Water in the Crankcase.
A number of the troubles encoun tered in winter operation are caused by water in the crankcage. Just how this water gains entrance, how an excessive amount can be avoided, and also low some of the attendent trouble can be avoided can best be explained in the following manner:

This may result in burned out bearings or scored cylinder walls. or a slush and the ice crystals will The water may freeze in the form clog the oil screen preventing oil- circulation. The slush will stick to the side of the crankcase and may not run out when the crankcase is drained. If this water is not re- moved when the crankcase is drain- ed trouble may be experienced after fresh pil is added, owing to the
