power tools. I usually use a rag soaked with brake clean to wipe it. That's it.



My cheap Harbor Freight test gauge.

 

Thankyou ALL. You guys are fantastic. I feally appreciate all the help and info.So yes absolutetly agree i shouldnt of put sandpaper too metal. Guess i was caught upIn the moment.

Onward so i should rent a oil pressure test kit. Unscrew remove the sensor just above the oilFilter Screw in pressure guage into the oil filter housing sensor port. Start my my engine ?
And record my oil pressure PSI numbers. Rite there at the filter port.
What should my numbers be ? 2005 ram 5.7 4x4 1500 SLT. ? 89100 miles.

Am i on track ?

 

Anything over 10 PSI at idle, and another 10PSI per 1000 RPM is considered 'acceptable'. I think anything over 80 is getting excessive.

 

In addition to heyyou's comments, you want to see that the pressure relief valve is working. Understand the the oil pump will produce double the pressure at 4000 rpm than it does at 2000 rpm. Problem is, the engine doesn't need the extra pressure, and high pressure will blow out plugs in the oil gallery. The pressure relief valve is sprung so that it relieves unnecessary pressure from the oil pump by diverting the oil (and pressure) into the oil pan.
You want to see if the PRV is working, or not. Check your pressure at idle, 1500 rpm, 2000 rpm. If pressure stays below 80 as heyyou mentions, then you can go to curb idle rpm. The FSM states curb idle (3000 rpm) oil pressure range is 35-105 psi.
If the PRV is stuck closed, you will see oil pressure rise linearly with rpm, as if the oil pressure needle is being moved directly by the throttle. There's some judgement here that is difficult to describe in a post.
Let us know what you find.

 

Okay so this is what i can do for now. Cant get ahold of a guage. So had to go with dashboardOil pressy guage. Let warm up for 5 minutes. Oil level is perfect.

With key in the ON position. Oil pressure needle Did not move but just enough to come up off the Resting spike maybe a 1/16 . Almost nothing.

Here we are at an even idle right after START.

Samething here but 30 seconds into an even idle.

And here we are at 2000 rpms even idle.

 

That looks fine. Right where it is supposed to be. Gotta be something else going on there. (Not a pressure regulator problem)

 

So the sensor doesn't need too be replaced ?
