Last post for this past owner. Timing chain never made a sound or ran rough till on the way to last mechanic for quote on changing out chain.  Started running rough when dropped it off. Shop hooked up to their computer, now showed P0016 & P0018 codes. Diagnosed with timing chain stretched & jumped teeth. Recommend replacing engine. Best I found was used engine & install, $5,500.00. Had to borrow against Home Equity to write check to bank to get the title.  Sold beautiful 2012 Lincoln MKS for $3,000.00.
Most Unfortunate.
Good luck all you with the Ford 3.5 ecoboost engine.  After lots of research, way too many of these engines having this same problem. Ford service told me Ford knows it has a problem, fixed it for the 2017 model.

Sorry to hear.  A timing/water pump job is about 2000$ or less at an independent.  A new engine was not needed.  What did you buy as replacement?
2007 Ford Edge SEL, Powerstop F/R Brake Kit, TXT LED 6000K Lo & Hi Beams, W16W LED Reverse Bulbs, 3BSpec 2.5w Map Lights, 5W Cree rear dome lights, 5W Cree cargo light, DTBL LED Taillights

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

I think it's because there was evidence the timing chain skipped teeth they are recommending new engine
