• Support spar concept as on the M47 (i.e. interconnected horizontal and vertical box profiles)
• Cast flange for mounting common rail high pressure pump
• Reinforcement shell with integrated oil deflector function, split design in area of cylinder 1 to 2 (oil pump)
• Oil spray nozzles (common part M47)
M67-specific features
• Cast starter flange on both sides, cast timing case
• Integrated water flow control to water pump
• Oil supply gallery for oil spray nozzles with central pressure control valve
