## 🔌 Function

Carries crankcase gas or separated oil between the breather connections, holding the bore and routing so the crankcase can vent freely.

## ⚠️ Common Signs of Failure

-   Oil misting from a split, or an oily film along the breather run
-   Crankcase pressure showing as oil pushed past a seal or the filler cap lifting
-   Hose found hard and cracked, or soft and swollen
-   Hose collapsed inwards so it closes under suction
-   Chafe mark or rub-through where the hose passes a bracket

## 🛠️ Service Notes

-   Three breather hoses sit close together in this group - 20799616 at 0.014 kg, 20799065 at 0.016 kg and 20799617 at 0.027 kg - so order by drawing position rather than by weight
-   Check the separator and its return line are clear if the hose has been filling with oil
