problem #3

Apr 242009

F-150 Lightning 5.4L Supercharged

  • Automatic transmission
  • 61,000 miles


3 spark plug blew out of head and ruined coil when it exited the head. Ford dealer stated it was a known problem but Ford wouldn't issue a recall. Found website named blownoutsparkplug.com and flew their tech out to where the vehicle was and it was repaired where it sat. The owners of this niche business are Ric and Dave Mahlmeister based out of Southern California. It took Dave a little over 2 hours to fix the head, replace spark plugs and inspect all spark plug threads. The fix is guaranteed. Cost for this fix is 800.00 plus airfare and expenses if overnight stay is involved. This figure includes up to 2 thread replacement inserts, new spark plugs and new coil. I highly recommend this website in lieu of paying Ford 4K to pull the engine and replace the head, which is what is recommended by Ford.

F-150 XLT 4.6L V8 Triton

  • Automatic transmission
  • 90,000 miles

Blew spark plug from cylinder head. Out of truck for awhile. Did internet search. Lots of similar complaints. Problem has even spawned businesses to address the repairs. That tells me alot. I asked a 25-year Ford tech about it. He admitted to the problem. Ford doesn't admit to anything.

F-150 Supercrew 4x4 5.4L V8

  • Automatic transmission
  • 85,000 miles

I have an 02 F-150 with the 5.4L V8 (modular) and have blown 2 spark plugs out of the motor. This is a problem that Ford has recognized and actually approved a company's product to use (www.fulltorque.com) for repairing the problem, but will not recall as a defect. I have spent $2200 in parts and labor (doing the absolute minimum) and I can hear another spark plug about to go. This has been a real pain in the ass.
