The oil filter adapter bolts to the block and carries full oil pressure, so the seals at that joint are not optional. This is the small inboard seal in that set. A weeping adapter seal looks like a leaking filter or a bad oil cooler, and it is worth replacing both seals whenever the adapter comes off rather than chasing the leak twice.
