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.

I was sitting at mc donalds getting food for my son, when a loud pop come from under my hood then my truck started to smell funny. Some cars were in front of me so they let me out. I pulled off to the side and called a few people that could tell me what was goin on. A man come and looked at it that worked on cars a crossed the street told me that it blowed a spark plug I never heard of anything like that. It had come completely out. There was oil on it. I had to have it redone so another spark plug could be put in there and now it has don it again. The same one number 2. Spark plug. This is crazy I don't have the money to keep fixin this truck over and over. I had to have it towed to my house when it blew the spark plug and I dono want to go though this again. Yall know that this is a default in theses vehicles but ur not doing anything about it. I have to use my truck to go to the doctors. And I can't go if it stays broke down. Yall need to take care of this problem ....
I have had 2 different spark plugs ejected from the engine on 2 separate occasions. The first time I took it in and had a heli coil installed. I have not repaired the second instance yet. There was a 2 year time span between the events. The first time it happened I was at low speed going through town. The second time I was on the freeway.
A spark plug blow out of the engine. I purchased a dorman kit to repair and replace the spark plug. I am concerned about driving the vehicle far from home for concern that another spark plug may blow out of the engine. Ford motor company should have made the issue with the engine cylinder heads not having thick enough material to hold spark plugs in the threads a recall.
The spark plug blew out of the head while I has just pulled out accelerating up a small incline. I was going through a major intersection with my son. There was a stutter, then knocking sound, less power, and strange odor.
#8 cylinder blew the spark plug out of the hole when the car was started
My expedition started acting like it was starving for fuel misfiring loss of power and there's a ticking sound coning from under the dash board the door lock unlock the lights flicker and horn beeps by its self I parked it and a couple days later it wouldnt it trying to crank but its sound I dont believe battery is dead if it was then lights wouldn't come on now and again also when I use my key ring lock to lock the door there's a clunk cluck sound I've spent a lot of money trying to find out what's wrong with lamont that's my expeditions name and nobody knows last repair shop had it 9 days total on the 7th day I called them they said they had no idea and on the 9th I went in and they said I needed a new motor costing 2600 and charging me 220 to tell me that. The shop before that cost me 350 saying the truck itself were the plugs go in was stripped and they needed a special tool. Any how I believe it would be a matter of time before the vehicle will catch on fire. The vehicle is very unpredictable and you dont know what it will do next it also dies while driving it ..
