What causes spark plug to strip out?
- The threads may peel out if the spark plug is installed with too much force. When inserting a spark plug, it’s crucial to adhere to the manufacturer’s specified torque specifications.
- Stripped threads can also result from cross-threading, which happens when the spark plug is pressed into position despite not being correctly aligned with the cylinder head. This could occur if you install the spark plug carelessly and unintentionally apply sideways pressure that causes the spark plug to be out of alignment.
- The threads may strip out if a hot or seized spark plug is removed before it has had time to cool. The metal of spark plugs swells at high temperatures, making removal more challenging. Forcefully attempting to remove a hot or stuck spark plug can ruin its threads.
