Ok finished all 6 plugs. #4 was a B#tch. #6 took 5 mins.
Somehow #4 broke on me, and 2 pieces of the cermic/porcelein - whatever material it is - fell into the plug hole. FML. Seriously. Used a vacuum and some little pipe I had laying around and played a game of fish the broken pieces out of the cylinder head. Got them all.
I would never wanna do this job sober ever again.
