• 1 - Right cylinder head cover.
• 2 - Left cylinder head cover.

The cylinder head covers can be distinguished from each other by the shape of the interior engine oil channels. Both cylinder head covers are in aluminum. Along the lower surface of the cylinder head interface, there is a rubber gasket (sitting on the cylinder heads).

• 2 - Hydraulic tappet deactivation solenoid valve housing.
• 3 - Exhaust side phase sensor housing.
• 4 - Exhaust side solenoid valve transformer.
• 5 - Intake side solenoid valve transformer.
• 6 - Ignition coil housings.
• 7 - Intake side phase sensor housing.
• 8 - Housing for oil pressure sensor of the hydraulic circuit to deactivate tappets.

• 1 - Additional oil pump.
• 2 - Solenoid valve to lubricate right turbocharger.

The left side cylinder head cover has the oil channels inside needed to lubricate the housing where the high pressure plunger runs, the oil channels that supply the solenoid valve phase transformer; the exit opening for turbocharger lubrication and the oil channels (in blue) of the hydraulic tappet deactivation circuit.

The additional oil pump for the cylinder deactivation circuit is fastened in part to the cylinder head cover (the other fasteners are on the head) while the right turbocharger lubrication solenoid valve is seated in a housing obtained entirely in the cylinder head cover.
