Tl*the contact owns a 1999 ford f150. Within the last thirteen months, two different spark plugs have blown out of the cylinder head. Both the dealer and the extended warranty company stated that this is a common failure and is due to the casting of the cylinder head. The second failure occurred while driving 20 MPH. The current mileage is 99,979 and first failure mileage was 88,844. Updated 02/01/08
Tl*the contact owns a 1999 ford f-150. When coming to a stop at 20 MPH, the vehicle's engine shuts down. The current mileage is unknown and the failure mileage was 113,250.
Have a 1999 f150 that has a fix recorded for the head gasket, but has no recall. Even though ford knows there is a fault, and should take care of or repay the consumer for fixing, since ford knows there is a problem.
1999 ford f-150 spark plugs blowing out.
While driving to work at 5:30 am, a load noise came from the engine compartment. The truck would barely run and required a tow, the dealer ship said that the spark plug had ejected from the engine due to stripped threads in the block. Also I have complained about the truck losing oil and the smell of burned oil on an off since I purchased the truck in 2000. The dealership could never find a problem. The leak is now worse with oil on the garage floor for the past year and the smell of burned oil more often. I suspect the head gasket from reading other reports on the internet.
Blown head gasket.
Dt*: the contact stated the engine was leaking oil. The vehicle was taken to the service dealer who determined the engine's head gasket had a small chip causing an oil leak. To remedy the problem, the service dealer recommended a new head gasket to replace the defective one.
Truck started missing, sputtering, pinging, running on 3 cylinders. Valve spring broke in engine.
I purchased my '99 ford f-150 in the spring of '04. At the time of purchase the truck had just over 49,000 miles on it. This past monday (10/16/06) while pulling out of a local parking lot, the #2 spark plug was ejected out of the right cylinder head, ripping out the threads that the spark plug screws into & destroying the coil pack located directly above. My truck on the day of failure had 81,790 miles on it. That's 18,210 miles short if the trucks first manufactures suggested 100,000 mile tune-up. Ford will not even consider the thought of making this manufacturer's defect right. They simply told me that the head would need to be replaced at my expense and at the cost of $2,800.00 to $3,000.00. It's a design flaw!!! The aluminum heads for the 5.4 l engines were engineered with an inadequate number of threads needed to retain the spark plugs. There are only 4 to 5 threads tapped into these heads (approx. 1/4" to 5/16" in length) today is october 19th and I have purchased a repair kit manufactured by dorman products to fix this stripped out spark plug myself. This kit is specifically made by dorman not ford, to fix this problem of fords 5.4l engines. It's really sad that ford has to use the consumers as guinea pigs and then fail so miserably to back their product. I'm hesitant to check the torque of the other seven plugs in fear that they will not withstand the recommended 25 foot pounds of torque required to tighten them up but if I don't then it's russia roulette as to when the next one will blow out and where I will be stranded when it does. I expect ford to stand behind their product 110%, especially when it is a well known fact by ford and the consumer that there is an engineering flaw with the design of the 5.4l engines aluminum heads produced between years of 1997 through 2002.
I have a 99 f150 with less than 60k miles on it. While driving to work a spark plug blew out. Repair was not able to be done on the head. Head replacement was $3600 engine replacement was $5000. I replaced the engine with the same type of faulty engine... How long until it happens again??
99 ford f-150 197k miles. Cylinder #3 spark plug blow out. Almost broke fuel rail. No fire heads replaced. Seeking reimbursement from ford 3150.00.
My daughter was traveling on a high speed state highway when a spark plug blew out of the aluminum cylinder head of the 5.4 liter engine of her 99 ford f-150 xlt 4wd pickup. The truck was towed home. After numerous inquiries with ford customer relations I was rudely instructed not to contact them further. Her truck had 65,909 miles on it. I had it towed to the local ford dealer and paid them $3600 for the repairs and a new head assembly. I'm a retired auto technician with 50 years in the business, so, I consider myself knowledgeable. I know of 5 incidents with our customers suffering the same fate. One customer had a truck still under warranty that blew all 8 plugs out. All customers affected were towed to ford dealers by us. This condition could present a nasty accident on a super hi-way with possible loss of life.
Oil leak in head gasket due to manafacturing defect. I see many other owners have the same problem. Truck is out of warrenty and repair is very costly. Ford is aware of the problem but is not helping owners.
When I started my vehicle their was a loud popping noise, further investigation showed the #2 cylinder coil was jumping up and down. When I pulled the coil out the spark plug came with it. The aluminum engine head had stripped out the threads that hold the spark plug. Further dealing w/ ford dealership, as to how to fix the problem, is to replace the head at a cost of 2500.00 plus.
My ford f 150 blew the #3 spark plug out of the head on good friday. The truck lost power but was still drivable. The event occurred on I 39 north of madison wi. Had I not known what to do it may have resulted in an accident. Cost to fix this failure was 4200 dollars. Dealership replaced the entire cylinder head.
I never received a recall notice for ford recall#99b29. My address has not changed since I purchased the vehicle. My f150 has been using coolant and there are no signs of leaks. Now there is a loud engine tick at startup. All my miles are interstate miles, and the vehicle has been properly maintained and babied since purchase. What is ford going to do about this factory defect??
Spark plug blew out of engine causing engine head damage. This cost over $3000 to repair and I understand may happen again at any time with any of the 8 spark plugs.
1999 ford f-150 with a 5.4l triton v8 engine... Problem: blown spark plug after work, while accelerating onto the freeway, the engine made a "pop" noise, and then began to sound like a steam engine. The engine was running rough and loud, thus I pulled over on the side of the road. I was concerned that I may have blown a spark plug (or possibly a valve) and didn't want to set the engine on fire. I was stranded until I could get roadside assistance. Dealer claims that the entire head needs to be replaced for the blown spark plug with a newly designed head. Other options include to retread the blown spark plug. Seems like a design flaw based on the large number of other users w/ the same problem.
Was driving the truck home, about a mile out after being on the highway, there was a loud bang. The spark plug had been shot out of it's place, per a shop owner. Not sure why it happened yet. It was stated to us that ford has many complaints of this happening to their trucks. We have a 99 f150 and wondering if there are more such complaints and if so what can we do to push the issue. It could get someone hurt at some point!
Spark plug blew off when I turned my truck on. Ford recommends new engine because apparently it happens often. There is currently no recall for this problem. Truck needs repair.
I have had different two spark plugs blow out of the head at different times. A heli coil was used to fix the problem.
I was driving to work and heard loud bang in engine. Found out spark plug had blown. No accident caused. I have two ford vehicles and the both had spark plugs blow within the last month. Both enignes are 5.4 l.
Leaking head gasket @ 101k miles. Antifreeze in #6 cylinder.
Dt: on september 23, 2005 had a spark plug blow out of the cylinder head of the vehicle. This was the spark plug on passenger's side, nearest to firewall. This was the third coil that the consumer had, but this it was the first time the spark plug came out. Contacted the dealer, they towed it. There was no forewarning. At 65 MPH, the consumer heard a pop and thought it was the tire, but it kept popping until vehicle stopped. The consumer exited the vehicle and discovered it was not the tire. Raised the hood and could see it flapping. No lights in dashboard came on and gauges did not move. *ak
I was driving my family down a winding major mountain highway in my 1999 ford f150 truck (5.4l v-8, 117400 mileage) when a loud bang came from the engine area and my truck lost power. This startled me and I lost momentary control of the truck. I regained control and pulled to the road side. The next day (10/3/05) I took the truck to fairway ford service department. They had replaced all the spark plugs about 10,000 miles previously. They determined the problem to be a "blown out spark plug". Both the service advisor and the service manager said the problem was caused by a bad design by ford (not enough threads to hold the plug) and the previous plug replacement had nothing to no with problem. They said neither they nor ford would take any responsibility for the problem they corrected the problem by installing a remanufactured left side cylinder head, all per a ford technical service bulletin. The cost was $2549.35. They kept the old parts.
I have a 1999 ford f150 with just over 60,000 miles on it. It has been maintained very well and has had no problems until now. While driving to work on 9/20/05, my engine sounded like it blew up. What actually happened was my #3 cylinder spark plug blew out. Thankfully it did not cause an accident. After investigating how to fix the problem I learned this was becoming very common with ford triton motors and would cost appx $3000 to repair. Ford offered no help other then for me to bring it in for the expensive repair, with no guarantee it would not happen again. I thought the truck would last much longer then 60k miles and feel like I bought a lemon.
Spark plug pulled out of the motor. The cost was great. It is my understanding that ford knows of the problem and did not notify the vehicle owners of the issue. It is also my understanding that if the spark plugs had been changed this problem would not have occurred. The plug pulled out at 81,000 miles. The plug changes are recommended at 100,000 miles. This procedure cost me well over $3000.00. If ford had notified me, and I had gotten the plugs changed the cost would have been considerably less that $1000.00. I was informed by the dealer ship that this could have caused a fire. As soon as the noise was heard I shut the truck engine off. This is a very dangerous condition that should be taken care of. I feel that ford should reimburse all the vehicle owners for the cost of this design issue.
While driving on the highway a spark plug ejected from the right side cylinder head of my 1999 ford f150 triton v8 truck at 56,978 miles. Cylinder head was replaced at ford dealership at a total cost of $2,418.93. I was notified this was not covered by the manufacturer.
