Is Oil Leakage from the Oil Filler Port a Common Phenomenon?

[VanArthur]

Oil leakage from the oil filler port is a common phenomenon. Below is some extended information related to oil leakage from the oil filler port: 1. Minor leakage: If the leakage is minor or consists of oil vapor, it will not have a significant impact on the engine. You can continue to use the vehicle while monitoring the situation. The leakage usually occurs at the seams, and sometimes simply tightening the relevant screws can resolve the issue. 2. Persistent leakage: If the leakage persists over time, it is advisable to have it inspected and repaired at a professional repair shop. Although this leakage may not affect the overall operation of the engine, it will deplete the oil in the lubrication system (as it is definitely engine oil that is leaking). Over time, this will reduce the effectiveness of the lubrication system and ultimately impact the engine's lifespan.
