Will the car stop burning oil after replacing the PCV valve?

[ManuelLee]

When the cause of a car burning oil is a faulty PCV valve, replacing the PCV valve will stop the car from burning oil. Here is a detailed introduction about cars burning oil: 1. Overview: 'Burning oil' refers to engine oil entering the combustion chamber of the engine and participating in combustion along with the air-fuel mixture. If a vehicle exhibits 'burning oil,' it can lead to rapid damage of the oxygen sensor, increased carbon deposits in the combustion chamber, unstable idling, lack of acceleration power, increased fuel consumption, and excessive exhaust emissions, among other adverse effects. 2. Precautions: Severe oil burning can result in insufficient engine lubrication, causing irreparable damage to the engine or even rendering it unusable, significantly increasing repair costs and potentially leading to safety hazards.
