Re: Sparkplug thread/aluminum heads-TRITON MOTORS
I'm in a bunch of Ford F-150 forums and the problem is with the 2004 and up 3v heads and the spark plugs in them. The 2003 and earlier heads are 2v and not without problems be it a lot less than blowing out the plugs should be changed at around 30k and a little bit of anti-sieze put on the threads of the new plugs prior to installation. Torque to factory specs and no more. For engines over that mileage they suggest very careful removal using Ford's penetrating oil. Replace with a good platinum spark plug and
