The Oil Pressure Sending unit...What is it exactly? What breaks? The unit itself or some more o-rings? If it is not too expensive I might as well switch it out too...

I used a thicker oil cause my 00 4.0 the rear main seal is leaking. I think they are all one piece. You can add the lucas or some other product to try and stop it for a little or slow it down.

Looks like this but is screwed into the block and has a connector going on it. The diaphram inside fails and oil is pushed through it. No o-rings, just replacement.

So yesterday I went to the the dealer to get the "3 piece o-ring" kit and apparently the WJ (1999-2004) Jeep does not have use this anymore. I asked to see the oil pressure sender too and it did not have an o-ring on it either so I have ruled these two things out. I changed the oil and once again it seems to be coming from above the filter area. The seal around the oil filter is fine and dry....It might be the valve cover gaskets. I will try this next weekend.

Thanks Two speed. Okay I just read your diaphragm failure post. I saw it above the filter. It was $54 at the dealer. I asked to see it but since it didn't have an o-ring on it I figured it was not the problem. I guess I can switch this out before I change out the valve cover gaskets. I hope it works.

If you change the sending unit, clean the connector with some electrical connection cleaner before you re-connect it. Otherwise you may get some funky oil pressure readings due to a bad connection.
