I am the author of the story and have been collecting and analyzing information on this issue for a few weeks. I specialize in stories involving technical service information and patents. It all came together earlier this week when I discovered the bore cooling patent and compared it to how the Mustang block is configured. I have done many similar stories in the past and have recently analyzed early build issue in a similar manner for the Civic Type R and the Alfa Romeo Giulia. You can usually catch my most recent patent discoveries on Tuesdays and Thursdays since that is when they are published to the USPTO website. In this case it worked out that the service information coincided with a patent and explained what might be happening. Thanks for reading and let me know if you have any questions.
