Causes and solutions for damage to the one-way valve

1. Problems with the exhaust gas recirculation system:
The vehicle's waste gas recirculation system itself has quality problems, and too many impurities in the exhaust gas cause the one-way valve to be blocked or aged.
Solution: Go to a professional maintenance point such as a 4S shop to check the exhaust gas recirculation system pipeline, etc.
2. Incorrect maintenance method:
Failure to maintain according to the maintenance cycle causes the one-way valve to age and wear too quickly.
Solution: Strictly perform maintenance according to the maintenance cycle recommended in the vehicle maintenance manual.
3. Problems with oil quality:
When the owner adds oil to the car, if he uses oil with very low purity or uses a fuel treasure, there is a high probability that the exhaust valve will be damaged suddenly.
Solution: Replace the oil with better quality.
4. Aging of the one-way valve:
If the one-way valve works for too long, it will age and be damaged.
Solution: Just replace the one-way valve.
