A couple of years ago, #2 cylinder blew the spark plug out. This cylinder was repaired using a thread insert. The car had approx 130,000 miles on it. Today, no warning, again, blew out another spark plug, this time #3 cylinder. Going to attempt repair using same type of insert. Plugs have been replaced one time, were properly torqued per Ford specs, the problem, in my opinion is a defective design of the cylinder head where there are only approximately 3 threads in the aluminum head that actually grip the plug or about 1/16'th of an inch, where the plug has nearly 3/4 inch of thread. Naturally, Ford won;T do anyting to help, but there are literally thousands of cases like this, some of which have resulted in fires, and even the aftermarket heads by trick flow address the problem by fully threading the spark plug holes in the heads.

Spark plug blew out of cylinder #6 and ruined coil-on-plug along with it. I had to take it to a mechanic and they used a time-sert kit to rethread the cylinder spark plug wall and replaced all plugs with factory plugs. I replaced the spark plugs myself 6 months before the incident using aftermarket plugs and it ran fine for about 5,000 miles until a plug blew out....updated 09/22/15 updated 10/13/2015

Threw a spark plug on interstate. Had to have it towed to nearest Ford dealer and repairs were over $400 plus a rental car to get home. I understand this is a problem with Ford engines. Not good for older peopl traveling alone and out of town by 3 hours. This needs to be fixed.

The engine light came on the dash and the car started to slow and sputter as like it was out of gas, when I had my mechanic look he found the intake to the manifold was shattered ( the plastic part that the hoes grips onto. I was coming home from work it was cold and the car just stops working as the loss of the fluid from the intake sprayed all over the motor, belt, hood, electrical and the motor locked up as I was trying to cost to the pull off as it was a major traffic area. The manifold intake broke !!! in New York "

I was on vacation coming home and the car started to pull then let go and the engine light cam on then car locked up on the high way few seconds latter their was thick white smoke coming from the hood of the car and threw the vents inside the car. I turned the hazard lights on and got out of the car on a heavy high way the car smoked for about 20-40 minutes, after it faded I opened the hood to find the ( manifold intake ) broke spraying the coolant all over the engine and electrical under the hood of the car. I see online their has been other complaints and Ford fixing them only in the hotter states as I live in NY but was in Texas when this happened. Also when this happened I had no place to pull off the road as I was in congested traffic / busy highway - I am lucky I didn't get hit by a car. Ford Motor Company I know you know of the issue !!!
