Does the Old Excelle's Engine Oil Leak Need Repair?
4 Answers
If the Old Excelle's engine is leaking oil, it is necessary to promptly take it to a 4S shop for inspection and repair. 1. Introduction: An engine (Engine) is a machine that can convert other forms of energy into mechanical energy. Engines can be used as power generation devices or refer to the entire machine including the power device (such as gasoline engines, aircraft engines). 2. Classification: Engines include internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. Among them, the valve drive mechanism adopts a hydraulic support ball rocker arm structure. Compared with the hydraulic tappet valve drive mechanism commonly used in current gasoline engines, this novel valve drive mechanism has the advantage of relatively small friction torque, thus requiring less driving force, which can effectively reduce engine power consumption and fuel consumption.
When I drove my 2008 Excelle last year, I also encountered oil pan leakage. I suggest you assess the situation. If the valve cover gasket is leaking severely and oil drips onto the exhaust pipe, it's dangerous and you need to replace the gasket immediately. If it's just slight oil seepage due to aging oil pan sealant, temporary repair may not be necessary, but you should check the oil level weekly by opening the hood. Remember to clean the oil sludge in the engine compartment – mechanics say the areas covered by sludge actually leak the most. Prolonged oil leakage can corrode rubber parts of wiring harnesses, making repairs more expensive. It's better to spend a few hundred yuan to replace the gasket sooner rather than later.
My old Buick Excelle with 130,000 km just had its oil leak fixed last month. The crankshaft rear oil seal was leaking so badly that the dashboard warning light came on, and it cost me 3,800 RMB to fix, which required lifting the engine. If you see oil stains on the subframe or oil spots in the parking space, first clean them and use an oil test strip on the leak point, then check the leakage rate after three days. The repair shop owner taught me this trick: if it leaks more than a coin-sized amount daily, it must be repaired immediately, or it could lead to cylinder scoring; if it's just the valve cover gasket seeping, you can monitor it, but top up the oil every two weeks. Rubber component aging is a common issue with this car.
The location of oil seepage is crucial! A clogged crankcase ventilation valve can cause high pressure and oil seepage, which can be fixed by replacing the valve body yourself for just 60 yuan. If the valve cover gasket is aging and leaking onto the ignition coils, it must be replaced to avoid cylinder misfire. I once experienced oil dripping onto the generator pulley, causing slippage and sudden air conditioning failure, which was very dangerous. Now, I always keep engine cleaner in my car; when I spot new oil stains, I spray and clean to identify the source. Be wary of repair shop quotes: charging over 800 yuan for replacing a valve cover gasket including labor is a rip-off, as genuine rubber parts cost just around a hundred yuan.
