What is a breather hose called?

A breather pipe allows an internal combustion engine to vent crankcase pressure out of the engine. Despite the name, it is actually a vent pipe. By venting pressure out of the crankcase, an engine’s piston rings are allowed to seal tighter against the cylinder walls.

What is the purpose of a breather hose?

Your breather hose aids a car or truck to obtain the proper level of oxygen into the engine’s combustion chamber for effective fuel combustion. A vehicle’s breather hose lowers pressure buildup in the engine and recycles air through the air intake system.

How important is a breather hose?

Do you need a crankcase breather?

The crankcase ventilation system works to relieve any pressure from the engine’s crankcase attributed to blow by gases by rerouting the gases back into the engine’s intake manifold to be consumed by the engine. This is necessary, as excessive crankcase pressures can cause oil leaks to form if allowed to build too high.

Can crankcase pressure cause oil leaks?

Side effect #1: Crankcase pressure (“My engine leaks oil”) If the engine is producing blow-by gases faster than the PCV system can dispose of them, an increasing surplus becomes trapped in the crankcase, causing excess pressure and, inevitably, oil leaks.

What happens when engine breather is blocked?

If an engine’s breathing system should become blocked or restricted, the crankcase will pressurise causing any one or more of the following problems: The oil/air mix will force its way out through any other convenient exit e.g. oil seals, dip stick, filler cap, etc.
