Oil leak on my 97 Jeep

I was wondering if anyone may know what this oil leak is from on my 97 jeep grand Cherokee Laredo people are telling me the rear main seal but when they point the location out i do not see oil coming from there it comes right from the bolt area in the picture but maybe behind that pan it only leaks a very small amount like a drop and then thats it after driving around.

I cleaned the areas off and looked at the vavle cover as well and see no oil coming out anywhere. Can this be just old oil build up from a past leak in lines thats heating up and just coming off?

I need help on this I put a lot of money into the jeep now and had lots fixed even engine top end work done so just worried here.

The bolt on the left side of the oil pain looks wet. You could try re-torquing your oil pan bolts.. I have done that with mine, along with my tranny pan.

In the end, Minor leaks are very common with the inline 6 and not really much of a concern unless you are concerned with stains on your driveway. With that in mind, Jeeps don't leak, they mark their territory..

Thanks for the info but this not on the oil pan its across from the oil pan.The silver bolt that has oil streak running from it is the where oil is leaking.

The oil pan it self is sealed no leaks this is more so on the area of the rear main seal but that area is not leaking oil at all.

I'll try the bolt as I noticed its not in as much as the other bolt and see if this might help it.

If you have the 4.0 6 cylinder then it is most likely the oil filter adapter. The o-ring seals get old, hard and compressed an start weeping oil. Many write ups on replacing. Here's a link with some good information even though it is related to the XJ Cherokee.
Your '97 should use the T60 Torx but double check it. Also, the Mopar replacement o-rings are better quality than some of the aftermarket ones.
