Manufactured to OE specifications for fit, function and durability, this 125cm oil pipe is engineered to withstand the high temperatures, pressures and demanding operating conditions associated with air-cooled Porsche engines. It is an ideal replacement for ageing, corroded or leaking original oil lines, helping to maintain the integrity and performance of the lubrication system.
What This Product Does:
- Transfers engine oil from the external oil tank to the engine.
- Forms a critical part of the Porsche dry sump lubrication system.
- Maintains a constant supply of oil to vital engine components.
- Supports effective engine cooling through oil circulation.
- Helps ensure proper oil pressure and lubrication performance.
- Protects internal engine components from excessive wear.
Symptoms Of Wear Or Failure:
- Visible oil leaks beneath the vehicle.
- Oil seepage around pipe connections or fittings.
- Corrosion or rust on metal sections of the pipe.
- Cracked, perished or deteriorated hose sections.
- Low engine oil levels due to leakage.
- Oil pressure fluctuations or warning lights.
- Burning oil smells from leaking oil contacting hot components.
- Excessive oil contamination around the engine bay or underbody.
Why Replacement Matters:
- Oil pipes are subjected to continuous exposure to hot engine oil, road debris, vibration, moisture and temperature fluctuations. Over time, corrosion, internal deterioration and physical damage can compromise the pipe's ability to safely transport oil throughout the lubrication system.
- A leaking or restricted oil pipe can reduce oil pressure, cause oil starvation and increase engine operating temperatures, potentially leading to costly engine damage. Replacing a worn or ageing oil pipe helps maintain correct oil flow, protects critical engine components and ensures the lubrication system continues to operate efficiently. An OE Match replacement restores reliability, preserves engine performance and helps safeguard the longevity of your Porsche engine.

Fits:
- Porsche 911 1978-1989 3.3L Turbo (930)
Diagram Ref No 18
Constructed from high-quality corrosion-resistant metal tubing with precision-formed bends and OE-style threaded connections, the pipe is engineered to withstand high oil pressures, elevated temperatures and constant engine vibration. It provides a secure, leak-free connection within the dry-sump lubrication system, helping to preserve engine performance and reliability.
What This Product Does:
- Transfers engine oil between the external oil thermostat and the crankcase.
- Maintains efficient oil circulation throughout the lubrication system.
- Supports correct oil temperature regulation.
- Delivers a consistent supply of lubricating oil to the engine.
- Helps reduce engine wear by maintaining proper oil flow.
- Works with the external oil cooling system to optimise engine temperature.
- Provides secure, leak-free oil transfer under pressure.
- Forms an essential part of the engine's dry-sump lubrication system.
Symptoms Of Wear Or Failure:
- Visible engine oil leaks.
- Oil residue around the pipe or threaded connections.
- Low engine oil level.
- Oil pressure warning light illumination.
- Oil smell from the engine bay.
- Corrosion or physical damage to the pipe.
- Cracked or leaking pipe connections.
- Reduced oil circulation.
- Increased engine operating temperatures.
- Premature engine wear caused by lubrication loss.
Why Replacement Matters:
- Oil pipes operate under high pressure and are continuously exposed to hot engine oil, vibration, road debris and environmental corrosion. Over time, the pipe can become damaged through corrosion, impact or fatigue, while threaded connections and sealing surfaces may deteriorate, allowing oil to leak.
- A leaking or restricted oil pipe can reduce oil pressure and compromise the lubrication of critical engine components. Continued operation with insufficient oil flow can accelerate wear of bearings, camshafts and other internal engine parts, potentially leading to severe engine damage and costly repairs.
- Replacing a worn or damaged oil pipe restores reliable oil circulation and protects the integrity of the lubrication system. An OE Match replacement provides factory-style fitment, durable construction and dependable sealing performance, helping maintain the engine reliability, performance and longevity expected from your Porsche.

Engine Cooling Oil System & Pipes – Precision Cooling and Lubrication for Porsche Performance
The engine cooling oil system and pipes play a crucial role in your Porsche’s performance and reliability. These components deliver and regulate oil flow between the engine, oil cooler, and filter, maintaining stable oil temperature and pressure. By keeping the oil cool and circulating efficiently, they help prevent overheating, reduce friction, and ensure smooth engine operation — even under extreme driving conditions.
At Design911, we offer a complete range of genuine and manufacturer-quality engine cooling oil system parts and pipes for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each component is engineered for precision fitment, high heat resistance, and long-lasting durability, ensuring your Porsche performs exactly as its engineers intended.
What Do Engine Cooling Oil System & Pipes Do?
The oil cooling system and its connecting pipes work
together to control temperature and maintain lubrication efficiency throughout
the engine. Their main functions include:
- Transporting
oil between the engine, oil cooler, and filter housing.
- Dissipating
excess heat from the oil to prevent breakdown under pressure.
- Maintaining
stable oil pressure for consistent lubrication.
- Supporting overall engine temperature regulation alongside the coolant system.
These parts ensure your Porsche’s engine oil stays at the ideal temperature and viscosity, protecting vital internal components from wear and damage.
Why Do Oil System Pipes and Components Fail?
Even with regular maintenance, oil cooling system components
can wear out due to heat, pressure, and age. Common causes of failure include:
- Corrosion
or cracking of metal oil pipes from long-term exposure to heat and
oil.
- Rubber
hose degradation from high temperatures or oil contamination.
- Leaks
at connectors or fittings caused by vibration or poor sealing.
- Blocked
or restricted flow from sludge or carbon build-up.
- Mechanical damage from debris or impact under the vehicle.
Signs of failure can include visible oil leaks, oil pressure warnings, overheating, or the smell of burning oil.
Why Replace Faulty Oil System Parts and Pipes?
A failing oil pipe or cooler line can cause oil loss, overheating, and even catastrophic engine failure if left unchecked. Replacing worn or damaged components ensures your Porsche’s oil circulation and cooling remain efficient and leak-free.
Benefits of replacement include:
- Restored oil flow and cooling performance.
- Prevention of leaks, overheating, and engine damage.
- Improved reliability and efficiency under all conditions.
- Manufacturer-quality materials for long-term durability.
All parts in this range are built from high-grade metals, reinforced hoses, and corrosion-resistant fittings, designed to meet or exceed factory standards for performance and longevity.
