This hard return line ensures proper gravity‑assisted oil drainage from the turbocharger bearings back to the sump, preventing oil pooling in the turbos which can lead to smoking, seal wear, or bearing damage. As a direct OEM‑fit component, it matches factory routing, fittings, and pressure/temperature tolerances, making it essential when servicing or replacing the oiling system on Z32 twin‑turbo engines.
