How to Deal with Engine Oil Leakage?
2 Answers
Engine oil leakage can be addressed through the following methods: 1. Replace the valve cover gasket; 2. Remove the engine timing cover and reapply sealant; 3. Tighten or replace the oil drain plug of the oil pan; 4. Replace the oil drain plug gasket; 5. Install a new oil filter; 6. Replace the oil pan gasket and reapply sealant; 7. Replace the crankshaft oil seal. The hazards of engine oil leakage include loss of engine oil, wastage, and potential engine damage due to insufficient lubrication. Causes of engine oil leakage: 1. Poor quality, material, or craftsmanship of components, along with structural design flaws; 2. Excessive engine temperature leading to aging of oil seals and gaskets, reducing sealing effectiveness; 3. Thermal expansion and contraction affecting tightening screws, resulting in uneven torque, loosening, or stripping; 4. External impacts or collisions causing deformation of internal engine parts, leading to oil leakage.
When you find an engine oil leak, don't panic. Stop the car immediately and check the engine compartment and underside for oil stains to identify the leak location. If it's a minor leak, you can wipe it with a tissue, add some new oil as an emergency measure, and drive slowly to the nearest repair shop. Prolonged oil shortage can cause the engine to overheat and damage internal components, so never ignore the potential fire risk. I usually do a preliminary diagnosis myself to determine whether it's a worn oil pan gasket or a valve cover seal issue, as these are the most common causes and relatively inexpensive to fix. For prevention, I recommend regular oil changes during maintenance, checking gaskets and bolt tightness each time, and avoiding high-RPM acceleration while driving. Addressing the issue promptly can save you a lot of money, preventing a small leak from turning into a major repair.
