Abstract
An engine sump 4 has an oil suction passage 7 formed in its side wall to communicate with the sump well 6 at its lower end and to open upwards at its upper end to communicate with a passage in a crankcase 3. Preferably, the passage 7 opens into an upwardly opening gallery 13 in the top of the sump wall along part of its length. Two such oil suction pipes 7, 8 may be provided at opposite locations relative to a central point so that the sump 4 can be rotated 180 degrees about this point from one fitting position to another. A filter element 11 may be provided in the oil suction passage 7 and held therein by the crankcase 3.
