Where is the PCV valve located on Baojun?
2 Answers
Baojun PCV valve is installed on the engine valve cover with a pipe connected to the engine intake pipe. The PCV hose arrangement varies depending on the engine model. The following is an introduction to the PCV valve: 1. Function: It directs the gas in the crankcase into the intake manifold through the PCV valve, and a small amount of air enters the intake manifold directly from the air filter through the PCV valve, which avoids phenomena such as icing at the throttle, incomplete combustion, and worsening emissions. It prevents exhaust gases from entering the atmosphere and also prevents engine oil from deteriorating. 2. Composition: The PCV valve consists of a valve body, valve, valve cover, and spring, and cannot be disassembled.
I remember often helping people repair Baojun vehicles, where the PCV valve location is quite consistent. After opening the hood, there's a valve cover on top of the engine – the PCV valve is mounted on it, connected to a tube leading to the intake manifold. In popular models like the Baojun 510 or 730, it's usually positioned at the rear, near the oil filler cap or spark plug area. To locate it, clean the engine surface for better visibility, and ideally work on a cooled engine to avoid burns. The PCV valve plays a crucial role in venting crankcase gases and maintaining engine pressure balance; if clogged or faulty, the car may shake noticeably or consume more fuel. Regular checks or replacement every 20,000 kilometers can prevent major issues – be careful not to damage the tube during replacement. The design ensures reasonable accessibility, though take care not to confuse it with sensor components.
