A burnt spark plug is usually very black and covered in soot. The electrode may be melted or deformed and the porcelain insulation can be cracked or missing. If the spark plug is too hot, it can cause pre-ignition which will damage the engine.
A burnt spark plug looks like a blackened, carbon-covered electrode. The metal core of the electrode may also be eroded.

How to Tell If a Spark Plug is Bad by Looking at It
If your engine is having trouble starting, or if it’s running rough, one possible cause is a bad spark plug. But how can you tell if a spark plug is bad just by looking at it?
Here are some tips:
1. Check the electrode. The electrode is the metal tip at the end of the spark plug.
Over time, this can become worn down or corroded. If you see any damage, it’s likely that the spark plug is bad.
2. Look for deposits.
Another sign that a spark plug may be going bad is deposits on the electrode or around the threads. These deposits can interfere with the electrical current and prevent proper sparking from happening.
3. Check the gap.
The gap between the electrode and ground contact needs to be just right for proper sparking to occur. If it’s too wide or too narrow, then the spark plug isn’t working correctly and should be replaced..
Spark plugs are an essential part of your engine, so it’s important to keep them in good condition!
