Technical Description

The total reliability solution to eliminate "Burning Oil" risks and cabin odors. The Citroën 1.6THP (EP6) engine operates in an extremely high-temperature environment that inevitably destroys factory plumbing. The rigid oil feed (OE #037956) fails at its O-ring and crimp points, while the rubber drain hose (OE #037979) hardens and seeps oil. This GryphonTek Signature Series Complete Kit is the professional upgrade—replacing failure-prone OEM hardware with motorsport-grade PTFE Braided Stainless Steel and High-Temp Silicone.

  • Double Leak Protection: Replaces both the high-pressure feed and the high-flow return circuit. Our flexible designs eliminate the "rotation leak" phenomenon at both factory crimps and rubber junctions.
  • Precision Pressure & Flow: Features a 1.8mm restricted banjo bolt for the turbo side to protect internal seals, paired with a billet aluminum high-flow return fitting for unrestricted drainage.
  • Industrial-Grade Thermal Defense: Includes a high-temp PTFE core and reinforced silicone protected by an Aluminum Foil Corrugated Sleeve to survive intense radiant heat.
  • Direct Citroën Fitment: A 100% plug-and-play refresh for C4, C5, DS3, DS4, and DS5 models. Designed to navigate the specific EP6 engine bay geometry perfectly.

Why Upgrade / Why Choose +

The 1.6THP "Prince" engine runs notoriously hot. This constant heat soak "cooks" the factory O-rings in the rigid feed line and turns the rubber drain hose into a hard, brittle tube. Once these components lose their elasticity, they begin to seep oil directly onto the turbo and exhaust manifold. This is the primary cause of the "burning oil" smell that ruins the refined cabin atmosphere of your DS or C-series Citroën.

The GryphonTek Complete Kit is the professional choice to stop the leak cycle. By converting the entire oiling loop to a Flexible PTFE and Silicone Architecture, you remove the stress points that cause factory hardware to fail. It ensures your turbo receives perfect, regulated oil pressure while draining back freely to the engine block. Fix it once, fix it right, and restore the mechanical integrity your Citroën deserves.
