Yesterday I attempted the spark plug change on my 05, 5.4 3V and didn't break any plugs until I got to this one. I used the pusher tool from lisle, but I think part of the electrode is keeping the extractor from being able to grab in the tip. Has anyone encountered this before? any suggestions would be awesome! Thanks,
Can't tell from your photo exactly what is left behind, but most people who have trouble with the Lisle tool are not screwing it tool down tight enough or tightening the extractor insert in tight enough.
First of all do not panic...I would suggest using the first tool all over again and screwing down till it hits the bottom. then proceed to use the second tool until you start hearing things about 4 or 5 turns more then back out..youll be fine
@bigcanoe , IMO, there is a second (and I believe better) solution - more frequent changes AND clean the carbon build up out of the spark plug holes as part of the change procedure, with EITHER one or two piece plugs. This will also solve the spark plug heat range degradation problem resulting from the carbon buildup contacting the barrel. Which I believe contributes to the development of misfire problems in the 5.4L. See links:
IMO, the two problems - plugs breaking off - and misfires - are linked because if the carbon accumulation becomes serious enough to "twist off" the barrel, then forcing a new plug into that environment can "fracture" the porcelain in the new plug - AND - the heat conductivity of the carbon build-up into the water jackets degrades the "heat range" of the new plug.

Ya I wondered about that myself. Could you use some sort of bottle brush or something similar used when washing dishes
Harbor Freight has a set of brass & stainless "thread cleaning" brushes for just under $20.00. Comes with a "T" handle.
If you do this - use extreme care not to drop the brush into the cylinder like this fellow. http://www.ford-trucks.com/forums/13...lp-piease.html
I remove ALL my plugs first, then rotate the engine to bring each piston to TDC while I burnish that hole. But since I started doing this every 50k mi (two plug changes now), I have had ZERO misfires and > 200k on the clock. The last plug change - NO broken plugs.

Broken Spark Plug Question
ANTI-SIEZE doesn't make subsequent plug remover easier
A Better Solution
