Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Our 1998 Ford Expedition with the 5.4 V8 Triton engine had another spark plug blow out of the cylinder head. The last time this happened was about 3 years ago, it was the #3 cylinder plug then and last week it was the #6 cylinder plug, I searched the internet concerning this problem and found hundreds if not more of the same issues, and no one is making Ford do anything about this, just thought my voice in this matter might help. Please if there was ever an instance of a recall this is surely one. This is getting very expensive for the auto owner, the first time we had it fixed by Ford and it was $250 and this time it was over $1,000. Thank you for addressing this issue.

A spark plug was ejected from the cylinder head. Interior of the SUV filled with gas fumes. There was nothing noticeable prior to this occurring. This is the first time this occurred. The mechanic obtained the repair kit to rethread the cylinder head at a cost of $360. The work is not guaranteed...if it happens again, the head will need to be replaced at a cost of thousands of dollars.

Plug blew out of head. Had someone look at the truck and they said that it's common for that truck to do that so I checked with another garage to see what they had to say and they told me the same thing.so why is there not a recall on this?

My 1998 Ford Expedition blew out a spark plug on the highway while I had my baby daughter in the truck. I lost power and had to swerve into the slow lane almost causing multiple accidents. This is the 2nd time this has happened and still no recall.

As I was driving I heard a loud clattering noise. In a few seconds it became louder. I shut the engine off. My husband came and drove the Expedition approx 1/4 mile home. The # 4 spark plug blew out of the head. It slammed the coil pack into the fuel rail and cut the fuel line. As of this time, we have not repaired the vehicle yet.

Under normal driving condition spark plug blew out @ 1250000. Previously a different spark plug had blown out @ 40000 and was repaired with a helicoil. Repairs were underway. This appeared to be a very common problem with these 5.4L engines!

1998 Ford Expedition, Triton engine, forcible ejection of spark plug. Threading stripped from cylinder head will not allow reinsertion of spark plug. Cost to repair per Ford service $4000. Ford refuses to acknowledge this as a manufacturing defect and issue recall. No guarantee if repaired that same failure will not occur again. Probable cause: Poorly designed aluminum cylinder heads with insufficient threading to retain spark plugs.

A spark blew out the engine leading to major engine damage. To further hurt the Ford reputation they said it would cost my life savings to repair it when I had it towed to a reputable mechanic my findings is that it would only cost half of my life savings not only was I told this but then I find evidence that there is a huge cover up.please lord don't let my government be caught up in this mess this corporation has a lot of influence but the american people have a right to live in a just society we the people are what this nation is made from and corporations come and go.

: the contact stated while driving 35 mph a spark plug blew out of the cylinder head due to the thread holding the spark plug into place and the engine stalled. The vehicle was taken to the dealership for inspection. Upon inspection, the dealership put a heli coil in the cylinder head and replaced the spark plug, which remedied the problem. Updated 3/9/2006 - the first failure occurred at 48000 miles on the #2 cylinder. The plug was blown out of the cylinder head. The latest failure was on the #7 plug.
