Oil pan/plug wetness — leak source diagnosis

Tags: #oil-leak · #drain-plug · #oil-filter

Wetness around the oil cartridge/filter area suggests a possible oil leak. Diagnosis method: wash all surfaces with brake cleaner, then re-inspect after another ~5,000 km to identify the actual leak source¹²³. Suspected sources: the oil drain plug, the filter, or the cartridge seal⁴⁵. Solution: replace the plug/seal if it's genuinely leaking — note that this is not critical unless it's a major leak, and many engines "sweat" a small amount of oil externally without it being a real problem⁶⁷⁸⁹.
