  1. Anyone have opinions on the best stuff to initially loosen the 'stuck' plugs on a 4.6L 3-valve. I was considering either PBBlaster or Aerokroil. Some say regular carb cleaner, but there must be something better.:shrug:
     
  2. PB blaster worked for me.
     
  3. PB Blaster did the trick for me too.
     
  4. Ive heard rumors Ford has something they use. Spray down in there before they begin. Probably very similar to PB.
