A coolant filler neck assembly for a pressurized cooling system. The coolant filler neck includes a cylinder housing defining a non-pressurized coolant overflow reservoir; an upper cap member attached to an upper region of the cylinder housing, the upper cap member including an overflow inlet port member arranged internally in the coolant overflow reservoir and a filler pipe member in fluidic communication with the overflow inlet port member and the pressurized cooling system; a first fluid overflow tube member arranged internally in the coolant overflow reservoir to extend in a longitudinal direction though a first region of the non-pressurized coolant overflow reservoir to direct overflow liquid coolant to the non-pressurized coolant overflow reservoir; and a second fluid overflow tube member arranged internally in the coolant overflow reservoir to extend in a longitudinal direction though a second region of the non-pressurized coolant overflow reservoir to direct the overflow liquid coolant from the non-pressurized coolant overflow reservoir to the ambient environment.

An internal combustion engine assembly includes a crankcase and a cam housing. The crankcase includes a crankcase cavity configured to receive a counterweight. The cam housing includes a cam housing cavity configured to receive a camshaft. A pump is positioned within the cam housing. The pump is configured to draw oil from an oil reservoir defined by the cam housing cavity. A crankshaft supports the counterweight for rotation therewith. The crankshaft is rotatably supported within the cam housing and is coupled to drive the pump. A bearing supports the crankshaft between the crankcase cavity and the cam housing cavity. The bearing includes an outer race. A seal is positioned between the pump and the bearing. The seal is positioned against the outer race to block the transmission of pressure fluctuations between the crankcase cavity and the oil reservoir.
