Does Water in the Exhaust Pipe Affect the Car?

[StDawson]

Yes, it does. Water in the exhaust pipe can lead to severe consequences such as water entering the engine. If water has only entered the exhaust pipe, it is important to drain the accumulated water as soon as possible to prevent impurities in the water from clogging the catalytic converter or damaging the oxygen sensor. To drain the water, simply accelerate the engine to expel the water through the exhaust. Here are some related details: 1. Water in the exhaust pipe may cause blockage, leading to poor exhaust flow and engine stalling. However, in such cases, the engine may not necessarily take in water—it is commonly referred to as being "choked out." There is no need to worry; once the water drains out, the engine can be restarted. 2. Since water is far less compressible than oil, if a certain amount of water enters the cylinders under high pressure, it can easily break the engine's connecting rods or even puncture the pistons. It can also mix with the engine oil, rapidly degrading its effectiveness and ultimately causing engine seizure. In such cases, the engine is usually rendered irreparable.
