OUTLINE
The lubrication circuit is fully pressurized and all oil passes through an oil filter.
A trochoid gear type oil pump is used.
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.
This engine uses a Variable Valve Timing-intelligent Wide (VVT-iW) and Variable Valve Timing-intelligent (VVT-i) systems. These systems are operated by the engine oil.
An oil filter with a replaceable element is used.
