Hi guys, cheers for your comments, it just felt like I was talkin' to myself (not that unusual some would say
). The Zetec, in all its various forms, is a cracking engine although the SE models that were built as a collaboration between Ford and Yamaha (I think) are a pig to do bottom end work on, apparently a special jig is required to locate the main bearing ladder frame accurately. Having said that I do find the lack of keys on timing pulleys to be a strange design "feature". Its certainly possible to pull the Zetec from a Focus and leave the box, driveshafts and subframe in place, don't know about Mundaneos though.
Good Zetec SE lumps are expensive though
