Engine oil leaks represent one of the most common and potentially damaging issues faced by car owners.

“Oil leaks can come in all sorts of shapes and sizes,” Sanville explains, emphasizing the variability of the problem. Ignoring these leaks can have “dire consequences,” as even minor seepage can compromise engine performance and longevity. The key, according to Sanville, is proactive detection and addressing the issue promptly.
Initial Assessment: Is it Really Leaking?
Sanville’s method begins with confirming the presence of a leak. The first step involves a thorough visual inspection of the engine compartment. “Be careful not to burn yourself on the engine if it is hot,” he cautions. Look for any signs of wetness around the engine, paying close attention to areas where oil might accumulate. Checking for stains is also crucial, as is a scan for visible puddles of oil or other fluids.

Sanville recommends a simple yet effective technique: placing a cardboard box directly under the engine overnight. “This way we can easily see if we have a leak or not,” he states. The next morning, the cardboard will reveal any drips, providing a clear indication of a leak’s presence.
Advanced Detection Methods: Dye and Powder
Once a leak is confirmed, Sanville outlines two methods for pinpointing its exact source. The first involves adding a leak detection dye to the engine oil.After running the engine for a period, a UV light can be used to illuminate the dye, revealing the leak’s location.
Alternatively,Sanville suggests applying a specialized powder to areas suspected of leaking. After running the engine,the powder will highlight the source of the leak. “Don’t do this when it’s wet outside,” he advises, as moisture can
