So if had alot of mixed answers to this question. So I need to get some actual answers I have a 2.0 duratec which is a 2010 it's at 126 thousand and some change. It was a fleet car from nicer which is a pretty good company around where I live my grandma worked for them and told me they have to take care of their cars. I'm not sure if the timing has actually ever been done one it. Iv been told since it's a timing chain that I dont actually really need to worry about it until its pass double what a belt needs and also been told different. Also if got this out of the blue lifter nise that occurred this morning, now my mechanic whom I trust more then I do myself told me that its bevuse it's getting colder outside and the oils thicker when it's cold. He said that since it goes away when the cars warm or with in a few minutes of running not to worry about it.
