07 f150 4.6 v8

Was told the spark plug came loose and blew my motor. Truck has 91000 miles on it. They are replacing the motor with a 2009 model 4.6 but should I worry about this happening again and it coming out of my pocket. Does anybody know if ford fixed the problem before 09.

First time I heard of spark plug coming loose and blowing an engine. I've fixed many spark plugs that have come loose and blown out of the cylinder but that can be repaired.

^ x2 Blowing the plug out of the cylinder shouldn't have killed the motor unless there were a ton of particles that happened to stay in the cylinder. If the new motor is a 2v 4.6, just torque the plugs to 28 ft/lbs and you won't have to worry about a blowout again.
