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.

6.8 litre v-10 engine and one spark plug from each cylinder head came out. One cyl head had threads destoyed thereby making a replacement nessesary and the other one was suspect. The dealer suggested a rebuilt engine as costs would be very close between repairs and a genuine ford rebuilt engine and it would come with a warrenty. My complaint is that the plugs came out because the cyl heads were a poor design with only 3/8" threads in an aluminum casting and I shouldn't be paying for poor engineering and designs. There has been an update in 2001 that now has a cyl head with 9/16" threads and plugs to suit. I want ford to install a new updated engine at their cost.

There is a common problem with the right side head gasket in 5.4l v8 engines in vehicles from 1999. This problem results in a blown head gasket that requires repair at great expense. In addition the repair that is approved by ford is not permanent, so the vehicle many times has the same problem multiple times. I personally have a vehicle with this problem and have several friends with the same problem. I believe that ford needs to issue a recall for this problem and fix it right so that recurrences do not happen.
