piston ring damage what you need to know

The primary task of the piston rings, located inside the engine of your car, is to seal the combustion chamber, regulate the engine’s oil consumption, and transfer heat from the piston to the car engine.

Based on these three tasks, it is easy to see why piston rings are so important in managing the seamless running of your car. As with all running parts of any mechanical device, the piston rings can experience wear and tear.

For this reason, it is important to look out for signs or symptoms of damage to the pistons as quickly as possible to prevent damage to the car engine.

4 Signs of Damage to the Piston Rings

Since the piston rings are a key component in the functioning of the car engine, any kind of damage to the piston rings will have an impact on the performance of your car. Here are 4 signs that all is not well with the piston rings:

  1. Excess Exhaust Smoke

One of the first signs of piston ring damage is when the car starts producing excess exhaust smoke. Here’s what you should know:

  1. Excessive Oil Consumption

Since one of the tasks of the piston rings is to regulate oil consumption of the engine, if there is any damage to the piston rings the oil will leak into the combustion chamber of the car engine.

  1. Drop in Acceleration Power

If you notice that the engine is not responding to the gas pedal in the way that it should, then it is time to consult with a professional mechanic. Keep the following in mind:


  1. Drop in Overall Performance

When the car engine loses its power, it can become completely unresponsive to acceleration, leading to an overall drop in the performance of the car.

NOTE It’s important to note, while the cost of a piston ring set is not high, retailing somewhere in the range of $30-$150, the bigger for repair is directed towards labor since the engine will have to be entirely removed to access the piston rings.

Once the piston rings are replaced, the engine will have to be reassembled and placed inside the car again. This can easily take up to 10 hours.

Thinking Ahead

Preventive maintenance of course is crucial to keeping your car in decent condition and running smooth. However, knowing what to watch out for by way of wear and tear of the various parts of your car can help you prevent serious car repair issues before they happen or before it is too late.

Since failing or damaged piston rings can impact engine performance, it is best to have them replaced as soon as possible for the simple reason that engine repair costs are among the highest when it comes to car repairs.
