Answer:

Cracks and carbon tracking are common faults with distributor caps in the ignition system of an internal combustion engine.

Cracks and carbon tracking are common faults with distributor caps which are part of the ignition system in an internal combustion engine. The distributor cap is responsible for distributing high voltage electrical current from the ignition coil to the spark plugs in the correct firing order. Cracks in the distributor cap can allow moisture and dirt to enter, leading to misfires and engine performance issues. Carbon tracking refers to the formation of carbon deposits on the inside surface of the cap, which can cause electrical arcing and misfires.
