I bought my truck in August, 2013. This is the 2nd time a spark plug blew! This sucks! With all the complaints out there about this problem, Ford really needs to do a recall. My truck is at the shop now, not sure how much they will suck out of me.

Expedition XLT 5.4L V8

  • Automatic transmission
  • 62,979 miles


the cost of this fix should have been around 700.00 (or under) for a HELICOIL - they (FORD DEALERSHIP) did the "while we are in there" approach and charged for everything - without asking - just "we have to" 1973.86 (almost triple)

Now 3-1/2 years later the same cylinder (I'm guessing #3) blows the spark plug - stripping the threads again - and I am responsible for the repair (3600.00 +tax) ABOUT $4000.00 for a new cylinder head and "while we are in there" Please post yours also so we get SOMETHING out of this - Thanks

I have a 1999 Ford Expedition Eddie Bauer Edition, While driving with my wife, all of sudden I heard this loud pop sound came from the engine, followed by loud rat-tat-tat

sound. got so scared i immediately pulled over, investigate what happen i notice the spark cable was hanging and split in 3 pieces and the spark plug was just sitting on top of the engine, it was very upsetting because i never heard such a thing, i had it towed to local Ford dealer and the service manager told me that this a common problem on Ford, that the spark plug will blow out, due to ford's poor engine design. While ford is blaming

the dealership technician from over torquing of the new plugs, the dealership on the other hand i s blaming Ford Company for their poor engine design, for the mean time we are the one who got stock paying for this outrageous charges. This repair had cost me $2644.53, i know others pay way more than this. Ford Company should realized that this problem is due to engine poor design, with so many complaint documented all over the Nation, Ford company should stop blaming others, and the Federal Government should step up to help the consumer resolved this problem, because this could be an emission problem.

Once again I have had another spark plug ejected from my cylinder head. I am furious that Ford knows they have a problem, but because of the expense involved in replacing both heads they choose to let consumers bear the burden of their poor design. This is unconscionable situation and a telling position which shows how committed Ford is to their customers.

spark plug blew out, sheared off the coil on top of it. spark plug repair kit would have been easy to use if the spark plug hole wasn't so dang deep. hard to get tools in there
