How to Detect Engine Oil Leakage?
2 Answers
Observe from the valve cover. The following is an introduction to detecting leaks: Observation location: Visually inspect the machine inside the car for oil leakage. Observe from the valve cover, which is located at the top of the engine, to check for any turbid seepage. If there are stains, it indicates that your car is leaking oil. Causes of leakage: The causes of oil leakage include: aging machine parts; poor machine sealing. Leakage conditions: Engine oil leakage can appear as patches or dots. Patches indicate that the machine has aged and requires replacement of parts, while dots indicate that the machine is beginning to age and needs maintenance and care.
Detecting engine oil leaks is actually quite simple, and I often do it at home. Checking for oil stains on the ground after parking is a good method, especially by placing a piece of cardboard in the garage or where you usually park and looking for black oil spots the next day. If there are many stains, quickly check if the dipstick level has dropped. Open the hood and inspect the engine bay for oil traces, especially near the oil pan, where gasket aging can easily cause leaks. Don't ignore the smell—a strong oil odor is also a sign. Regular oil changes and maintaining seals can reduce risks; otherwise, prolonged leaks can lead to engine overheating and costly, dangerous repairs. Make it a habit to check once a month to catch issues early and avoid bigger troubles.
