The internal combustion engine contains a component called a connecting rod. It is responsible for connecting the piston and the crankshaft together. Not only that, the connecting rod assists the piston in its downward and upward movements. Basically, the turning motion of the crankshaft causes the connecting rod to turn as well. Once the connecting rod turns, it allows the piston to move up and down. This is how rotational torque gets created in the engine.

The Top 4 Symptoms

A connecting rod needs to be strong and durable for the engine to survive. If it is too weak to handle the load of the combustion, then all the pressure will wear it down and bend it out of shape. This would be a very bad thing for the engine because there would be no more intake strokes, exhaust strokes, compression strokes, or power strokes.

As for the driver, they will be able to notice when this occurs because there will be some very noticeable symptoms present. Below are the top 4 symptoms of connecting rod failure that could happen to you.

Low Engine Oil – If you have a bad or failing connecting rod, then it may cause your engine to consume too much oil. Because of this, you may find that your engine always has a low level of oil. Either that or your existing oil will need to be changed more often than usual.

Engine Knocking Sounds – When your engine is turned on and running, you may hear a knocking sound coming from it. This will be a repeated knocking sound that gets faster as your engine speed increases. The sounds may go away after a short while, once your oil has a chance to circulate through the engine components and lubricate them.

Reduced Oil Pressure – A bad connecting rod could have devastating effects on your engine’s oil pressure. There may be an oil pressure gauge on your engine which will tell you when it has low oil pressure. You could have a warning light on your dashboard that will tell you as well.  If you have low oil pressure, then it means oil cannot circulate properly through the engine. This might lead to an overheated engine if the problem is not resolved quickly.

Bent or Damaged Rod – If you suspect that you have a bent or damaged connecting rod, based on the other symptoms which may be present, then you need to visually inspect the rod yourself to see what its condition is. This would require your engine to be disassembled, which is a job that only a mechanic should do.
