How far can we go on the original timing belt? The Mercury manual tells me to do everything under the sun at the apropriate intervals, but mentions nothing about a timing belt. However the Haynes Manual tells me to replace it at 60,000. My mystique is at 60,000 but the timing belt shows no signs of wear. How far have you all gone on your original belts? Can I damage anything if I just drive my mystique untill it breaks? confused
