What is crankcase breather hose?
A crankcase ventilation system removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the intake manifold). Early engines released these gases to the atmosphere simply by them leaking through the crankcase seals.
Why is there a breather hose on the crankcase?
The breather hose on your engine’s crankcase breather tower is a very simple yet important contributor to the overall health and good running of your motor. Over time, oil vapor from the crankcase will saturate the hose material, and cause it to collapse and restrict proper crankcase ventilation.

What are the components of crankcase breather system?
The advanced crankcase breather system upgrade includes the following components: Breather pre-separator Crankcase pressure regulator valve Breather separator assembly Breather check valve Breather insulation blanket Breather system tubing Mounting brackets
What does a crankcase vent do?
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.
What is an engine crankcase breather element?
The crankcase breather filter element is part of the PCV or positive crankcase ventilation system. The crankcase filter captures oil and other bad elements and prevents them from going back into the engine. This item is commonly replaced whenever you do a tune-up on the car.
