1994 XJ 4.0 200k miles. Stock daily driver.
I do not have access to a mechanical oil pressure tester.
I'm not an experienced mechanic, so I don't know what to do next.
-
My oil pressure is not reading normally anymore. For the life of the vehicle, the gauge has read from 15 to 40 psi. Now, it never drops below 50, even at idle with a warm engine, and peaks at 60 when revving up.
Other than that, everything appears to be normal. The Jeep seems to drive the same, and the engine sounds fine.
I get the expected results when disconnecting and grounding the sensor wire.
I replaced the oil filter, and installed a new sending unit. Nothing changed. So I tried yet another new sending unit, still no change.
I have tested both new senders with an ohmmeter. The impedance still never drops below ~50 ohms.
-
Can anyone tell me where to go from here?
Could I actually be experiencing a problem in the lubrication system?
Is it possible that I may damage the engine if I keep driving?
