Its done. Except for being a pia to reach, not too dificult.Took me, a rank newbie 2 hours.Things I would recomend for anyone else doing this, get both a 12 and 8mm racheting box end wrench. I had a 12, but no 8, and the 8 would have sped the whole process up, especialy for the bugger behind the oil filter. Get extra nuts for the wire connection, they are very easy to drop and loose. I had no trouble getting the old ones out. I don't know if it helped, but I had been spraying them with penetrating oil several times over the last 3-4 days. As an aside, they had basically no carbon build up. I didn't ream anything, as there was really nothing to ream. The old plugs had erroded tips, but were really clean. I have put about 13,000 miles on this car since I bought it, running biodiesel the whole time. B100 when warm, running B50 through the winter. I was amazed at how clean they were for a motor with 223,000 miles on it.
Again, thanks for the help.
