Where is the PCV valve located on the Wuling Rongguang?

The PCV valve of the Wuling Rongguang is located inside the crankcase. Here are the specific details: 1. Function of the PCV valve: During the end of the engine's combustion process, some unburned mixture leaks into the crankcase under high pressure through the piston rings. These blow-by gases can escape into the atmosphere, causing pollution. If these gases are not removed, they can dilute the engine oil in the crankcase, leading to oil degradation and premature wear of engine components. Therefore, a PCV valve is installed on the valve cover to allow these exhaust gases to re-enter the engine through the intake manifold for re-combustion. 2. Working principle of the PCV valve: The PCV valve is controlled by vacuum. When the engine is idling, the intake manifold generates vacuum, which pulls the plunger against the spring force, preventing the exhaust gases from flowing. At high speeds, the spring force holds the plunger in place, also preventing gas flow. At medium speeds, the vacuum suction from the engine's intake manifold overcomes half of the spring force, causing the plunger to oscillate within the valve body and allowing the exhaust gases to flow into the intake manifold.
My Wuling Rongguang has been running for several years, and I often tinker with engine maintenance myself. The PCV valve is usually located under the hood near the valve cover. You'll need to open the hood to find it—it's typically connected to the tube of the crankcase ventilation system and might be a small round valve body. Don't worry, I've encountered clogging issues several times. When fuel consumption suddenly spikes or the idle becomes unstable, I check it. The position is fixed but prone to dust accumulation—just use a small brush for cleaning, and avoid pulling hard to prevent damage. Regular cleaning can prevent abnormal engine pressure, which might otherwise lead to emission issues or accelerated wear. If you get engine oil dirty while working, make sure to wipe it clean. The engine design of the Wuling Rongguang isn’t too complicated. Once you locate it, it’s best to check it during every maintenance session to ensure no carbon buildup accumulates—this way, your car will run smoothly and hassle-free.
