easy fix, you have to pull oil filter housing off bock its one big nut behind filter, take filter off, take off nut and then wiggle off housing from block, replace o-ring and put backtogether, not real hard at all, we get them all the time in my shop, pretty common with 4 liter jeeps.My jeep is leaking oil just above the oil filter. 4.0lit not oil filter but were if gos into the block. how do
make sure its not the oil sending unit. That is right above the filter and when they get bumped they will crack and leak.
