The excessive smoke may also come in more consistent waves as the engine runs for long periods. However, when you start seeing it last longer than usual or appear a different color, you know a faulty seal may be the cause. The bluish smoke, which is burned oil, signifies that the engine needs a new seal, even if it clears after several minutes of running the engine.ĭepending on the machines and equipment you use, smoke is often a common form of exhaust. If this happens, it means the residual oil is passing down through the damaged seal and into the combustion chamber. When you start the engine, you may also see blue-tinted smoke appear from the exhaust. Leftover oil will then settle at the top of the valve cover head.
