Where is the PCV valve located on the Wuling Rongguang?

The PCV valve of the Wuling Rongguang is located on the engine's cylinder head cover. Relevant information about the PCV valve is as follows: Introduction: PCV is the abbreviation of Positive Crankcase Ventilation, which means the positive ventilation control system of the crankcase (or oil pan). The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled. Main function: It directs the gases from the crankcase into the intake manifold through the PCV valve, with a small amount of air entering the intake manifold directly from the air filter via the PCV valve. This prevents phenomena such as icing at the throttle, incomplete combustion, and worsening emissions. It prevents blow-by gases from entering the atmosphere and also prevents engine oil from deteriorating. At the end of the engine's combustion process, some unburned mixture leaks into the crankcase under high pressure, which is referred to as "blow-by" in the industry. These blow-by gases can escape into the atmosphere, causing pollution. If these blow-by gases are not removed, they can dilute the engine oil in the crankcase, leading to oil deterioration and premature wear of engine components.
I've been driving the Wuling Rongguang for many years. The PCV valve is usually located on top of the engine, specifically at the valve cover on the cylinder head. Sometimes it's hidden near the small tube connection of the intake manifold. Last time I checked it myself, I found that if it gets clogged, the car would idle roughly and emit black smoke, which is quite troublesome. Its function is to vent crankcase gases and prevent sludge buildup. Regular cleaning can extend engine life. On the Wuling Rongguang, the position varies slightly depending on the model, but you can spot it easily when you open the hood. It's recommended to check it every 10,000 kilometers. If you really can't find it, refer to the user manual or ask a mechanic at an auto repair shop for help—don't force it to avoid damaging other components.
