Here's a DIY on replacing the oil filter housing gasket.

If that is the problem I would recommend using a gasket made from Viton. It cost more than the stock gasket but will last much longer. You can get it here: https://www.bavauto.com/11-42-1-719855v |
If the oil is on the driver side of the engine and not on the passenger side of the engine you should inspect the OFHG.
