Interesting , I have a Zetec too. Seems to be controversy on weather it is an "interference" or "free wheeling" engine. both my local Ford dealer servcie man and gates.com say it's a free wheeling engine. So if your timing belt does goit won't damage the valves. I bought one with 96K on it with the original timing belt. I replaced the belt but the old one looked near perfect after 96K miles!? Ford does not list a belt change in the maint. schedule. they say "good for the life of the car".
