Where is the crankshaft ventilation valve located on the Verna?

The crankshaft position sensor on the Verna is installed on the engine's crankshaft. Its working principle is to provide signals for ignition timing (ignition advance angle) and confirm the crankshaft position, which are used to detect the piston top dead center, crankshaft angle, and engine speed. The function of the crankshaft position sensor is to determine the position of the crankshaft, specifically the crankshaft angle and engine speed. The Verna's body dimensions are 4300mm in length, 1705mm in width, and 1460mm in height, with a wheelbase of 2570mm. The car is positioned as a compact vehicle. In terms of power, it is equipped with a 1.4L L4 naturally aspirated engine, delivering a maximum horsepower of 95 and a maximum torque of 132.4 Nm.

To locate the PCV (Positive Crankcase Ventilation) valve on a Verna, it's typically positioned in the engine bay near the top of the engine. It connects to the end of a small tube adjacent to the valve cover or intake manifold. Having driven my Verna for several years, I once experienced unstable idling and blue smoke from the exhaust pipe—turns out it was due to a clogged PCV valve preventing oil vapors from escaping. To find it, remove the engine cover and trace the rubber tube extending from the crankcase; you'll spot a small plastic component, which is the PCV valve. While not entirely hidden, its position isn't obvious either, requiring some patience to locate. It's advisable to perform this check when the engine is cold to avoid burns. The Verna's layout resembles most modern vehicles, making manual inspection relatively straightforward. Regular cleaning helps prevent carbon buildup and excessive oil consumption, averting major engine issues. If unsure, recording a video or consulting a professional shop is safer, as DIY work warrants caution around electrical connectors.

Last time I fixed the crankshaft ventilation valve issue on my Verna, the location was actually not hard to find. Just open the hood and look towards the top of the engine - it's that small black plastic valve, usually mounted near the valve cover or by the intake pipe. At first I thought it was deeply hidden, but turns out a screwdriver was all I needed; it's connected to a hose leading to the crankcase to release excess gases and prevent pressure buildup. Remember when the valve got clogged that time, causing idle vibration? Cleaning off the oil residue fixed it. The placement is quite standard on the Verna. Just remember to disconnect the battery before working to avoid short-circuit risks. The maintenance manual doesn't explicitly show its location, but a quick online image search makes it clear - a ten-minute check at most. Don't wait for the warning light; just glance at the hose connections during car washes to avoid costly major repairs later.

The crankshaft ventilation valve of the Verna is installed on the cylinder head or valve cover in the engine compartment. Look for the connecting pipe, as the valve body is a small round-shaped plastic component. Its location is not overly complex, but be careful not to confuse it with other sensors. The valve is prone to carbon buildup and clogging, which can affect oil performance and exhaust emissions. During inspection, manually check the connection points—if there's looseness or oil contamination, replacement is necessary. Simple maintenance can extend the engine's lifespan.
