Nissan TD42 GU GQ + Hitachi HT18 Turbo Oil Drain Hose Kit

Oil Drain System for TD42 Running the OEM Hitachi HT18 Turbo

The Nissan TD42 diesel engine delivers exceptional durability and torque, making it a strong performer whether in factory-turbo GU models or GQ vehicles undergoing a turbo conversion.

When replacing aging factory hardware on a TD42 GU or adding a turbo to a TD42 GQ N/A engine, a correct oil drain setup is essential to maintain stable CHRA lubrication and prevent oil leakage or smoking.

This Gryphontek turbo oil drain hose kit includes a CNC-machined HT18 drain flange, high-temperature NBR oil drain hose, steel fittings, a 1 mm non-asbestos gasket, and high-tensile bolts.

Engineered for the vibration, heat, and heavy diesel oil typical of TD42 engines, it provides a clean and dependable oil return path for Hitachi HT18 applications.
