the duratec has a pair of chains...under the heads(?)...im a doof but i think i know that much...the rattle is a ford design flaw most of the older (95's) probably has done it at some point...my car has the rattle on start up but i haven't noticed it in awhile....there is not a recall but there is a technical service bulletin (tsb) from ford with a fix
if yours is getting worse better take it and get it checked...a couple cars recently suffered expensive problems
