A D V E R T I S E M E N T S

On the day listed below my 1999 Ford F150 with a Triton 5.4L V8 engine ejected a spark plug from the cylinder head. Upon inspection by a mechanic it was determined that the threads in the cylinder head failed. The compression in the cylinder then ejected the spark plug. After the spark plug was ejected and before I could get stopped there was a strong smell of gas in the cab of the truck. Which I assume was caused by the open cylinder and fuel being expressed through the spark plug opening.
