Spark plug blow out. Yes it is available for inspection. Ongoing very common issues with triton engines blowing out spark plugs making a fire hazard because fuel vapor coming out of plug hole could be ignited by coil pack. All ford dealerships are very aware of this issue and have repaired many by rethreading and installing a helicoil thread repair kit at a very high price of 800 dollars and most repairs are temporary because the aluminum is weak and very thin at the spark plug hole. Ford is very aware of this ongoing issue and denies any liability experts don-€™t agree with fords arguments. No warning the plugs start to blow out at around 140000 miles well after the warranty. This problem started in the 90s all triton engines are affected. As in the photo the dealers attempt to repair was unsuccessful the spark plug is tightened to deep into the head and is broken off. They said at the end of the day I need a new head. 5000 dollars.
