What Ford motor blows out spark plugs?

Ford Motor Spark Plug Blowouts
Ford motors, particularly the 4.6, 5.4, and 6.8 modular engines, are known to experience spark plug blowouts. This issue is common in various Ford vehicles, including F150 pick-up trucks, Mustangs, Crown Victorias, Vans, Expeditions, and motor homes. The blowouts are attributed to the failure of aluminum threads, leading to the spark plugs being blown out of the cylinders.
The problem seems to occur most often on 5.4L Triton engines, but may also occur on other V6, V8, and V10 engines in these vehicles. The #2, #3, and/or #4 spark plugs tend to work loose and blow out when the engine has 60,000 to 100,000 miles on it. When the plug blows out of the cylinder head, it usually damages the threads in the spark plug hole and also breaks the coil that sits.
Ford 4.6, 5.4, and 6.8 liter engines are prone to spark plugs being blown out of the cylinders due to the aluminum threads failing. There are many different brand spark plug thread repair kits available for the common Ford spark plug blowout problem, however, they are not all as effective and long-lasting as the recommended solutions.
As a result of this issue, Ford dealerships routinely insist to consumers complaining about a spit spark plug that they have never heard of such a thing happening. The repair work for this problem is expensive, with Ford not authorizing any type of thread repair to correct this concern.
To prevent this issue, it’s recommended to check the spark plugs on these engines every 20,000 to 30,000 miles to make sure they are not coming loose. If a plug feels loose, it should be tightened to the recommended torque. If an engine blows a plug, the fix can be expensive, as Ford insists their dealers replace the entire cylinder head, which can cost up to $3,000 for parts and labor.
In summary, the Ford 4.6, 5.4, and 6.8 modular engines are prone to spark plug blowouts due to the failure of aluminum threads, and the repair work for this problem can be expensive.
