The lubrication system features pressure regulated full flow filtration. The Balance Shaft Module (BSM) is mounted below the ladder frame and chain driven by the crankshaft. The BSM consists of a non-serviceable pump, oil pressure relief valve, and a non-serviceable balance assembly.

The lubrication system consists of the following components:

• Pressure relief valve in the BSM that controls system pressure
• Oil cooler mounted between the oil filter and the engine block
• Four piston oil cooler jets mounted to the engine block
• Filter screen for the Variable Valve Actuation Assembly (VVAA) mounted between the cylinder block and the cylinder head
• VVAA that uses pressurized engine oil to open the intake valves
