Did they determine then that it was an issue with the timing chain?

No they replaced everything from the water pump to changing everything under the timing cover and it still did it. Then the day ford was going to send in an FSE. Ford called and says we have just released a tsb for adding a new timing cover with provisions for adding a tensioner and pulley for the ac belt to eliminate the stretchy belt. Once they did that. Problem gone.
Picked car back up today. Tick seems to be gone. Pretty stoked. They did do a TSB but wouldnt say which because it wasnt a TSB that covers the 2013 cars but the ford hotline told them to do it and it apparantley worked. It included as stated as another above: belt, timing cover, and crankshaft seal. Knock on wood the car drives/sounds great and the exh baffles are finally removed as a celebration haha. Just in time for a couple car shows this weekend (weather permitting).
Can you post part numbers from the repair order?
Wow! Nice! I have a faint tick as well, but I'm hesitant to have them tear the front of the motor apart for a new timing cover if there is no concern of damage and it's just a new tensioner on the timing chain....
That's the numbers from the tab referenced earlier, belt, timing cover and crank seal. Interesting because that tsb is for 2012 models, wonder if they will update it to include 13s. Nice to see they didn't use the xl 17 additive that has been discussed on other boards. It's interesting that a belt issue makes a sound which almost sounds like an internal engine noise
That's my post on the other thread. Ford Customer Care said it is most likely the tensioner TSB. I spoke to another guy on the forum and he has a 2013 with the same noise. The dealership performed the TSB, no more noise for him. Mine gets fixed on Tuesday.
I was half tempted to put in the XL17 but didn't.
Do you know the TSB number on that? I may run it by my dealer and see what they think...thanks!
