A breather seal in a car is a component designed to prevent leaks and maintain proper pressure in the engine. It is typically made of rubber or silicone material and is installed in various parts of the engine, including the valve cover or crankcase.

The primary function of a breather seal is to allow fresh air to enter the engine while preventing oil or fuel vapors from escaping. It acts as a one-way valve, allowing the gases to escape from the engine but not allowing any contaminants or germs to enter. By maintaining the right level of pressure inside the engine, the breather seal helps prevent oil leaks and reduces the risk of engine damage caused by excessive pressure buildup.
