Abstract: An engine includes a filter housing with a base and a housing cover that contain a filter cartridge. The base defining a central recess, and having an annular sump extending downwardly from the central recess. An inwardly facing cylindrical sealing surface partially defining the annular sump, a drainage port defined in the cylindrical sealing surface and extending radially outward therefrom. The housing cover with a closed upper end and a downwardly extending annular wall sized to extend into the sump, the annular wall having a pair of seals that, when the housing cover is fully seated with the base provides a seal above the drainage port and a seal below the drainage port, the pair of seals precluding entry of oil into the drainage port when the housing cover is fully seated; whereby when the housing cover is raised upwardly, the lower seal is raised above the drainage port and oil in the filter housing drains out the drainage port.
