Is It Normal for the Exhaust Pipe to Emit White Smoke?

[PeterLynn]

It is normal for the exhaust pipe to emit white smoke without any unusual odor. Only when there is an issue with the engine's operation will the exhaust produce a noticeable odor. If the car's exhaust pipe emits a large amount of white smoke, or even sometimes discharges water, the main cause is usually water entering the cylinders due to a breach between the cylinder and the water jacket, commonly referred to as water jacket and cylinder liner leakage. During the initial startup of a car parked in winter or the rainy season, white smoke is often visible. Once the engine temperature rises, the white smoke will disappear, and this condition does not require maintenance. However, if the exhaust pipe emits black smoke after the engine temperature rises, it indicates low cylinder pressure or a non-functioning cylinder, which should be inspected and addressed.
