Broken, Cracked or Chipped Insulator
Spark Plug Inspection:
^
A chipped electrode insulator usually results from bending the center electrode while adjusting the
spark plug electrode gap.
^
Under certain conditions, severe detonation can also separate the insulator from the center electrode.
Spark plugs with this condition must be replaced.
