Nissan TD42 GU GQ + Garrett GT28R Turbo Oil Drain Hose Kit

Oil Drain System for TD42 Diesel Upgrading to Garrett GT28R

The Nissan TD42 diesel engine, used across GQ and GU Patrol platforms, responds extremely well to turbocharging thanks to its robust construction and torque-rich design.

When installing a Garrett GT28R—whether as an upgrade on a TD42 GU turbo engine or as part of a full TD42 GQ N/A turbo conversion—a correct oil drain system is essential to maintain proper CHRA lubrication and avoid oil pooling.

This Gryphontek turbo oil drain hose kit includes a GT-series CNC-machined drain flange, heat-resistant NBR oil drain hose, heavy-duty steel fittings, a 1 mm non-asbestos gasket, and high-tensile bolts.

Purpose-built for the vibration, thermal load, and diesel oil viscosity characteristic of TD42 engines, the kit provides a stable and leak-free oil return pathway for GT28R turbo setups.
