The events leading up to the failure included startup of the vehicle and on the second occurrance merely driving the vehicle - a 2000 Ford Expedition eddie bauer 5.4 ltr Triton V8 with 90000 miles. The failure was of 2 separate spark plugs being blown from the cylinder head (both on the drivers side) a total of 3 times. The consequences was having the vehicle towed to a repair shop. The most recent repair was a recurrance of the same blown plug which happened in 2005. To correct the issues, the spark plugs were replaced and reinserted with repair kits to hopefully prevent future blowouts. Additional consequences are that I no longer trust Ford or my vehicles reliability. In researching this issue online, this is not a rare occurance and there have been vehicle fires where the spark plug has ruptured the fuel rail which sits directly above the spark plug holes. Consumeraffairs.com has this report: www.consumeraffairs.com/news04/2007/03/ford_spark_plug_fire.html. do we need to wait until some actually dies before action will be taken to have Ford do the right thing and repair this obvious defect?

Two weeks ago I replaced the spark plugs on my 2000 Ford Expedition and yesterday while driving to work I noticed a loud clanking noise. After investigating, I found that the #2 spark plug had been blown from the cylinder head. The Expedition has 10300 miles on it and has been very reliable.

The vehicle was running rough, and the service engine light appeared. Took vehicle to the dealer, and they said manifold was cracked.
