First the Gasket is Fel-Pro 72423

1. Drain oil.
2. Remove oil filter.
3. Remove the three fasteners retaining the oil filter adapter. One stud. One bolt and, one nut. Remove Adapter and Clean area.
4. Replacement is the reverse of removal.

Here are some diagrams (below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
