DI Diesel Engines M57/M67 - Common Rail Sec. 2 P.20
Course contents/Background material
Oil pan
The oil pan represents the bottom end of the engine and serves as
an oil collection reservoir. The position of the oil pan (sump)
depends on the design of the front axle.
M57-specific features
• Aluminium die cast with integrated thermal oil level sensor
• Oil pan gasket designed as metal-backed gasket (same as on
M47, common part E38 and E39)
• Return flow pipe (E38) so that oil from the oil separator can
return to the oil sump below the oil level (blow-by gases)
