You would need to Clean & have a good look to be sure it is not coming from the Rear Main Seal
The Oil Filter Plate is also a know issue.......
IF you replace the Oil Filter Plate Gasket, I would use RTV Form A Gasket, but you have to be sure the Block & Plate are very clean & let it dry for at least 24 hours in a 60 degree or above climate
Since the Plate is likely the Aluminum one, be sure the Mounting Surface is not pitted or cracked
IF it is, replace the Plate

let me know if you need further
