Turbocharger Oil Pipe – A precision‑formed steel tube that delivers pressurised engine oil to the turbocharger bearing housing, ensuring proper lubrication and cooling. Manufactured from seamless steel tubing with a corrosion‑resistant coating, this pipe features accurately flared ends and a smooth internal bore that minimises flow restriction. Its precise bends are designed to match the WP12 engine’s compact layout, ensuring a direct, kink‑free fit. The pipe is engineered to withstand oil pressures up to 8 bar and temperatures up to 150°C, guaranteeing long‑term reliability. This oil pipe is a direct replacement for the original factory component, offering identical flow characteristics and durability. It is critical for maintaining turbocharger bearing health and preventing seizure. Regular inspection for chafing, cracks, or corrosion is recommended, and replacement is advised if any damage is detected.

Union body – A precision‑machined metal fitting that provides a secure, leak‑free connection between the turbocharger oil pipe and the turbocharger or engine block. Manufactured from high‑strength steel or brass with a corrosion‑resistant coating, the union body features a precisely ground sealing surface that mates with the ferrule or pipe end to create a reliable metal‑to‑metal seal. Its internal passage is sized to match the pipe’s inner diameter, ensuring unrestricted oil flow. The union body is designed to withstand high oil pressures and temperatures, and its robust construction resists vibration and thermal cycling. This union body is a direct replacement for the original factory component, offering identical fit and sealing performance. Replacement is recommended if the sealing surface is damaged or if signs of corrosion are evident.

Ferrule – A precision‑formed metal collar that compresses around the oil pipe when the nut is tightened, creating a gas‑ and oil‑tight seal between the pipe and the union body. Manufactured from high‑grade steel with a hardened surface, the ferrule features a tapered inner bore that grips the pipe firmly, preventing it from pulling out under pressure. Its outer cone matches the union body’s sealing angle, ensuring a positive metal‑to‑metal seal. The ferrule is designed to be used once; it deforms plastically during installation to achieve a permanent, leak‑free joint. This ferrule is a direct replacement for the original factory component, ensuring identical sealing characteristics. It is essential for maintaining the integrity of the oil pipe connection and should be replaced whenever the pipe is removed.

Nut – A high‑strength hexagon nut used to secure the ferrule and union body, clamping the oil pipe into a leak‑tight connection. Manufactured from alloy steel with a zinc‑plated finish and heat‑treated to grade 10.9, this nut provides consistent clamping force and is designed to resist loosening under high vibration. Its precise thread pitch and class fit ensure consistent torque retention. The nut is often used in conjunction with the ferrule and union body to achieve a secure, leak‑free assembly. This nut is a direct replacement for the original factory part, ensuring identical strength and fitment. Replacement is recommended if threads are damaged or if signs of corrosion are evident. Proper torque application is essential to avoid over‑tightening, which can deform the ferrule or strip the threads.

Gasket – A precision‑formed sealing component that provides a gas‑ and oil‑tight seal between the turbocharger oil pipe assembly and the engine block or turbocharger housing. Manufactured from high‑temperature composite material or multi‑layer steel (MLS) with a precisely embossed sealing bead, this gasket withstands oil pressures up to 8 bar and temperatures up to 150°C. Its design compensates for thermal expansion and minor surface imperfections, ensuring a reliable seal over the engine’s service life. The gasket is resistant to oil and coolant, ensuring long‑term durability. This gasket is a direct replacement for the original factory component and must be replaced whenever the pipe assembly is removed, as old gaskets can lose their sealing effectiveness due to compression set. Installation requires clean, flat surfaces and proper torque on the fasteners to ensure even compression.

Turbocharger oil pipe assembly – A complete, ready‑to‑fit unit that includes the pre‑bent oil pipe, pre‑installed ferrules, nuts, and union bodies, simplifying installation and reducing the risk of assembly errors. Manufactured with the same high‑quality materials and precision as individual components, this assembly is factory‑tested for leak‑tightness and flow performance. Its design ensures that all connections are correctly oriented and torqued, eliminating guesswork during installation. This assembly is a direct replacement for the original factory unit, offering identical fit and performance. It is ideal for quick, reliable repairs and is supplied with all necessary seals and hardware for a complete replacement. Regular inspection of the assembly for chafing or corrosion is recommended, and replacement is advised if any damage is detected.

Bolt – A high‑strength fastener used to secure the oil pipe bracket, clamp, or back‑up block to the engine block or other mounting points. Manufactured from alloy steel with a zinc‑plated finish and heat‑treated to grade 10.9, this bolt provides reliable clamping force under high vibration and thermal cycling. Its precise length and thread pitch are matched to the specific mounting holes, and it is supplied with a pre‑applied thread‑locking compound to prevent loosening. This bolt is critical for maintaining the integrity of the oil pipe mounting system, and it should be replaced if threads are damaged or if signs of corrosion are evident. It is a direct replacement for the original factory part, ensuring identical strength and fitment.

Back‑up Block – A rigid steel reinforcement plate that provides additional support to the oil pipe mounting bracket or connection point, preventing distortion and ensuring even load distribution. Manufactured from high‑strength steel with a corrosion‑resistant coating, this block is positioned under the bolt heads or at strategic points on the bracket. Its precise thickness and flatness compensate for minor surface irregularities, reducing stress on the pipe and fittings. This back‑up block is essential for maintaining sealing integrity, especially under high vibration, and it should be replaced if it shows signs of bending or wear. It is a direct replacement for the original factory component and is critical for preventing oil leaks and pipe fatigue.

Sleeve – A protective covering or insulating barrier that slides over the oil pipe to prevent chafing, reduce noise, and provide thermal insulation. Manufactured from flexible, oil‑resistant rubber or plastic material, this sleeve is cut to precise lengths and fits snugly over the pipe. Its design allows for easy installation and replacement, and it is resistant to fuel, oil, and engine heat. The sleeve helps to dampen vibrations and prevent metal‑to‑metal contact that could lead to pipe wear. This sleeve is a direct replacement for the original component and is recommended for replacement if it shows signs of hardening, cracking, or deformation.

Pipe Clamp Assembly – A robust, pre‑assembled clamping unit that securely fastens the oil pipe to the engine block or chassis, preventing chafing and vibration‑induced wear. Manufactured from high‑strength spring steel with a zinc‑plated or rubber‑cushioned design, this assembly provides a firm grip while allowing for thermal expansion. Its locking mechanism ensures consistent clamping force and easy installation. The clamp is resistant to oil, fuel, and corrosion, ensuring long‑term reliability. This clamp is essential for maintaining proper pipe routing and preventing damage to the oil lines. It is a direct replacement for the original factory clamp and should be replaced if the rubber cushion is hardened or if the clamp shows signs of corrosion.

Ferrule Face Straight Thread – A specialised threaded fitting that combines a straight thread with a ferrule sealing face, providing a reliable, leak‑free connection for the oil pipe. Manufactured from high‑strength steel with a corrosion‑resistant coating, this fitting features a precision‑ground ferrule face that seals against the pipe or union body when tightened. Its straight thread design ensures easy installation and consistent clamp load. This fitting is essential for maintaining the integrity of the oil pipe connection and is a direct replacement for the original factory component. Replacement is recommended if the sealing face is damaged or if signs of thread wear are evident.
