Maintain consistent oil delivery and clean turbo drainage on your Nissan Cabstar F24M / F24W YD25DDTI with this Gryphontek Turbo Oil Feed & Return Line Kit, engineered as a comprehensive OEM-style replacement for the RHF4 VN4 turbocharger.

Cabstar commercial engines often operate for long hours under load, making the factory steel feed line and rubber drain hose especially prone to heat damage, internal restriction, and oil leakage.
This upgraded kit replaces both critical turbo lubrication pathways:

  • The 4AN PTFE Teflon stainless-braided oil feed line delivers stable, filtered oil pressure to the turbo.

  • The high-temp silicone return hose ensures unrestricted oil flow back to the sump, preventing drain-side pooling or leaks.

Ideal for fleet maintenance, turbo replacements, or preventive servicing, this kit offers clean routing, improved durability, and a direct bolt-on fit for Cabstar-specific engine layout.
