I have noticed the same ticking. Took it in to dealer last week and was told that tech confirmed the noise. Then ... was told that Ford is aware of issue and has instructed dealers not to try and fix until they research and develop a solution. They "think" the issue is not causing harm and would let me know when a TSB is issued by Ford.
When I asked how long I should wait to hear - I was told not to worry, they would be in touch.
I am 2K away from first oil change and plan to follow up then. Will report back when I know more.
