Where is the crankcase ventilation valve of Tiggo 3 located?

The crankcase ventilation valve of Tiggo 3 is located on the valve cover. Depending on different engine operating conditions, the crankcase ventilation valve automatically controls the recirculation amount of blow-by gas by utilizing the changes in intake manifold vacuum. If the crankcase ventilation check valve is damaged, it will cause increased pressure inside the crankcase, excessive oil consumption, and also affect the exhaust emissions. The Tiggo 3's headlight assembly is equipped with lenses, and LED daytime running lights are installed in the fog light area. In terms of configuration, the Tiggo 3 is equipped with a three-spoke multifunction steering wheel adjustable for height, electrically adjustable exterior rearview mirrors, a rear wiper, a trip computer display, reverse parking sensors, a rearview camera, a GPS navigation system, driver and front passenger airbags, seat belt reminder, central locking system, child safety locks, and remote control key.
When tinkering with my Tiggo 3 engine, I often observe the PCV (Positive Crankcase Ventilation) valve location. It's typically positioned on the valve cover at the top of the engine - that metal-capped area with a thin tube connecting to the air intake manifold system. To be specific, after popping the hood, look up at the right-side engine section and you'll spot it resembling a mushroom-shaped valve embedded there. Its function is to vent internal engine gases, preventing oil sludge buildup that could impair performance. Regular inspection is crucial - blockage may cause sluggish acceleration or smoke emission. During each maintenance, I use compressed air to blow out dust from the valve port, ensuring unobstructed ventilation.
