Where is the PCV valve located on the Wuling Hongguang?

The PCV valve of the Wuling Hongguang is located near the rear side of the throttle body in the engine compartment. Below are the relevant details: 1. Composition: The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled. Its main functions are: to direct gases from the crankcase into the intake manifold via the PCV valve, with a small amount of air entering the intake manifold directly from the air filter through the PCV valve. This prevents icing at the throttle, incomplete combustion, and worsening emissions. It also prevents exhaust gases from entering the atmosphere and prevents engine oil from deteriorating. 2. Principle: The PCV valve is a metering control valve installed between the crankcase ventilation system and the intake system. The PCV valve is controlled by vacuum and regulates the flow of oil vapor from the crankcase ventilation system into the intake system. The flow rate is higher when the engine is running at high speeds compared to low speeds. Additionally, when engine backfire occurs, the PCV valve should cut off ventilation to prevent crankcase explosion.
I'm a beginner just starting to learn about car maintenance, and while studying the Wuling Hongguang, I came to understand the location of the PCV valve. It is generally installed near the engine valve cover or intake manifold, specifically in a spot that can be directly seen after opening the hood. You need to follow the crankcase ventilation hose to find it, as it connects to a small valve device; the location is usually at the top of the engine for easy daily inspection. If the details are unclear, it might be due to differences in the model year; older Wuling Hongguang models have a more fixed location, while newer ones might be slightly hidden. Once you know the location, I can regularly clean the valve body to prevent clogging, avoiding engine shaking or abnormal fuel consumption. It's recommended to refer to the user manual or watch online video tutorials for accurate positioning.
As someone with years of car repair experience, I'm very familiar with the location of the Wuling Hongguang's PCV valve. It's typically fixed on the port of the valve cover and connected to the intake system via a hose. When you open the hood, the valve itself is made of plastic or metal, about the size of a thumb, and usually located on the front side of the engine. Pay attention to the surrounding pipe layout when locating it; if clogged, it can cause insufficient crankcase pressurization, leading to engine noise or oil leaks. I recommend first visually locating the starting point of the hose for troubleshooting. Replacing the valve is simple but requires matching the correct model.
