leak around oil level sensor

5.2; Leaking around the oil sensor (level sensor) mounted on the side of the oil pan. From the Consumer guide this is apparently a common problem on earlier 5.2 where the oil leaks around the sensor and wall of the pan. I am not due for another oil change for 3000miles so I donít want to take it apart now but will do that later at the next change. I was wondering where the leak is and if I can just tighten the sensor to stop the leak. Is there o-ring that needs replacing or do I need to replace the whole unit? I think I am loosing about few drops a day so it doesnít require immediate attention, but I would like to prepare for permanent fix. Thanks for you input.

Hi I know this was a while ago but how did you fix it? I noticed my 93 ZJ is doing the same thing.

Thanks guys. I dont think that will work, it looks like a banjo bolt gasket. This sensor is about 1-1/4" or 1-1/2" in size. I think the only way to fix is to change the whole sensor. I might try to tighten it but afraid it might turn from a seep to a leak!

I wouldn't use Teflon tape just because bits of tape may break off into the oil passages. A little bit of thread sealer paste would work though.

Has anyone removed the sensor and plugged the hole? If so what did you use?
