Driving home from doctor visit, heard a loud pop, and lost power, very loud engine noise as if I had no exhaust. Mechanic looked at it apparently the engine blew out a spark plug making it necessary to replace the cylinder head since it stepped the treads. And also broke the coil. Am on disability and fixed income, the repair cost is so high I have to wait and be without a car. Do not know what to do. The mechanic told me it is a common problem with this vehicle and ford. And I researched the web and found out that many others experienced the same thing. Furthermore when going to ford for repair, they say that the new head is a improved version. So if it is an "improved" version that mean that they know that there is a problem with the product to begin with. Ford should replace the faulty heads at no cost to vehicle owner.

I own a 1999 ford expedition and my family has experienced (3) blown spark plugs! The triton engines ford makes have aluminum heads and spark plugs are blowing out. On may 6, 2008 was my first experience (cost $273.03) replaced helie coil. July 18th 2nd blowout with 3 young children late at night. Police officer has had 2 blown spark plugs on his ford! (cost $1,502.02) had to remove head. #3 blowout last night pulling into my driveway with family on board. I will not take this vehicle anywhere again as these explosions can cause a car fire and I will not risk that or being stranded in remote camping area. I have wrote a letter to ford board of directors- called ford directly and at this time there is "no customer satisfaction programs" according to "amy" my case girl. Google "ford triton engine blown spark plugs" and you will see the many consumers frustrated and experiencing this. If my car catches fire and my family is injured or killed I will hold you and ford personally liable as this is my written notification of this defect. There needs to be a recall and it needs to happen now!
97 to 99 5.4 fords like to blow plugs out of the cast aluminum cylinder heads. They doubled the threads in 2000. It occurred to my 99 expedition,out of warranty don't expectancy help from ford maybe your dealer. My expedition was 4 years old,at the time. Best advice buy gm forget about ford unless you own a tow truck.
My wife was driving to colorado springs on hwy 24. She pulled away from a stoplight when she heard a loud slapping noise. She was able to get to the side of the road safely, despite heavy traffic. We had the ford expedition towed to the dealer we bought it from. They have called me to tell me the number 7 spark plug blew out of he block ruining the threads that hold it, in addition the coil pack was ruined. I have a warranty on this vehicle (it was bought used), the service manager is telling me they will not cover this under the warranty because it is a "maintenance issue". I informed him that I will not pay for this repair and he said he would call ford to see what they are doing, lol. If my wife had been traveling at hwy speeds she could have crashed and the possibility of a fire was real because of the fact fuel was coming out of the spark plug hole and the coil pack was still firing. Something must be done.
Two weeks prior to this failure, there was a distinct ticking noise that changed with RPM. Sounded like a collapsed lifter. While returning home on memorial day 2008, experienced a loud popping noise, followed by continued whoosing noise and poor engine performance. After inspecting engine, noticed #7 spark plug had come out and broken the coil-on-plug coil unit. Failure occurred 2 blocks from my home, so I limped it home. Have not had it repaired yet.
Attn: I apologize first submission was incorrect phone number: this contains proper contact phone number 1999 ford expedition #3 spark plug blowout.
1999 ford expedition #3 spark plug blowout.
I was getting a loud noise from the passenger side when I would accelerate. I took it to the shop and found that all of the nuts and studs holding the exhaust manifold to the engine had rusted away. The tech said it is a common problem he finds with fords. I also talked with a guy and he had the same year truck and had the same problem. I have a friend who is also a auto mechanic and he sees it often as well.
Ford expedition - spark plug was ejected from cylinder.
Tl*the contact owns a 1999 ford expedition. The failure occurred in october 2007 and the again on march 21, 2008. The spark plug came out of the engine while driving 25 MPH. He found the spark plug sitting on top of the engine. The service engine soon light was not illuminated until the following day after the failure occurred. The mechanic stated that your number three spark plug blew out the engine block. He also stated that if he were driving faster than 25 MPH the spark plug would have gone through the hood and then the windshield. The manufacturer stated that the failure was not covered by the warranty and they are unable to assist him with the repair. The estimated cost to repair the vehicle was $3,000 to $7,000. The contact also filed a complaint with the consumer protection agency and was not given a case number to reference. The vehicle was serviced on a regular basis. There are invoices available to show each time the vehicle was serviced and diagnosed. The failure mileage was 11622 and the current mileage was 13000.
Spark plug # 3 blew out of 4.6 triton ford engine in our 1999 expedition. Looking at internet data this seems to be a very common theme with the triton engines. Cost us over $1,000 to fix.
On my 1999 ford expedition I noticed the smell of hot oil. When I would stop and park the vehicle the smell became stronger and smoke would come up around the hood of the vehicle. I also noticed some oil drops on the ground. Upon taking the vehicle to the local ford dealer I was informed the the head gasket was leaking oil on the rear of the right head. Cost to repair was $1,295.04. I then found on the internet that this was a know problem and was widespread. Apparently there was a manufacturing defect in the head which would cause an oil leak in the right rear or left front of the head. Again this was a know problem by ford but no recall has been issued and if your vehicle was not under warranty the owner had to absorb the repair cost. To me this was a safety issue and should have been addressed by ford. The oil was leaking onto the exhaust pipe and could have caused a fire.
The #3 spark plug blew completely out of my 1999 ford expedition, ford refuses to repair it saying that it must have been the result of some sort of abuse of the vehicle. After seeing thousands of these type of complaints from this particular engine class, it is reasonable to conclude that this is a serious design flaw, if the fuel rail had been compromised, the end result certainly would have resulted in a fire. I think that you should require ford to either repair the affected defective engines, or compensate the owners for their repairs...
Tl*the contact owns a 1999 ford expedition. While driving 65 MPH, the contact heard a loud popping sound under the hood. The vehicle decelerated to 0 and would not accelerate. The vehicle was towed to a dealer. The dealer stated that the spark plug popped out and stripped the engine head. One of the engine heads has to be replaced. The current and failure mileages were 70,306. Updated 02/15/08.
1999 ford expedition 5.4 motor blew spark plug on passenger side-rear plug.
I own a 1999 ford expedition. Yesterday, my fiance and kids were on their way to school when the engine failed. Upon inspection, we found that the engine had ejected the #3 spark plug on the passenger side. This caused the coil pack to "shatter" as well as the plug cable attached to it. I've done extensive searching on the subject, and there have been incidents reported of fires caused by these plug ejections. Also, hundreds of consumers have been stuck with repair costs of several thousand dollars. This is a common problem and should be addressed as a recall. Lives are at risk.
1999 ford expedition 5.4l while driving heard loud noise from engine compartment. Pulled over and lifted hood seen that number 3 coil was moved and sparkplug ws attached. Plug had been blown out of sparkplug hole and stripped the threads out as it came out. Gas was being blown out of plug hole and the sparkplug was sitting right next to the gas coming outmaking a possible fire hazard. Have to have cylinder head replaced to fix stripped threads.
Started my vehicle and heard a loud noise followed by a steady popping noise. I opened the hood and found the rear spark plug on the passenger side had been blown out of the engine. I have since read hundreds of other complaints of this occurring, some causing fires.
Tl*the contact owns a 1999 ford expedition. In 2005, while driving 55 MPH, the contact heard a popping sound and stopped the vehicle. He noticed that the spark plug had come through the engine. A month later, the failure recurred. The purchase and incident dates were unknown. The current mileage is 130,000 and failure mileage was 90,000.
Dear sirs, I own a 1999 ford expedition, the engine seemed to be have operated fine until the # 3 spark plug blew completely out of the cylinder head. If the plug and the destroyed coil would have ruptured the fuel rail the vehicle would have gone up in flames. I hope that something can be done on the part of ford to repair this unbelievingly, amazing , and very common safety problem ford was brushing under the rug. The vehicle was past the waranty period so that won't be of any help, but this problem was incredibly dangerous
Spark plug ejected, very inconvenient, vehicle is not drivable can not afford to repair need the car for work.
Tl*the contact owns a 1999 ford expedition. The contact stated that he heard a loud popping sound when the vehicle was started. The vehicle was towed to the dealer who stated that there is a defect with the cylinder head, which caused the spark plug to disengage. The current and failure mileages were 86,800.
Tl*- the contact owns a 1999 ford expedition. He was having problems with the aluminum head spark plugs, the number 3 & 4 cylinder failed, and the mechanic told him it was a design flaw. The failure was caused by not having enough thread in the aluminum spark plug head. He needed a new engine or a head job. It will cost him over $3000. He stated that there was a service bulletin for this problem. The current and failure mileage were both 110,000.
5.4 triton engine spark plug blown at 77,000 miles on my 1999 ford expedition.
Under normal usage at @ 135,000 miles oil began to leak from the rear of the head gasket on the passenger side of the engine. There are at least five tsb's in effect for this problem. No repair has been made account prohibitive cost. Truck being driven. Adding 1 quart of oil about every 2 weeks.
Head gasket failure. Right hand, rear side of the engine. I can smell strong burning oil when engine is running and after shut-off. Oil saturated starter.
I was driving on a busy road with my three children during rush hour. I heard a loud pop followed by the what sounded like machine gun fire. I immediately pulled over to the side of the road and shut down the vehicle. I was fearful of the safety of my children and had them leave the car. I then had the vehicle towed. A ford repairman looked at the car and stated that the #3 passenger side spark plug blew out. He stated that this a known problem and ford refuses to acknowledge the issue. He said that they see many of these each week and that it is usually the #3 spark plug on the passenger side. He stated that it would be $2500-$5000 to repair the vehicle. We were told by another ford dealer that he could fix it for $300-$500. We had the vehicle towed there and despite informing him which spark plug it was, upon inspecting the vehicle he claimed it would be difficult to repair and increased the repair price to $2100. When we objected he offered to purchase the vehicle for $200-$300. We feel as if the ford dealers are using this issue to run a bate and switch. We have investigated the matter on the internet and have found many others complaining of the same issue and ford's failure to take responsibility. Someone is going to get injured if they fail to correct their design defect.
Loud pop then loss of vehicle power, continual popping sounds until I stopped engine. Spark plug was ejected from engine. I believe this investigation should be reopened as this should be a defect recall .
