What to do if the valve cover of the Tiida is leaking oil?

To fix a leaking valve cover on a Tiida, simply replace the valve cover gasket. The function of the car valve is to specifically input air into the engine and expel exhaust gases after combustion. In terms of engine structure, it is divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion; the exhaust valve's role is to expel the burned exhaust gases and dissipate heat. Symptoms of damaged car valves are as follows: 1. It will affect the engine's efficiency, reducing the car's power; 2. It will produce abnormal noises, the engine may experience unstable idling or poor acceleration during operation, overtaking performance may also decrease, in severe cases, it may cause difficulty starting the engine, leading to failure to ignite, and the car may also experience air leakage or increased carbon deposits; 3. Damaged valves can cause unstable cylinder operation, leading to engine shaking, lack of engine power, and may also lead to blockage of the exhaust pipe, in severe cases, it may cause the exhaust to emit black smoke.
My Tiida also had the issue of valve cover oil leakage. At first, I thought it was a minor problem, but then I noticed oil stains all around the engine. The cause is usually due to aging or loosening of the valve cover gasket, which is a common issue with Tiida models. I immediately went to the repair shop for an inspection, and they recommended replacing the gasket directly. You can also try DIY solutions, such as tightening the bolts first to see if it stops the leak, but replacing the gasket is more reliable. When replacing it, make sure to clean the valve cover surface to avoid old oil residue causing sealing failure. The cost is not high, around 500 RMB for materials and labor. Don’t delay—oil leakage can drip onto the exhaust pipe, potentially causing a fire if the engine overheats, and it also increases environmental pollution and oil consumption. Fixing it promptly saves money and hassle. After the repair, remember to check the engine every six months and keep it clean.
