NOTE:

Use a ratchet with a 24 mm socket to rotate the vibration damper. Always rotate the vibration damper in engine rotation direction to TDC. Do NOT rotate the vibration damper backward to get to TDC!

The notch on the vibration damper must line up with the arrow mark on the lower timing chain lower cover (use a mirror to see, if necessary).
The marks -1- on the camshafts must point upward.

-- Measure the distance from the timing chain guide rail inner edge -A- to the mark -B- on the intake camshaft.
