What are the symptoms of a bent engine connecting rod?

[DiSpencer]

If the engine connecting rod is slightly bent or deformed, it may result in the engine failing to start. After starting, the engine may exhibit unstable idling, severe shaking, and accompanied by knocking sounds. Additionally, professional tools are required for measurement, which needs to be conducted at a repair shop. Extended Information: The following are the causes of a bent engine connecting rod in a car: 1. Water entering the engine cylinder: As the amount of water increases, it accumulates on top of the piston, reducing the effective volume of the combustion chamber, increasing compression resistance, and consequently increasing the pressure transmitted from the piston to the connecting rod. 2. Abnormal engine fuel injection system: This situation is usually caused by continuous fuel injection from one of the engine's injectors. Symptoms often include difficulty starting, unstable idling, black smoke from the exhaust pipe, and reduced power. 3. Connecting rod seizing with the crankshaft: This is generally caused by poor engine lubrication and can be determined by checking the wear condition of internal engine components. 4. Issues with the connecting rod itself: This can usually be confirmed through methods such as chemical composition analysis of the connecting rod material, hardness testing, metallographic examination, and scanning electron microscope fracture analysis.

If the engine connecting rod is bent, you'll definitely notice something wrong while driving. I've encountered similar cases when I used to repair cars frequently. The key signal is abnormal knocking noises, especially a thumping sound during acceleration or uphill driving, like metal hitting metal. Engine vibration also increases significantly, with the steering wheel or the entire car body shaking violently. In terms of performance, you'll feel a lack of acceleration power—no matter how hard you press the gas pedal, it feels like a snail crawling, with a noticeable drop in power output. Sometimes it's even difficult to start the engine, or it suddenly stalls while running, all because the bent connecting rod affects piston movement. If you see blue smoke or an abnormal increase in engine oil level, it's even more dangerous, as the cylinder wall might be damaged. I recommend stopping immediately for inspection—don't push through and keep driving, or the engine might be ruined. Regular maintenance and oil changes can prevent this issue, as can avoiding water ingress or overloading accidents that cause bending.

My car had the same issue last year. While driving, there was suddenly a loud 'clunk' sound from the engine area, like someone hitting a metal barrel. The steering wheel started shaking violently, and even when I pressed the accelerator, the car struggled to climb hills. Later, it took several attempts to start the engine, and sometimes it would stall unexpectedly at red lights. The mechanic explained it was due to a bent connecting rod, which made me realize the danger: there was excessive oil leakage leaving stains under the car, along with faint blue smoke. Thinking back now, it's scary – continuing to drive could have worsened the vibrations and caused more severe engine damage. If you notice unusual noises or shaking while driving, pull over immediately and seek help. For a quick check, you can feel the hood for abnormal vibrations. Don't wait until it breaks down to fix it – addressing issues early saves both money and hassle.

A bent connecting rod is really frustrating! When you drive, the engine sounds like a drum beating, especially when you step on the gas to accelerate. The engine vibration becomes super obvious, and the whole car shakes. Power drops instantly, and the car struggles to climb hills like it hasn't eaten. Starting the engine might be difficult or fail, and it's prone to stalling while running. When I was into car modifications, I experienced this: a slight bend might let you drive, but you should replace it to avoid further damage. Prevention means keeping water out of the engine, like avoiding deep puddles. Regularly check the oil to reduce wear. Safety first—if the noise gets loud, stop driving and don't take risks.

A bent connecting rod poses serious risks. In my experience handling such issues, I've observed critical warning signs: the engine produces repetitive knocking noises that intensify with acceleration. Vehicle vibration increases significantly, sometimes affecting steering control. Sudden drops in power output and sluggish acceleration can create dangerous situations. Difficulty starting the engine or unstable operation are also common indicators. If left unaddressed, oil leaks or blue smoke may lead to fire hazards. I strongly recommend pulling over immediately for inspection if these symptoms appear while driving - never delay repairs. For prevention, avoid overloading your vehicle and never start the engine in flooded conditions.
