This is what I read on the blue oval web site today.. 
I hope it's not true!
Sources at one of Ford's engine plants told BlueOvalNews that Ford Motor Company has instructed assembly plants to stop shipping certain 2005 model year vehicles because they can contain defective 4.6L or 5.4L engines. BlueOvalNews was first altered to the problem after we received a news tip at the end of August.
The products that can contain the defective engines include the 2005 Ford Mustang GT, 2005 F-Series, 2005 F-Series Super Duty, Ford Expedition and Lincoln Navigator. Ford has instructed the assembly plants to stop shipping vehicles until they are screened to see if they contain the defective engines. It is not known if any products were shipped to consumers before the problem was noticed.
The 2005 model year 4.6L and 5.4L engines in question were built with defective cylinder heads. According to sources, the defective cylinder heads will have an adverse effect on performance and will cause the engine to fail to meet Ford's specifications.
It's not immediately clear if Ford will replace the entire engine at the assembly plant or just replace the defective cylinder heads and approve the vehicle for shipment to customers.
