Nissan TD42 GU GQ + Garrett G-Series G25 Turbo Oil Drain Hose Kit

Oil Drain System for TD42 Diesel Running Garrett G25-550 / G25-660

The Nissan TD42 diesel engine—famed for its strength, reliability, and massive low-end torque—is a top choice for turbocharging.

When upgrading to a Garrett G-Series G25-550 or G25-660, whether on a TD42 GU factory turbo model or a TD42 GQ N/A engine, a properly engineered turbo oil drain system is essential to ensure stable lubrication and prevent oil pooling in the CHRA.

This Gryphontek turbo oil drain hose kit provides the correct G-Series CNC-machined drain flange, high-temperature NBR oil drain hose, steel fittings, a 1 mm non-asbestos gasket, and high-tensile mounting hardware.

Built to handle the heavy vibration, constant thermal load, and high-viscosity diesel oil typical of TD42 engines, it delivers a dependable, leak-free oil return path for G25-series turbo setups.
