Engine Knocking Noise problems of the 1999 Ford Expedition



Three problems related to engine knocking noise have been reported for the 1999 Ford Expedition.

car   Engine Knocking Noise problem 1
Failure Date: 01/09/2009

Was driving car to work this morning. Made a right hand turn and heard a knocking noise suddenly after completing turn. Pulled to side of road and immediately shut down vehicle. After shutting down I smelled what appeared to be gasoline. Called my insurance company and they had vehicle towed to Ford dealership. After waiting a few hours they told me spark plug had popped out and cylinder head needed to be fixed along with plug, and it was indeed gasoline I smelled. They said it would need major repair to fix, and tried to convince me to pay and arm and a leg. I don't care about that, I care that my child could have been in car, as I pick her up every day from school. Also mad that a fire could have started and Ford does nothing about this problem and that there have been thousands of complaints from Ford truck owners with Expeditions and f150's from 97-02. Something better be done to recall these faulty engine components, or families will suffer from Ford's lack of safety with these plugs and cylinder heads/coils.

car   Engine Knocking Noise problem 2
Failure Date: 08/25/2004

While I was driving on the expressway at expressway speeds all of a sudden there was a pop sound and the vehicle lost power and started vibrating badly. When got vehicle to mechanic by tow truck because vehicle had no power, it was revealed to me that the spark plug was blown out the head of the motor. It was the 3rd plug on the passenger side. My vehicle has a complete extended warranty but the warranty company claims that this is due to a loose spark plug. They are the original factory plugs supposedly you don't have to touch them for 100,000 miles. My mechanic states that this happened due to a defect in the head because he not only spoke to Ford mechanics but has seen this before. This is a common problem, upon researching this myself I found many other people on the internet with this same problem,at the same exact site on the motor. This is a problem with the head of the motor and my warranty company should fix my truck because this is a covered item it is the engine block that malfunctioned , not the spark plug!!!! please help because this is a very costly repair.

Engine hesitates. Dealer was not able to locate problem or provide remedy. Also, vehicle had an oil leak, and knocking noise. Dealer replaced head gasket, but problem is reoccurring.
