Is Minor Engine Oil Leakage a Problem?
2 Answers
Minor engine oil leakage is not a serious issue. It is recommended to continue using the vehicle while monitoring the situation. For seepage or minor leaks, simply identify the location, which is often at joints. Sometimes, tightening the relevant screws yourself can resolve the issue. An engine is a machine that converts other forms of energy into mechanical energy. It can refer to either the power-generating device or the entire machine including the power unit. Engine maintenance methods include: 1. Regularly change the engine oil and oil filter; 2. Maintain good crankcase ventilation; 3. Periodically clean the fuel system; 4. Regularly clean the radiator; 5. Periodically clean the crankcase.
Honestly, minor engine oil seepage is quite common, but it depends on the location and severity. From my experience, valve cover gasket aging is the most frequent cause of seepage. It usually doesn't affect driving temporarily, just looks annoying, and over time oil vapor can stick to the intake pipe. If oil drips onto the exhaust pipe, the engine compartment might even smoke, which can be really alarming. The most concerning is leakage from the crankshaft front/rear oil seals - dripping onto hot components could potentially cause a fire at any moment. I've seen people place paper towels at the seepage spot and drive for a couple days to observe oil stain spread before deciding whether to repair. For older cars, some oil seepage from aging rubber parts is inevitable - the key is to regularly check oil levels by opening the hood, don't wait until it all leaks out and causes cylinder scoring.
