Has anyone heard about a problem with 2000 X's, v10 models, and blowing the spark plug out (and thereby causing the coil to break?) I had this happen recently, and the dealer made no mention of it being a problem with the X's, but I just saw a discussion on the old fordexcursion.com website talking about the exact same thing that happened to me.

Yes it happens.

Visist the V10 forum at www.ford-trucks.com. It has been discussed many times.

Sorry for the back luck.

hmmmm, I see he moved to "The Big Island", sounds nice!!!

Anyway, I haven't found any info on the other groups about the spark plug problem, does anyone know where I can find out more about that problem?

Yes, Nick. I moved!

Actually my wife and kids are still in Gardner until June 3rd. Then we will all be here on the Big Island of Hawaii.

I know that there is a lot of info on the sparkplug issue at ford-trucks.com. I mean lots. However...none of it has a magic bullet to prevent blowouts other than replacement of plugs prior to the 100K and to include sparkplug torque-down in a regular maintentance schedule. Say maybe ever 30K

83° Light trade winds. Surf on the West side (Kona side) was 2-4 feet. Just another perfect day.

Sounds nice. Just an FYI for you now on the Boston weather: "The Usual", partly sunny, partly cloudy, some rain - some sun, cold this morning, hazy, muggy and humid. Another unpredictable NE day.

Nick, yes, it's a known problem on the Ford 2-valve modular engines, and the 6.8 V10 in your 2000 is one of them. For anyone who lands here from a search, the document to ask for is Ford TSB 07-21-2. It covers some 1997-2008 vehicles with the 4.6L 2V, 5.4L 2V or 6.8L 2V engine and aluminum heads whose spark plug port has stripped or missing threads, and it gives the repair procedure. It replaced an earlier bulletin, 07-15-2. Note that it says the repair is not covered under the new vehicle warranty, so most owners pay for it.

The root cause is that these heads don't have many threads holding each plug. If a plug works loose, it strips what threads there are and blows out, and it usually takes the coil-on-plug coil with it, which is exactly what happened to you.

The good news is the head doesn't have to come off. The bulletin lets a shop cut the hole and install a thread insert with the head on the engine. One kit approved for this repair is the Lock-N-Stitch Full-Torque insert kit. Ask whoever does the repair which insert they're using and get it in writing.

To keep the other nine plugs where they belong: only pull plugs on a fully cold engine, and torque them to the factory spec with a torque wrench rather than by feel. If you have the plugs out anyway, a shop can check each port's threads at the same time.
