A rocker arm can break due to several factors, including excessive wear from prolonged use, material fatigue from repeated stress cycles, or improper installation leading to misalignment. Additionally, insufficient lubrication can cause overheating and failure. In some cases, a sudden engine malfunction or a foreign object entering the engine can also result in a catastrophic break. Regular maintenance and inspection can help prevent such failures.

Spark Plug Wear and DamageNo, a bad distributor cap will not damage new spark plugs.What does cause damage to spark plugs includes:"Cross-threading" when attempting to screw the plugs into the engine head (s). This will not only ruin the threads on the plug, BUT worse... ruin the threads in the engine head (s).Improperly handling of the plugs [dropping to floor which can break or bend the ground terminal, or break the ceramic part of the plug].Improperly set gap [can cause bad ignition resulting in burning or carbonizing on the plug].There may be some other causes for damage to spark plugs that I cannot think of at this time.
