If the seal is compromised or the cap is missing, the engine cannot maintain the correct pressure. Erratic oil pressure readings on the dashboard gauge.
This can result in inefficient lubrication, oil leaks, or even the ingestion of air that disrupts the oil pump's steady flow, potentially causing significant damage over time. Clean oil reduces friction between moving parts, which translates to better fuel efficiency and smoother operation.
