I have been told that I need to have my timing chain replaed at 100,000 miles. I do not hear any rattle upon start up or while running. The maintenance guide does not indicate this as a item that has to be changed at any interval.

Has anyone had issues with yours, I have dad 2 ford dealers tell me they have not had any issues but the private mechanic said he has!

I want to drive to Texas In december of 2010 from Kansas but if it needs to be changed I will want this done before going.

Any advise?????????????
