Planning on doing my spark plugs soon...advice please.
I know of the TSB stating that there is a chance of busting one or more spark plugs upon removal.
I am just curious, what is the percentage of this happeneing and would it be OK to soak the plugs over night in the penetrating oil after I break them free?

Once you break them free, you might as well just pull them. The initial break is where they are gonna snap. Soak before the break and you might stand a chance. Use good quality tools also. Good spark plug socket with an insulator, long handle ratchet so you can break them slowly.

I thought I just read that its not the initial "break-free" that busts them, rather the turning afterwards if they require more than 35lbs.

just make sure when making that initial turn to break them free...and lemme tell you ford put them on there TIGHT...to make sure the tool isnt leaning left or right. i found that as long as it was as straight as can be, there was no chance of breaking the plugs. good luck man

Lot's of threads on the plugs in search. Besides the TSB, they also came out with 1 piece plugs to replace the problematic 2 piecers.

Post #37 has the TSB as an attachment:

I followed the FORD TSB that calls for cold motor, 1/8 turn, stop, carb cleaner soak, ( Ford says 15 minutes, me, 90 minutes), torque wrench up to 30 ft lbs., and slow and easy. 6 came out smoothly, and two squeeked and groaned at 40-50 ft.lbs all the way but they are out and I fell to my knees! All of these plugs had a lot of carbon on the barrels.
Also, the Motorcraft plugs are a 9/16 socket, the Champions are a 5/8 socket so watch out AGAIN!
Anti-seize on all of the Champions threads and in they went at 30 Ft Lbs.

I did mine @170K. All plugs on the left bank came out, all on the right bank broke.
You will need this tool by Lisle, works great!!

I just did my '06 with 60k miles and had two of them break. The Lisle tool works very well, took me about 15 minutes to get them both out! I knew right away when the ones that broke had broken. Follow the TSB but wait much longer than it suggests. Pre-order the tool or make sure you have a back-up car just in case.

I've got eight Brisk Racing one-piece plugs sitting on my workbench, just haven't had the ***** to install them. I'm ordering the Lisle tool just for piece of mind.
I know the TSB says to soak the plugs for 15 minutes, but would overnight hurt? I could soak them fairly well next Friday night and pull them on Saturday morning...
