" My mercruiser 120 has a little water in the oil. When I run it the oil level doesn't seem to rise. Is it normal to have a little water in the oil? The oil on top of the lifters is milky brown and it has that white build up on the fill cap and in the pvc tube. Also, when running at high rpm some steam or smoke appears to be coming from the carb air cleaner. "
