What are the symptoms of a faulty Honda VTEC valve?

[Abigail]

When the Honda VTEC is damaged, the symptoms of the car include a faulty exhaust valve. A damaged exhaust valve can cause oil vapor to enter the intake pipe and then enter the cylinder for combustion, which is commonly referred to as "oil burning". Additional information about valve issues is as follows: 1. Whistling sound: If you hear a whistling sound, it can generally be confirmed as an issue with the exhaust valve. 2. Symptom variations: The symptoms of a damaged exhaust valve can vary depending on the brand. Since the actual vehicle cannot be inspected, an accurate judgment cannot be made. 3. How to repair: In practice, you can go to a 4S shop or a professional auto repair shop to seek help from professionals. The exhaust valve is commonly referred to by its colloquial name; its technical term is the pressure control valve or oil separator. The exhaust valve is installed between the compressor outlet and the condenser inlet, improving heat transfer efficiency in the condenser and evaporator through separation.
