M57/M67 – Valve timing M57

Setting ignition TDC at cylinder No. 1

We recommend the following procedure in order to check the valve timing in assembled status, i.e. with the cylinder head mounted in position:
• Remove camshaft sensor
• Turn camshaft until sensor cam approximately faces upward
• The crankshaft is now located just before the blocking position
• Continue to crank engine in direction of rotation until blocking pin locks into flywheel
• Sensor cam on camshaft has drifted out of the centre position in the direction of the high pressure pump
