Where is the crankcase vent pipe of the Tiida located?
2 Answers
The crankcase vent pipe of the Tiida is located on the valve cover. The lower part of the cylinder block where the crankshaft is installed is called the crankcase, which is divided into the upper crankcase and the lower crankcase. The upper crankcase is cast integrally with the cylinder block, while the lower crankcase is used to store lubricating oil and seal the upper crankcase, hence it is also known as the oil pan. Below is an introduction to the functions of the crankcase: 1. The crankcase is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. 2. The crankcase is subjected to the combined effects of centrifugal force from rotating masses, periodic gas inertial forces, and reciprocating inertial forces, causing the crankshaft to bear bending and torsional loads. 3. It prevents the deterioration of engine oil. 4. It prevents leakage from the crankshaft oil seal and crankcase gasket.
I remember driving the Tiida for several years. The crankcase ventilation tube is located above the engine, usually near the valve cover. You need to open the engine hood and look for a thin black or gray tube connected to the intake pipe. It's a component of the PCV system, responsible for venting accumulated gases from the crankcase to prevent excessive oil pressure and contamination. If it gets clogged for a long time, it can cause oil leaks or engine vibration. When searching for it, don’t rush—feel around the central rear area of the engine bay, and follow the tube to locate the connection point. If unsure, you can refer to the owner’s manual or compare with images from online forums. My car had a similar issue, and I make it a habit to clean the dirt around the tube during annual maintenance to ensure smooth engine operation. It’s a small trick that saves money and hassle.
