While driving my 1999 Ford Expedition 5. 4l on the interstate at 55 mph, a heard a noise which at first felt like something caught in the fan, but was alter determined that a spark plug #2 passenger side had blown out and broken off the coil causing contact with the 2 fuel rail. I have discovered that this is a common problem amongst Ford triton engine owners and the aluminum head is inadequate in keeping the spark plugs intact after 50, 00 miles or so due to a design defect. As I understand it, Ford has re-designed the head on newer models, but has not issued a recall for this defect. I feel that a recall is necessary because the coil can damage the fuel line and that could cause a fire in the engine compartment.
This vehicle has had three blown head gaskets within the first 40000 miles, vehicle hestitates during acceleration which produces a significant safety hazard at intersections.
Consumer took vehicle to dealer for engine gasket repair, and dealer said it would be 3 to 4 months before parts would be available. This is not a recall part.
I just purchased the 1999 Expedition 4. 6l XLT on March 4, 2003. The vehicle has approximately 38,000 miles on it, and I have only put about 500 on it since the date of purchase. I bought the vehicle in virginia and needed a maryland inspection. Upon the inspection, the mechanic noticed a leak around the engine. He did not investigate the issue, since it is not an inspection item. I am afraid that with all the other complaints about the right side head gasket, that this is in fact the problem. Will my limited power train warranty that the dealership gave me cover this cost. I think it is a complete shame that Ford has knowledge of this recurring problem but does not offer a solution. If there are any programs that Ford is offering, I would like to here about them.
