## 🔌 Function

Provides an accessible path for draining engine oil during servicing.

## ⚠️ Common Signs of Failure

-   Oil leakage at the nipple or cap
-   Cracked or hardened hose
-   Chafing against the engine
-   Damaged drain fitting
-   Hose left unsecured below the oil level

## 🛠️ Service Notes

-   Route the hose to a drain point that stays accessible with the engine installed, since its whole purpose is to let an oil change be done without disturbing the sump plug
-   Refit it using the original nipple, washers and support brackets rather than improvising a clamp-only fixing, and keep the run clear of hot exhaust or turbo surfaces
-   Check the hose for hardening or cracking at each oil change, since it carries hot oil for as long as it is fitted, not just during the few minutes of a drain
