No. 1 oil nozzle sub-assemblies are provided on the cylinder block sub-assembly for cooling and lubricating the pistons.
These No. 1 oil nozzle sub-assemblies contain a check ball to prevent oil from being fed when the oil pressure is low. This prevents the overall oil pressure in the engine from dropping.
