Piston rings are essential friction components that are largely responsible for the condition of the entire engine. When the rings are excessively worn, you may notice increased oil consumption, a drop in engine power and smoking. In this article you will find more information about damaged piston rings in cars.
Piston rings in a car - what are they responsible for?
The job of the rings is to seal the space located between the combustion chamber and the crankcase. It is worth mentioning that these components are made with tremendous precision, which is why almost the smallest damage affects their operation as well as the overall performance of the engine. If you drive an older car and have noticed a problem with the piston rings, it may turn out that a repair is not cost-effective. This says a lot about how important these parts are.
Failure symptoms - piston rings
Since we are dealing with damaged piston rings, it is worth writing a few words about how to recognise an approaching failure and not overlook rings that are operating incorrectly. The most frequently occurring symptoms are:
- fluttering of the rings and their uneven operation,
- starting problems,
- a noticeable loss of power,
- increased engine oil consumption.
Importantly, symptoms of this kind can be encountered both in petrol and diesel engines that are heavily loaded, as well as in those that do not deal with heavy overloads on a daily basis. It is therefore correct to state that damage to the piston rings can occur in any car, regardless of how it is used.
A way to deal with seized piston rings
If you have noticed a significant drop in power in your car, it means you may be dealing with seized piston rings. Excessive sluggishness in repairing this type of fault leads to a serious engine failure and rapid wear of the cylinders. The solution to the problem does not have to be a costly visit to a mechanic at all. Start by purchasing a specialised engine flush. Its cost is small compared to what you will have to pay at a workshop. All it takes is for you to flush the engine with the preparation every once in a while to protect the piston rings and significantly extend the life of the entire drive unit.
A cracked piston ring - why does this happen?
The most common causes of piston ring cracks are:
- fluttering of the rings,
- an irregularity in the formation of the mixture,
- increasing power with a standard piston (chip tuning of the controller),
- axial wear due to contamination.
Worn piston rings - replacement
Replacing piston rings is a job for a mechanic. So if you ignored the first symptoms of the fault and did not use a flush, you must seek help from a professional. Sometimes replacing the rings involves overhauling the entire engine and immobilising the vehicle for at least a week. In the context of effectively resolving the problem with the rings, it is important to choose an experienced specialist who will give you the assurance of avoiding mistakes and additional costs. Remember, however, that expensive repairs can be avoided through proper prevention and regular engine maintenance.
Worn piston rings - do-it-yourself replacement
Of course, you can try to replace worn piston rings yourself, but be aware that you will need power tools and specialised instruments for this. It may therefore turn out that assembling the costly equipment will make the do-it-yourself repair no longer cost-effective. If, however, you have experience in this type of work and know what you are doing, give it a try.
