problem #7

Apr 252012

F-150 5.4L

  • Automatic transmission
  • 53,000 miles


My truck is a 05 ford f-150 4+4 with 53,000 miles. The spark plug broke off and went down in the motor causing the motor to lock up. It cost me 6,400 dollars to fix it. Ford would not do anything to help me. It had the same plugs in it that came with the truck.I am 52 years old and this has hurt me very bad. I will never buy another ford of any kind. nor will any of my family or friends and I will tell everyone I see about this. I hope ford gives their CEO's a big raise this year. My family will not have a christmas Thanks To FORD.

F-150 4.6L V8

  • Automatic transmission
  • 78,968 miles

I had just purchased this used truck and had put only 1700 miles on it, when the #3 spark plug blew out causing two gas explosions when I was 800 miles from home. It cost $981.98 towing and repair to a Ford garage. I had them install a spark plug insert instead of replacing the cylinder head at a cost of $3,900.00. Before the spark plug blew out I did smell gasoline around the engine a few times and I checked but found nothing.

I found that Ford does not cover this known problem out of warranty.

Ford recommendation is to replace the cylinder head. Ford has a service bulletin

TSB 07-21-2 to install a spark plug insert.

The spark plug blow out is a design defect by Ford of the aluminum cylinder head and should be covered by extended warranty especially since there is a potential of fire and explosion hazard. The owners manual states the spark plugs should be replaced at 100,000 miles. My spark plugs were OEM at only 79,000.

After Internet search seems like the Triton 4.6 V8 of this model is notorious for blowing the plug.Should have been recalled and fixed.Plug blows and strips the cylinder.

never replaced spark plugs because ran great and fuel mileage was real good.Spark plugs should not come loose ,no matter how many miles .when they are installed at the factory.Ford should be responsible.
