Is a Breather Hose important?
The Air Intake Breather Hose creates a partial vacuum in the Crankcase and other connected areas, but its primary function is a bit more specific. Here's a breakdown of what it does:
Primary Function of the Air Intake Breather Hose
- Ventilate the crankcase: The Breather Hose provides a path for these gases to escape the crankcase.
- Maintain pressure balance: This Vacuum prevents Oil leaks, reduces the risk of Engine sludge buildup, and improves engine performance.
- Direct gases to the intake manifold: The Breather Hose typically routes the Crankcase gases back to the air intake manifold. This allows the gases to be burned in the combustion chamber, reducing Emissions, and improving Fuel Efficiency.
- Separate oil mist: This feature prevents excessive oil consumption and protects the intake system from contamination.
So, while the Breather Hose does contribute to creating a partial vacuum, its main purpose is to Ventilate the Crankcase and direct the resulting gases back to the Engine for proper combustion.
What happens if my Air Intake Hose is broken?
A cracked air intake breather hose can cause a variety of symptoms, here are some to watch for:
- Rough idle
- Loss of power
- Hissing or whistling
- Increased engine noise
