Magnesium cylinder head covers provide trouble-free sealing, are lighter than aluminum and dampen valve noise. They are cast in two pieces to create internal ventilation passages with oil separators for crankcase vapor ventilation. This ventilation system virtually prevents the possibility of oil sludge formation due to the retention of water vapor in the engine.
