Risk of contamination: The breather tube may allow dirt, debris, and moisture from the atmosphere to enter the oil tank. This can contaminate the oil and potentially cause damage to the engine components.
Pressure buildup: If the vent on the oil tank is not properly sized or becomes blocked, it can cause excessive pressure to build up in the crankcase. This can lead to leaks, gasket failures, and other problems.
Environmental concerns: Releasing engine gases directly into the atmosphere without any form of filtration or control can contribute to air pollution and may not comply with local environmental regulations.
Instead of routing the breather tube directly into the oil tank, it is generally recommended to use an air-oil separator or catch can. These devices help to remove moisture, dirt, and other contaminants from the crankcase gases before they are released into the atmosphere. This helps to protect the engine and ensures that harmful emissions are minimized.
You should consult with a qualified mechanic or refer to the specific guidelines provided by the vehicle manufacturer for proper breather tube routing and any additional precautions or modifications needed for your specific vehicle.
