ABSTRACT:
A magneto casing for an engine connected to an engine crankcase in liquidtight sealing relationship by means of an oil seal which permits small amounts of air to pass therethrough is formed therein with an air passage having mounted therein a filter which is repellent to water but permeable to air. When the internal pressure of the magneto casing undergoes changes due to variations in the pressure within the crankcase which occurs when the engine operates, only air is allowed to flow into and out of the magneto casing through the filter in the air passage and water is prevented from entering the magneto casing.
