Timing Component Alignment Marks








NOTE: BMW does not rely on timing marks for precise engine timing. Correct basic engine timing is achieved when the camshafts and crankshaft have been locked into exact alignment with special tools prior to timing chain installation. Refer to Timing Chain : Service and Repair : Line Up the Crankshaft & Camshaft

CAUTION!: Incorrect setting/installation without the use of special tools could damage or break the camshafts. Valves could also be bent through contact with the piston crowns. Always note installation instructions and use specified special tools, procedures, and sequences.
