Blown out spark plug from 2001 Ford Expedition triton 4. 6l engine during operation on a public road. The second spark plug on the passenger side blew out of the engine while it was being driven on the road. This made a loud "bang" sound as if a tire blew out. The loud sound continued like a loud exhaust leak and gasoline vapors were immediately present in the passenger compartment. The driver shut off the engine to prevent an engine fire after attempting to safely park on the side of the road while avoiding moving traffic. This required aggressive maneuvering to avoid moving traffic. The car is now awaiting repairs, which is est. At >$3,000. The mechanic reported that this is a very common problem on Ford vehicles with the triton engine. I have never before seen a spark plug "blown" out of the socket like this. The plugs were replaced once at about 50k miles. The engine has about 110k miles today.
2001 Ford Expedition 5. 4 v8 triton engine keeps blowing out spark plugs. This happened 2 months ago for the 1st time. I replaced the spark plug. 1 month after that, the same spark plug blew again with my wife and two kids. Once again I fixed it. Then 2 weeks later, the same thing happened again while I was out of town, and this time it took the threads with it. Now I am looking at spending $1,000. 00 + to fix it.
2001 Ford Expedition 5. 4l for about 2 weeks it sounded like there was an exhaust leak. Had an appointment to have exhaust looked at on 9/6/05. Coming home from work on 9/2/05, was stuck in slow traffic. When traffic broke up, I started to accelerate and heard a pop and lost power. I had to get over 3 lanes of traffic to pull over. The truck was making a loud noise and smelled gas. Had to call a tow truck to pick it up. It cost me $200 to have it towed home. On 9/6 I called the dealership that had worked on it last and they pretty much told me that did not want to look at it. So I called the local Ford dealer and they told me the same thing. So I had it towed to a local engine shop for repairs. They are pulling both heads and installing 8 new head certs, which cost me $2000.
Some kind of silvery white substance I powder, and sometimes pieces were coming out of air conditioner vent. Substance was making family ill when riding in vehicle. Contacted dealer ,and dealer inspected and replaced heater core and vacuum pad, but problem has come back. Please add VIN#.
