Why are the tips of my spark plugs cracking?
If the auto-ignition/thermal overload is bad enough, you can end up with simultaneous damage to the center electrode and ground electrode (s), and sometimes you end up with soft/spongy/cracked insulator tips (the white part). If it’s just the ground electrode that is eroded, for causes they point to: Aggressive fuel and oil additives.
Why did my spark plug electrode break off?
The guys at the machine shops acted like a spark plug electrode breaking off is just one of those things that could happen to anyone, just bad luck. …just bad luck.. OR whoever put the plugs in kept bending the electrode back and forth trying to get the proper gap and fractured the metal.
What causes spark plugs to get stuck in cylinder head?

Can a spark plug go out of an engine?
simply went out the exhaust if the wastegate wasn’t directing exhaust to the turbocharger. No question – running the engine will break it. If you’re “unlucky”, there’s enough clearance between the piston and the valves to fit the spark plug. In that case you’ll have the spark plug rattling around inside the cylinder.
What causes a spark plug to break in an engine?
The plug that broke was a Bosch Platinum that had only been in the engine about 20,000 miles. Has anyone else had this happen or heard of it? I am concerned that there is something wrong with my engine that caused the electrode to break, or do spark plug sometimes break like this for no reason?
What to do if your spark plug broke off?
Finally there are stories of this condition (missing ground electrode) occurring often with Subaru vehicles. The owners remove all of the plugs, throughly clean the threads and clean out the bores, replace the plugs and plug wires, and the problem goes away.

Why are the tips of my spark plugs melting?
Spark plug tips are breaking/melting or falling of my Bosch Platinum Plugs. If it’s just the ground electrode that is eroded, for causes they point to: Aggressive fuel and oil additives.
