Question Sahara 4.0 Oil filter Adapter o-rings

Please bear with me I am new at posting to forums, I changed my rear seal and oil pan gasket now I need to change the Oil Filter Adapter o ring trio (trifecta as I heard it called affectionately) however I find a lot of information on Cherokee's but this is a 1999 Wrangler TJ with a 4.0. Does anyone have any tips or pictures showing tool used? The reason I ask is I hear pipe wrenches and12mm wrenches and Torx60. I dont want to strip anything in the process. Any help would be appreciated.

There is no adapter on a TJ 4.0L. The filter screws right onto the block.

What Patrick says. Why do you feel as though you need to change the filter 'adapter'? It has nothing to do relative to the oil pan, as it is mounted to the block

I wish that was true, but in this case it has an adapter. The filter screws in from back to front.

If you have a Cherokee engine in your TJ, you do not need the adapter. (Unless there is more to the story that has not been disclosed.) Just relocate the filter nipple from the adapter to the block and rid yourself of the problem. Depending on year model, the adapters had either a hex head bolt, a socket head bolt or a T-60 Torx bolt. In a TJ, access should not be a problem. Cherokees are another story.

The adapter is sealed with o-rings, which have a habit of leaking with age.

After the Valve cover gasket, oil pan gasket and rear seal replacement I have oil dripping from that area. I guess the engine could have been replaced but I don't know I purchased it used.

Yes, if you have an adapter, it isn't factory in a TJ. Remove it and put the filter on the block. No clearance issues on a TJ.
