Crankshaft position Sensor oil leak

[Texasknowhow]

Guys, the dealer is telling me they don't have and cannot get the oring seal that is on the Crankshaft Position Sensor (bottom front of the upper oil pan)! I've looked everywhere for this little odd looking oring (has a inner flange on it) and mine needs to be replaced bad.

Okay, so I went and got a 19mm X 2.5mm regular oring today at O’Reily’s. The 19mm measurement is the ID and it’s 2.5mm thick. It fit perfectly in the recess on the oil pan. I added a dab of axel grease to make it stick there and put the sensor back in. Torque the little nuts to 78 in lbs. and we’ll see…
