Wj 2001 Jeep Grand Cherokee V8 oil leak

Hello everyone! I am new to the forum and I apologize if I placed this in the wrong section... looks like the proper one though

2001 Jeep Grand Cherokee Limited 4.7L V8 is leaking oil just above the oil filter. Is it possible that it's the oil pressure sending unit? If not, what else could it be?

Its definitly possible.Mine leaked oil from there,but not really on the floor,more inside the plug area of the sending unit.But its most likely that.

Mine leaked from the oil filter... Twas the oil filter

edit, noticed you said it was ABOVE the oil filter. probably oil pressure sending unit.

I need to check mine. I have had to add oil since I bought it a month ago and I don't seem to be burning oil. I have to many oil spots in my driveway to notice new ones.

Mine does it, seems a pretty common fault. Got a replacement sensor but looks a hassle to fit due to location.

Oil pressure sensor is most likely the culprit..... Changed the oil twice one day because I thought I had a faulty oil filter.... Needless to say it wasn't the filter leaking, and my OPG ended up acting all crazy... Needle floated all over the place.

My needle is fine and then just randomly drops and reads that there is no pressure. I found a video on how to replace it, looks pretty easy. Thanks everyone!

It is easy,just make sure you slide the red clip to unlock the plug before you pull it out.

My friend emailed it to me and now I can't seem to find it. I can post pics of how to find/remove it. Only took me an extra 5 minutes on top of my oil change. Oh and sorry for not responding sooner. School is keeping me very busy

Mine does it too. I'm changing the unit when I'll be changing the oil, because it seems to be a lot more accessible when the oil filter isn't mounted.

I carefully put teflon dope,not tape, on the threads,carefully without getting any in the engine block,and not to much to make it run,and i have no oil dripping anymore.Let it set for 30 minutes before running the Jeep.
