About a year ago the cylinder head gasket on our 1999 Ford Expedition was replaced due to leaking oil, by the dealership. The mileage was 35,000. Now a year later, while traveling at 70 mph. On the freeway, a spark plug blew out of the same right cylinder. The loud noise and clatter caused a knee jerk response,almost causing an accident. The vehicle's mileage is now only 46,000. We feel that Ford should do the responsible thing and recall these 5. 4 l engines with the aluminum cylinder heads and and replace them with a better design with safety in mind. If you check other consumer compaints, you will see that this is not an isoleted incident.
