Report: A Spark Plug Could Blow Out of Cylinder Head
Ford Excursion Problem
Engines Affected: 5.4L V8, 6.8L V10
Average Mileage: 169,125 mi (134,000 mi - 215,000 mi)
There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

2 seperate occurrances of a single spark plug being ejected, starting around A-75,000 miles and a different plug, B-125,000 miles. This Excursion is not used for towing; It has a normal (easy?) duty cycle.
After second ejection, all on the drivers side, all unaffected spark plugs holes were repaired anticapating additional, new failures. No apparant failures on the passenger side of V10. One blowout, A-75,000 miles, that was repaired, cylinder #9, appears to be failing again, possibly because the new spark plug was cross-threaded into the repaired cylinder head.
