It is possible that this condition may be due to a parallax effect caused by the angle at which the timing marks are viewed. To ensure that any confusion is alleviated the correct way to view the the timing marks is from the left side of the engine looking beneath the power steering pump towards the torsional vibration damper (shown by the arrows in the illustration.)
