I once had to make a flat probe tool, with a lip, to slide between a gap, and then raise it and use the lip. To pull, I used a couple of old dinner knives, I bent the ends over a piece of hard edged steel in a vice, and filed the lip, to a very small size, the strength of the stainless, and usability of the handle was key to solving the problem.
If trying with long nosed pliers...I think, the stepped washer that's on the plug, you need to make sure you are grabbing the washer, and not the plug top.

Finally, after (if) you have drilled the b@stard thing, you must blow the crap out, as it will drop into engine. If you break the plug, those porcelain pieces, when plug is removed, drop in, and will never come out, and will damage the engine.

You could try to "wiggle" the washer or even bend it so you get more space around it. I'd suggest to do some wiggling first, left right, left right to see if it come loose. Next try to bend one side down to you can hook underneath, then bend the other side down and another hook underneath.

If it is very tight, I doubt the Araldite will work. If it is not tight, the air or water may work (especially if you use a Karcher with the rotating water nozzle).

The more I think about the welding rod idea, the more I don't like it to be honest.

The self tapper trick could work.

Another more "destructive" method is actually destroying the porcelain part, this would loosen the washer and after having blown all the shards out of the hole, the plug can be removed as the socket goes over the steel part . The only risk is that the porcelain cracks all the way through of course and ends up in the cylinder. So if you are desperate than you could try this, but only try to break the porcelain inside the washer, by using a pick (priem) or something like that or a centerpoint. Actually the wiggling and/or bending trick above are likely to break the porcelain anyway come think of it. MY 2010 5.0 SC Galway green and sand interior!!

How did it go? In the end, what was the problem?

I found this thread because I was looking for posts on misfires. I'll be checking mine for oil tomorrow. I have new gaskets on hand.
