Spark plug problem 2002 F 250 NEED HELP!
The boot that blew up yesterday, got a motorcraft replacement.
The tall plug was in cylinder #6 on driver side and that adapter piece was threaded down. The plug (motorcraft) is for my year 2002.
The new plug will not thread into that adapter in the well. I had a tune up 4 years ago and the Champion plug is for 2005-2008. My 2002 uses the Motorcraft. The question I have is why is the long plug used? The threads are different. Do all sparkplug wells use the adapter shown on the left?
Looking for answers and some help on this?
Thanks,
PJ

That adapter and long plug are from a plug blowout kit, the long plug is needed to reach down through the adapter into the cylinder. It’s not the ideal or best blowout repair for sure. At this point I think that your best bet for a good reliable repair would be the Time-Sert kit and their oversized insert designed to fix prior failed repairs, which is what you have there.

Thank you WE3ZS for the reply!!! I'll look into it but will have to seat the current adapter in there as this is my only drive and doing any further alterations is something I'll have to plan for. I am guessing that one way to seat the adapter is to thread a longer bolt into the back end, get a few threads going into the well, start threading the spark plug or should I seat the adapter firmly before trying to thread the spark plug? First got to find the thread pitch for the back end (female) at the local ACE. If anyone has a different route, I'm all ears. Got to have it done by Friday, working this weekend.
Thanks,

I would thread the long plug back into the adapter then carefully try to get the plug adapter combo to start back into the plug hole and torque to 26/28 ft/lbs. Use that same torque range for all of the new plugs.
Good luck!
Good luck!

Has anyone done a Heli-coil to repair a worn out spark plug hole? What about Time-Cert? Is putting an adapter anchor (such as a Heli-coil) one of the only ways? How much would a mechanic charge to do one cylinder well? I got a price of $300 for a Mobil Mechanic to come by and perform the Heli-coil fix. My guess is that "re-tapping" this hole is not a good fix. Thoughts anyone.

Heli-coil is not a good option for this repair, the best options are from (possible spelling errors are on me….) Time-sert, Cal-Van and Lock -N-Stitch. I know for sure that Time-sert has an oversized insert designed especially for your situation, a failed prior repair, not sure if the other repair kits also have the oversized inserts too or not. That is if the adapter device you have that has the extra long spark plug has larger male threads than the correct plugs, if so that sketchy repair kit hogged the factory hole out to a larger size, that’s why I’ve mentioned the oversized repair insert, the standard size inserts are designed to go into unaltered factory holes.
