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.

Engine spark plug blow out at 80,000 miles on engine. Engine had 40,000 on it from new and was consuming oil due to the right head leaking oil. Ford replaced the head gasket. The gasket did not solve the problem so a new motor was installed. Now at 120,000 (80,000 on the motor) after the spark plugs were changed, a plug blew out of the head. A helicoil was installed after the plug blow out but that also failed. Rebuilt head is being installed. Feel this is a Ford problem on this spark plug blow out. The 5.4L head is not manufactured to withstand the horsepower.

While driving on the highway with my family my 6 year old Ford Expedition blew a spark plug right out of the head. It has come to my attention that this is an on going problem with this vehicle. We had been driving for about 5 hours coming home from a family vacation when this occurred in New Jersey. We were lucky in this case because we were able to make it across the highway and off the road. The problem completely destroyed the head on the left side of the engine and the vehicle was unusable for over two weeks while the local Ford dealer worked on the problem. That head had to be replaced as well as many other parts associated with this problem. The dealer stated that this could happen again with the head on the right side. Between the repairs to the engine and the rental car for the time of repair, this was a very expensive (5000 $) problem. Which I stated earlier appears to be an ongoing problem with this motor.

One spark plug on my 1999 Ford Expedition exploded and burst through the head of the engine. My wife was picking up my child at school. She parked the vehicle, shut it off and minutes later returned. As she was starting the Expedition both her and my daughter heard a very large explosion from the front of the vehicle. The vehicle continued to run and a constant popping sound could be heard. She immediately shut off the engine and noticed a very strong gas/exhaust type smell. She called me and I arrived to check the vehicle out. I inspected all the fluid levels and fuses and they were fine. I briefly started the engine with the hood open to help narrow the location of the sound. The sound was coming from the top of the engine on the passenger side. I started inspecting this area and found that the third spark plug from the front of the engine on the passenger side had been completely blown out of the head of the engine. It is very fortunate that this occurred in a parking lot. My wife and daughter were both very startled by the loud explosion and I can only imagine what would have happened if this had occurred on the road at a high rate of speed. I believe that an accident would have resulted. I have since done some research on this particular issue and have learned that this has happened on numerous occasions on Ford vehicles and has been brought to the attention of the NHTSA. I would like to file this complaint and find out what the NHTSA is doing about this specific issue. The design issue with this particular spark plug/engine head combination is well known in automotive circles. What is the NHTSA doing about this issue. Thank you for taking the time to hear my concerns, and to reiterate I believe that there would have been an accident if this event had happened on the road at any rate of high speed.

1999 Ford Expedition with 5.4 Triton V8. Spark plug is ejected from the aluminum cylindar head. Immediately upon the plug being "blown" from the position on the head I could smell fuel and the engine began to violently make a loud "popping" sound. I have found numerous complaints on the web regarding this but cannot find any resolution measures. Bought the truck used with 85K miles but I have read other complaints where the plugs blow out at much lower mileage. Had to have it towed because I was advised by the dealer that, "it wouldn't be a good idea to drive it if you smell fuel." I had the service rep tell me that, "this is pretty common in our lighting models with the V10, but not with our V8 models." He also tells me that the plugs were too short for the engine but I checked with the mechanic that changed my plugs and he says that he put the replacement spec plugs that Ford recommended. Links to other sites related to this: www.F150online.com/forums/showthread.php?S=&threadid=103042 I know these are not filed complaints with the NHTSA but this is a serious issue. When I took it into the Ford dealership at dobb's Ford, 7925 hwy 64, memphis, tn 38133-4007, they told me originally it would be $2600. I was almost set to have it done then he tells me that labor was not included in that price and the total price would be $3800.

Spark plug (believe it was #4) blew out of the cylinder head. 66K miles. These were original plugs, so not attributable to faulty mechanic. Head re-threaded, new plug inserted.

While driving to myrtle beach I heard a loud bang under the hood.I had the truck towed to a Ford dealer where they told me the spark plug blew out of the cylinder head.I have read many complaints about this issue on the internet. I feel this is a safety issue due to the strong smell of gasoline when this happens.Ford said they will do nothing and it will cost me $3600 to fix this. Who says even after replacing the head it wont happen again and again. I am disgusted with the whole thing. I think Ford should step up to the plate and fix this problem.

I have a 1999 Ford Expedition 5.4L engine, while drivung the vehicle one of the spark plugs blew out. I contacted Ford motor about the problem and they said there is nothing they can do. After doing some research, I found that alot of people have complained about the same problem. Ford motor knows they have a problem with this engine but woun't admit it. I think it is a big safety problem and Ford sure realize it. If you could do anything for me and unknown amount of other people that purchased this piece of junk please email me thanks
