Decided to tackle my leaking low oil sensor. This thing has been a major leak for a decade.
I did replace the gasket with an LMR repop. When I removed the sensor recently, it had cracked.
So I ordered an OEM gasket. Part number E4AZ-6C646-B. Right away I notice that the raised ridge is a lot softer than the LRS repop.
But, i suspect the sensor is leaking internally, so I pull it apart. Fairly easy to do. Remove the clip, tap out the blue rubber insert, and then carefully pry up the retaining ring. Then pull out the sensor core with needle nose.

Just as I suspected, a lot of leaking oil past the seal, which is the black gasket. It was hardened. I thought the raised ridge was an o ring, so I tried to remove it and damaged it. So now it’s junk.
A repro is $100
So I ordered a 20mm x 1.5 drain plug off Amazon for $3. I’ll deal with it some other time.
