Spark plug ejection from cylinder head
On september 6, 2005, odi received a petition requesting that the agency investigate allegations of engine spark plug ejection in certain model year 1997 through 2004 ford vehicles with triton v-8 and v-10 engines.odi received a total of 474 non-duplicative complaints on the subject vehicles where the complainant, or the dealer repairing the vehicle, reported that a spark plug detached from the cylinder and/or ejected from the engine.as of december 8, 2005, odi is not aware of any allegations where the alleged defect resulted in a loss of vehicle control, a crash, an injury, or a fatality in any of the 10,319,810 subject vehicles.in addition, odi is aware of only two incidents where the vehicle stalled without restart.information contained in the odi consumer complaints and obtained from 72 telephone interviews with complainants showed the following:(1) 99% of the complaints were on my 1997 to 2002 subject vehicles.(2) most the complainants reported hearing a loud pop while driving or upon starting up the vehicle followed by a loud, repetitive clicking or popping sound.(3) many of the complainants reported that the popping sound was accompanied by some loss of vehicle power; however, in 99% of the incidents reported, the vehicle did not stall.in the very few incidents where the vehicle did stall, most vehicles could be restarted.(4) only a small percentage of the complainants cited that they smelled gas or a slight burning smell when the incident occurred.(5) in all but a very few incidents, vehicle damage was limited to the engine.in one incident, the complaint reported that the fuel rail was damaged and replaced after one of the spark plugs ejected from the engine; however, the complainant reported that the damage did not result in any type of fuel leak or fire.in another incident, the only incident where a fire was alleged, the complainant reported that no fluid leak was observed, but that a fire resulted after the spark plug had ejected from the engine and he had restarted the vehicle and driven to another location.none of the complainants reported any damage to the vehicle hood.(6) only two complainants reported that they observed what appeared to be some drops of fuel coming from the cylinder where the spark plug had failed or on the spark plug itself; however, each of these complainants reported that there was no smoke or flames as a result of his incident.as the petitioner noted, and odi?s analysis showed, it is possible for a spark plug to detach from the engine cylinder threads in the subject vehicles.however, odi?s analysis of 474 complaints describing such incidents found only a very few alleged any safety-related consequences.none of these showed any evidence of a serious safety consequence.given the large population and relatively long exposure time of the subject vehicles, the complaint analysis indicates that the risk to motor vehicle safety from the alleged defect is very low.in view of the foregoing, it is unlikely that the federal safety agency would issue an order for the notification and remedy of the alleged defect at the conclusion of the investigation requested in the petition.therefore, in view of the need to allocate and prioritize the federal safety agency?s limited resources to best accomplish the agency?s safety mission, the petition is denied.

What 1999 Ford F Series owners say
Most recent owner complaints, unedited.
While driving, there was a loud explosion, then engine was running rough and loud. Mechanic stated that due to a faulty design, the #7 spark plug had been shot from the engine, damagine the ignition coil and allowing fuel to spray from the injectors onto the now loose spark plug. Mechanic stated I was lucky this did not result in an engine fire. Engine is ford 5.4l v8. Mechanic explained that the design of the engine means that the aluminum heads have approx. Half as many threads as a normal spark plug, meaning that this is a frequent occurrence and ford is aware of the fire risk but has chosen not to address.
I've had two plugs blow out on my 99 f150. It has less than 100,000 on it. If they know its a defect why not step up and fix the problem? It cost $300 a plug!!!! Left me stranded at night with my family along the road!! Makes me wonder if I want to stay with ford or go elsewhere.
I had just got off work and was leaving the parking area and blew out the number 4 sparkplug on the right side head. I shut off the my truck and parked it. I called a friend that lives close for a ride home. The next morning I drove back to the plant and took my truck to the local ford dealership. They said that I should replace the head or install a helicoil and also replace the spark plug and coil pack. So I had them install the helicoil and replace the damaged parts. Less then a month later I was driving to work on the I 90 and I blow out the number 5 cylinder spark plug and this time it took out the plastic shield and ripped the spark plug and the coil pack off he truck. I have not done any thing but contact ford motor company about this at this time. There suggestion was to replace the heads my self at a cost of 6,000 dollars.
I was driving my 1999 ford f150 4x4 with 5.4l engine home from work and stopped at traffic light. The light turned green and I proceeded to go and then "pow" the truck began to make a loud "popping" noise and lost all engine power. I was in the middle of the intersection and somehow managed to keep it running long enough to get through the intersection and on a side road. I hesitated to open the hood because of the strong gasoline smell but it wasn't on fire "yet" so I opened it and found one of my ignition coils (coil packs) loose on top of the intake manifold. Upon further inspection I realized the spark plug had blown out of the aluminum cylinder head. I was able to catch a ride to the auto parts store with coil and plug in hand. The salesman at the store immediately knew what had happened and even knew the engine was a 5.4l before being told. He said that if I was lucky I would probably just have to install a helicoil or threaded insert in it. The other option was to replace the cylinder head. I purchased new coil and plug then drove back to my truck. I tried to clean the threads with a spark plug thread chaser but there were no threads left to clean. I searched the web and found numerous complaints of the same issue. Some people said they had multiple spark plugs blow out or "spit out" on the same vehicle. Why doesn't ford have a recall on this? The gasoline smell was due to the fuel injector still spraying while the plug was blown out of the head. What if it had caught on fire? I haven't repaired it yet but will try the "repair kit" that was handed to me when I bought the coil and plug. I think ford should recall all the 5.4l engines that have this problem and install the helicoil or insert to prevent a customer breakdown or a potential vehicle fire.
Blew out sparkplugs and broke bracket on the side of coil packs. Don't like paying $85 a pop for ford's poor design. Plus the healy coils or maybe that's the motive. This happened three different times.
My family and I were 25 miles from home in our 1999 ford f-250 when a spark plug blew out of the head. I had the truck towed to the ford dealership and was told that even though the truck had less than 75,000 miles. I had to pay for the repair. This repair cost us over $3,000.
1999 ford expedition first blew out a spark plug in 2003 due to too few threads in cylinder head. Mechanic was able to repair for around $500. The problem occurred again on another spark plug in 2004 which destroyed the whole engine. I contacted ford and was told they could do nothing about it. The refurbished jasper engine ended up being around $5400. The old engine was turned in to avoid a core charge. I have all of the paperwork from the mechanic stating the problem.
I blew a plug on my ford f150. Engine has had proper maintenance. It has about 80,000 miles on it. 5.4 v8 year is 1999. Called ford and they will no acknowledge a problem and will do nothing to reimburse any of the repair costs. I think it is a faulty head on the triton engines.
