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

on trip from Dallas to Kentucky the engine blew #7 spark plug out while my daughter was driving, freaking her out.

The dealer also found that the number 5 spark plug was leaking and ready to blow.

Dealer inserted heil coils and replaced the #5 & 8 plugs along with the coils.

The is the third time this year that spark plugs have been blown out of the engine.

Expedition 5.4L

  • Automatic transmission
  • 124,460 miles

On my way home from Kansas to Colorado after enjoying some leave time before I deploy to Afghanistan. Got 100 miles from home heard a loud pop and then a sound like a flat tire but it wasn't. The spark plug had blown out of the head, stripped the threads and broke the coil. Had my wife 3 kids and 2 dogs, what a good time.

Expedition Eddie Bauer 5.4L

  • Automatic transmission
  • 145,000 miles

3 spark plug blew out damaging the coil. I have read that this is a common problem with the 5.4l triton engines. If this is so common why not recall the engine and give the people that still have some faith with fords a break. I took it to the ford garage and they gave me 3 options 1. heeley coil it, but they will not guarantee the work.

2. Buy a new head and that will cost me $3000.

3. Buy a new motor and that will cost me $6000. I don't know about everyone else but I think someone is getting screwed!
