Nissan TD42 GU GQ + BorgWarner EFR 6258 6758 Turbo Oil Drain Hose Kit

Oil Drain System for TD42 Diesel Running EFR 6258 / 6758 Turbo

The legendary Nissan TD42 diesel engine, used across GQ and GU Patrol platforms, is highly favored for turbo upgrades due to its reliability and torque potential.

When fitting a BorgWarner EFR 6258 or 6758—whether upgrading a TD42 GU factory-turbo model or converting a TD42 GQ N/A engine—a proper turbo oil drain system is essential for maintaining lubrication stability and preventing oil backup in the CHRA.

This Gryphontek turbo oil drain hose kit includes a CNC-machined EFR-pattern drain flange, diesel-rated NBR hose, steel fittings, a 1 mm non-asbestos gasket, and high-tensile mounting hardware.

Designed specifically for the heavy vibration, sustained thermal load, and thicker oil viscosity characteristic of TD42 engines, it provides a reliable, leak-free oil return pathway suited for EFR turbo installations.
