Should a Bent Engine Connecting Rod Be Replaced?

[OLuke]

For safety reasons, it is advisable to replace a bent engine connecting rod. Consequences of a bent connecting rod: When the water level exceeds the engine's air intake during water wading, water can be sucked into the engine cylinders. Since water is incompressible, the immense reverse force can cause the connecting rod to bend and rub against the engine cylinder block. In severe cases, this can lead to a bent connecting rod, a broken crankshaft, or even damage to the cylinder block. Effects after repairing the connecting rod: After repairing a bent engine connecting rod, it generally does not affect normal use. However, even with careful reassembly, the engine may not meet the original manufacturer's standards. This is because it's impossible to guarantee that the new parts will have identical parameters to the original components in all aspects. There might be slight impacts on power and noise levels. Additionally, the newly replaced parts require a break-in period with the vehicle. During this time, avoid heavy acceleration or overloading the engine, and refrain from aggressive driving in daily use.

I've driven trucks for over a decade and encountered many engine issues. A bent connecting rod is the worst-case scenario that absolutely requires replacement. Last time my vehicle shook violently, the mechanic found a bent connecting rod and warned me that if not replaced, internal engine friction would drastically increase, accelerating wear on pistons and cylinder walls. In severe cases, even the crankshaft could be damaged, leading to complete engine failure. Bent connecting rods can't be repaired because the hardened material loses significant strength when straightened, making them prone to fracture and potential accidents during operation. Spending a few hundred dollars on a new connecting rod is a small investment compared to paying tens of thousands for major repairs later. Remember this lesson – driving safety comes first.
