oil leak on 2002 Toyota Corolla

The oil leaks around the front cover where it meets the cylinder head and runs down from there.Only a few drops a day.Looking for any common problems so I know where the source might be.Too low for valve cover.Seems to be front engine at cylinder head gasket area.I believe its the gasket or front cover where the silicone is

Sounds like the timing chain cover is leaking. Not uncommon.
