Keep your Nissan YD25DDTI turbo-diesel engine running clean and leak-free with this Gryphontek Turbo Oil Return Line Kit, engineered as a direct-fit replacement for the factory drain assembly used with the RHF4 VN4 turbocharger.

The factory return pipe and rubber hose often harden, crack, or leak after long exposure to heat and vibration—leading to oil seepage, smoke, and messy engine bays.

This upgraded kit uses a high-temperature silicone oil drain hose and a precision CNC-machined 6061-T6 aluminum flange to ensure a perfect seal and reliable oil return flow under heavy diesel operation.

Ideal for turbo rebuilds, upgrades, or preventative maintenance, it delivers OEM fitment with enhanced durability and temperature resistance.
