What are the symptoms of a bent connecting rod in an engine?

[Judah]

An engine with a bent connecting rod will fail to form a combustible air-fuel mixture and experience difficulty starting. Here are the detailed symptoms: Failure to form a combustible air-fuel mixture: When driving on waterlogged roads, the engine may draw water into the cylinder. The water initially entering the cylinder quickly turns into steam due to the high temperature, preventing the formation of a combustible mixture in that cylinder. Difficulty starting: Abnormal fuel injection in the engine can cause the connecting rod to bend or break. This usually occurs when a fuel injector in one cylinder continuously sprays fuel. Symptoms often include difficulty starting, rough idling, black smoke from the exhaust, and reduced power.
