Another guy at the shop got scared after he couldn't budge any of the plugs on this car so I got it hot and they came right out.Basic physics dictates that the hole gets bigger when the metal expands due to heat.Aluminum expands at a much higher rate than the steel of the spark plugs.I never use any air tools on spark plugs.Same guy who couldn't budge the spark plugs ended up wrecking this one last week.Working in this shop is like trying to take fields with the knights.(Image removed from quote.)
Icepac I very rarely cracked one either until Ford came out with a piece of poo.... in the pic I posted below, from the plug seat down breaks off and gets stuck in the head due to the carbon build up. I have broken them in new truck with less than 1k on them before anyone even knew there would be a problem with the design of them and before they made extractors to get the broken ones out. so in other words I had to remove the head get the plug out put it back together so I could do the compression test to find a bad valve seat on the opposite bank and remove that head. Now I know what you are going to say, "why did I not pull both heads off wile I was there" but.......it's the Ford way of doing things by the "BOOK" that bites me in the A.r.s.e every time, Ford tech was involved since it was the first few months of the 3v and it had to be don their way.http://www.google.com/imgres?imgurl=http://www.allfordmustangs.com/forums/attachments/2005-2010-mustang-gt-tech/40272-2005-mustang-gt-4-6l-3v-substitute-spark-plugs-champion1.jpg&imgrefurl=http://www.allfordmustangs.com/forums/2005-2010-mustang-gt-tech/106448-2005-mustang-gt-4-6l-3v-substitute-spark-plugs.html&h=480&w=320&sz=27&tbnid=lYxthwFVWamh9M:&tbnh=90&tbnw=60&zoom=1&usg=__F3eoVTwxG0zSMp2gWpMm3FBze50=&docid=xXWDKf2nPouEcM&sa=X&ei=p8EOUt6cBYKRygGT_YAw&ved=0CEgQ9QEwBQ&dur=676#imgdii=lYxthwFVWamh9M%3A%3BqWd0d3H56PFFGM%3BlYxthwFVWamh9M%3A
