One of my super duties a 1999 F250, approximately 275,000 kilometres with a V10 blew a spark plug, in the process it took the threads with it and ruined the head. Is this a common occurance? The only problem with the engine in the past is one of the wires going to a plug has gone bad. Just looking for comments and any info would be appreciated.
Thanks!

Don't know what reported here, so look for updates. However, while on another site back in 2K, some reports on spark plugs blowing. As I recall both 5.4L & V10.
Few reports I saw had ALOT less mileage. As I recall there was some connection with how many threads the alumn. heads had & did they really hold the spark plug securely enough. Expansion/contration, alumn VS metal etc, really got technical & over my head. There was a repair kit for the stripped out hole. Dont recall kit, but seemed some success, short of $$$ for new head.
As I recall the new (03?) 3 valve 5.4L triton got redesigned heads. Don't recall if same on V10, but suspect same done. Anyhow, seems you got good service, but still a bummer. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
I've heard several reasons for the plugs blowing out. #1. Spark plugs were changed using other than Motorcraft. Chamfer on plug that seats to aluminum head not the correct angle. #2. Plug hole was not blown clean with compressed air. Dirt/sand between plug seat and head prevented proper torque. #3. Improper torque on spark plug. #4. Water seeped past the coil pack and filled the plug cavity. The addition of water and the dis-similar metals contraction rates caused plug to loosen. Pick one. Your guess is as good as mine.
Thanks for your thoughts, the truck has always had its spark plugs changed at the dealer. The truck is a service truck in a logging business, I am sure there is lots of opportunity to get dust and maybe some water around the plugs. I have another 99 F350 with a 5.4 with close to 400,000 kilometres, the only major issues with it has been has been a few head gaskets and a couple manifolds. Yes I do get good service out of my Ford trucks!

lisle tool co out of clarinda iowa makes a repair kit to fix the threads--and dont have to remove the head!!!! dont know the price of the kit--but it aint a five minute job either--but sure beats pulling the head!!!!!

Thanks, I am printing off to show the service department. I plan to put a rebuilt head on it as I need to get the truck back on the road asap, as it goes 7 days a week.

Ford specifically says no heli-coils. Head replacement only. Also the AGSF plugs MUST be used. They are different than the AWSF's that came from the factory, and won't vacate the premises like the AWSF's.

Yes, they don't recommend the heli coil, I discussed this with the service manager and Ford says it won't hold and if it lets go it could end up with pieces going inside the engine. I appreciate the comments and suggestions, this was what I was looking for. The truck has been back on the road since Weds. Thanks!

After having replaced the damaged head with a rebuilt and then seeing the cost, I think the next time I will try a Time-Sert. My reasoning would be, with such high mileage on the engines, I will take my chances. If the insert didn't hold and ruined the engine I would replace it with a used engine.
Again thanks for the comments!

I have a friend that rebuilds motor cycle heads and this is the only product that stays put.

TIME-SERT is a great repair! here is a link for ford heads.
I did the repair on my 5.4L head i took my time and
had it fixed on the weekend. It was well worth it.
The dealer wanted $3000 to replace the head! for
one bad sparkplug hole. p/n 5553 http://www.timesert.com/html/triton_repair.html www.timesert.com
