... and two engines.

Apparently the #8 piston was installed with a sledgehammer, which dented the top of the piston, shattered the lands, and broke the compression and oil rings in about a dozen places. That big missing chunk of piston land was gone for quite a while, hence the carbon buildup in there.
As bad as it looks, the car actually ran pretty well except for a little vibration at idle and a check engine light.
Ford completely stood by their product and put a new 2013 service replacement engine in the car. Grapevine Ford did a great job and I am happy as a pig in shit to have it back!
Thank GOD I never modified the car. The first questions from everyone at Ford were "Do you have an intake" and "Have you done a tune". Not that it would have automatically voided the warrantly, but it probably wouldn't have been painless either. As it worked out, it went right through the process and I got the new '13 coated pistons.
