- If key groove and timing mark are not aligned, rotate crankshaft clockwise one rotation and then counterclockwise one rotation. Verify key groove and timing mark are aligned.
- If key groove and timing mark are still not aligned, replace variable valve timing actuator. Refer to VARIABLE VALVE TIMING ACTUATOR under VARIABLE VALVE TIMING SYSTEM in REMOVAL, OVERHAUL & INSTALLATION article.
