Does Engine Oil Leakage Require Repair?
2 Answers
Engine oil leakage requires repair. The reasons for engine oil leakage are as follows: Improper Engine Assembly: Insufficient surface cleaning, damaged sealing gaskets, and displacement. Sealing Component Failure: Sealing components were not installed according to the specified procedures, resulting in improper installation, insufficient or excessive tightening of nuts and screws, leading to loosening or breakage of screws; bending deformation of component mating surfaces or damage due to external forces, preventing even pressure and complete fitting. Aging of Sealing Components: Prolonged use of the engine causes aging and failure of sealing components, resulting in engine oil leakage. Excessive Pressure Difference: A large pressure difference between the inside and outside of the engine causes oil to leak directly from weak sealing points.
Engine oil leakage can be a minor or major issue depending on the situation. If oil leaks near the exhaust pipe, it's highly prone to catching fire under high temperatures, almost like hiding a lighter in your car. My neighbor's old Toyota had an oil leak that was ignored, and it ended up smoking on the road, with towing costs higher than the repair bill. Nowadays, there's a fluorescent leak detector on the market that's quite practical—just pour it into the engine oil and use a UV light to locate the leak, making it easy for DIY preliminary checks. However, don't delay fixing leaks caused by aging seals. Accumulated sludge can clog oil passages, leading to more than just a gasket replacement—it might require an engine overhaul. For older cars, check the dipstick level frequently, and don't drive if it's below the minimum mark.
