Remove the old filter. Replace it with a new filter. Before installing the new filter wipe the mounting surface clean and apply a coat of oil to the new oil filter's gasket. Spin on the filter and tighten it 3/4 turn after it makes contact with the mounting surface. No, more and no less. If you still see oil leaking from the filter then look above the filter for the leak. Possibly valve cover is leaking.
The oil filter may be lose.
