Is Replacing Engine Connecting Rods Considered a Major Overhaul?

[ArthurMarie]

Replacing engine connecting rods is considered a major overhaul. Below is expanded content about connecting rods: Reasons for connecting rod breakage: Water entering the cylinders can increasingly compress and pressure the connecting rods, leading to bending or deformation upon removal. Abnormal fuel injector operation, such as continuous fuel injection in one cylinder, significantly increases the likelihood of connecting rod bending or deformation. Additionally, observe if the engine exhibits difficulties starting, emits black smoke, or lacks power. Methods to prevent connecting rod breakage: If it's not yet time for the scheduled oil change, regularly check the oil level to ensure it's sufficient. Promptly top up the oil if the level drops or is insufficient to prevent engine wear due to oil starvation. When it's time for the scheduled oil change, typically every 500 hours, always use original manufacturer oil or oil of the same brand and specification as the original.
