First thing I would do is unplug the vacuum pump by popping the headlight and starting the engine.
Many of these noises don't sound like typical chain noise to me. Chains sound more ... chain like.
Unplugging the pump or pulling its fuse and firing it up are quick and free way to eliminate that badboy from the diagnostics.
Just a thought, I have a fair amount of timing chain experience...

I have only herd one tiny peep from it since I changed the oil and filter myself. I use amsoil signature series and amsoil absolute filter. Maybe, if you don't tighten the filters enough the anti siphon valve does not work correctly.

For a 2014: AT4Z-6268-C for the chain, AT4Z-6K254-A for the tensioner arm and BA5Z-6L266-B for the tensioner it's self.
For my 2011: AT4Z-6268-A for the chain, AT4Z-6B274-A for the arm and BL3Z-6L266-A for the tensioner.
Notice the arm has a totally new part number. Others are just updates. I'm curious to know why the 14's get C and B versions of the parts, but they are not retrofitted to the older engines? These updates are just from the last 6 months or so. Last time I looked, there were no differences. There are additional updates to the other valve train components, but these are the three parts that I'm placing blame upon.

Thanks Brittany.
This is only the day after the first time I've heard the noise.
I tried catching it on video to help diagnosis, but cold this morning and twice more 5 hours apart "I could not replicate the problem" Lol.
I mentioned this to my service manager and shop foreman when I was there yesterday. Nothing was recorded as a complaint. I will monitor this noise closely and if I record more events I will book it in for service.
If you still feel I should send you my info in a PM to get this on record I will. I'm in BC Canada and I see you are Ford Service CA so I assume your the correct contact?

To answer your second question, I'm most certainly your best contact on the forum regarding any concerns you may have. If anything else comes up along the way, please don't hesitate to get in touch. You know where to find me now!

Then, send your information my way so I can assess the next steps. That diagnosis is important!
