OUTLINE
The lubrication circuit is fully pressurized and all oil passes through an oil filter.
This engine has an oil return system in which the oil is force-fed to the upper cylinder head sub-assembly and returns to the oil pan sub-assembly through the oil return holes in the cylinder head sub-assembly.
A cycloid rotor type oil pump is used.
