The crankcase is integrally provided at the bottom, and the cylinder head is fastened to the top with multiple mounting bolts located between each cylinder bore on both the left and right sides of the crankshaft, while an oil droplet extending upward from the crankcase is provided on the side. A passage or a blow-by gas passage is formed, and an upper end opening of the oil drop passage or blow-by gas passage is communicated with an oil drop hole or a blow-by gas relief hole bored at a position outside the mounting bolt in the cylinder head. In a cast cylinder block, the oil drop hole or blow-by gas passage in the cylinder block is connected to the crankshaft from a position directly below the oil drop hole or blow-by gas relief hole in the cylinder head with an opening to the crankcase at the lower end thereof. A cast cylinder block for an internal combustion engine, characterized in that it is bent so as to communicate with a crankcase at a position displaced by an appropriate distance in a direction parallel to the cylinder block.
