Ford F-250 Super Duty Problem Report

Ford F-250 Super Duty One or More Spark Plugs May be Ejectioned From the Cylinder Head

(32 reports)

There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

Just today 12/15/13 driving 30 MPH. It is the first cylinder on the passenger side. #? I've read this is a extremly common problem, and I don't have the funds for repair. No longer a Ford enthuiast. Brian -
Started my vehicle today, 12/15/2012, at the mall and..boom!! then some smell of smoke inside the vehicle ...then more popping which sounded almost like a belt slapping against something under the hood. I had no prior indication of a problem except yesterday morning there was a vibration in the steering wheel while accelerating that stopped once letting off the gas. It did smooth out within 45-60 seconds and did not reoccur. Then today's issue occurred. I had the truck, F-250, 2003 Quad Cab, with 150-K miles towed to the Ford dealership about a mile away which was the place of original purchase. Initial estimate to repair it..$700.00; not a happy christmas gift -

Two plugs blow out on the passenger side within a year and now I feel like its happeneing again. Same kinda before symptoms. But me and my dad replaced both with a helia coil ( however you spell it) I think there was one other part but ordered from Napa amd was only 75 bucks or so. The first one was a pain. 4th one on the passenger side and was under all the other hoses and such and took 3 hours. Second one was just infront of that 3rd one back on passenger side and only took 20 mims without all the stuff in the way. Hopeing the one that is going bad now is a different on so I dont have to get a whole new head if the ones I already fixd blow out again. -

front plug on the passenger side of the engine. Fixed by the guys at blownoutsparkplug.com. They did a great job and are very knowleagable of this problem. They changed all the spark plugs with new ones and checked all the other cylinders for potential problems. Have not had any problems since. -
#6 sparkplug blown out. Not yet repaired. -
#5 blew out, it also destroyed the ignition coil The best repair is to remove both heads and have a machine shop install new inserts I have heard (but not seen) that some of the inserts installed with the engine still assembled have failed, this is most likely due to lack of room and access in the engine compartment -
