Engine piston rings are designed to last a long time, but they can go bad over time due to various reasons. One of the primary causes of piston ring failure is wear and tear, which can result from prolonged use, high mileage, and exposure to high heat and pressure. Additionally, inadequate lubrication or insufficient oil pressure can cause piston rings to fail prematurely. Overheating can also cause piston ring damage, leading to scuffing and scoring on the cylinder walls. In some cases, manufacturing defects or improper installation can also contribute to piston ring failure. Regular maintenance and inspection of the engine can help identify potential problems with the piston rings and other engine components before they lead to major damage. If you notice any of the aforementioned symptoms, it's best to have a professional mechanic inspect your engine to determine the cause and recommend the appropriate repairs.
