Previous Porsche Part Numbers: 91110773010 / 91110773011
The oil pipe carries engine oil between the oil tank and the thermostat as part of the Porsche 911 dry-sump oil system. The thermostat controls oil flow to the external oil cooler circuit when the oil reaches operating temperature, helping regulate engine oil temperature and protect the engine during driving.
Functions
• Replaces the oil pipe from oil tank to thermostat
• Supports correct engine oil circulation
• Forms part of the external oil cooling system
• Helps maintain stable engine oil temperature
• Supports dry-sump oil system operation
• Replaces corroded, leaking, crushed, blocked, or damaged original oil pipes
• OE Match replacement for Porsche 911 oil system repair and restoration.
Why Replace This Part?
External oil pipes are exposed to road dirt, heat, vibration, corrosion, oil pressure, and age-related wear. Over time, the pipe can corrode, leak, become crushed, seize at the fittings, or suffer damage during removal or repair work. A faulty oil pipe may cause oil leaks, reduced oil flow, poor cooling performance, or oil system reliability issues. Replacing the pipe helps restore secure oil transfer and dependable engine cooling.
When to Replace This Part
• Oil leaks are visible around the pipe or fittings
• The pipe is corroded, crushed, kinked, blocked, or damaged
• Oil thermostat or oil tank connections are being serviced
• External oil lines are being refreshed during restoration
• Fittings are seized or damaged during removal
• Engine oil cooling performance is reduced
• The vehicle is undergoing Porsche 911 oil system restoration
Where it fits on the car
This oil pipe fits between the oil tank and oil thermostat on Porsche 911 models. It forms part of the external engine oil circulation and cooling system.

The OE Match Oil Pipe Thermostat to Crankcase is a high-quality replacement engine lubrication component designed to carry engine oil between the external oil thermostat and the engine crankcase. Manufactured to OE specifications for fit, flow capacity and durability, this oil pipe plays a critical role in maintaining efficient oil circulation and ensuring the engine receives a consistent supply of lubricating oil under all operating conditions.
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 Oil Pipes & Hoses – Reliable Lubrication Flow for Porsche Performance
The engine oil pipes and hoses in your Porsche are essential components of the lubrication system, responsible for transporting oil between the engine, oil cooler, and various internal components. These lines maintain the correct oil pressure and flow, ensuring smooth operation, reduced friction, and long-term protection of your high-performance engine.
At Design911, we supply a wide range of oil pipes and hoses developed to meet the high standards of Porsche vehicles. Manufactured using heat-resistant rubber, reinforced steel, or braided lines, these components are designed for durability, leak prevention, and perfect fitment. Whether you’re maintaining a classic 911 or servicing a modern Cayman or Panamera, our manufacturer-quality oil hoses ensure reliable oil circulation and peak performance.
What Do Engine Oil Pipes and Hoses Do?
Oil pipes and hoses are critical for transporting pressurised oil through the engine’s lubrication and cooling circuits.
Core Functions:
- Carry
oil between the engine block, oil cooler, and filter housing.
- Maintain
consistent oil pressure for proper lubrication.
- Prevent
leaks and ensure stable oil flow under all conditions.
- Assist with cooling, transferring hot oil to radiators or heat exchangers.
Without functioning oil pipes and hoses, oil flow becomes inconsistent — leading to reduced lubrication, overheating, and potential engine damage.
Why Do Oil Pipes and Hoses Fail?
Over time, exposure to heat, pressure, and oil contamination causes hoses and pipes to weaken or deteriorate.
Common Causes of Failure Include:
- Age-related
hardening or cracking of rubber hoses.
- Corrosion
or fatigue in metal or braided lines.
- Loose
fittings or clamps leading to leaks.
- Oil
degradation that damages internal linings.
- Vibration and heat cycles, especially in performance engines.
Symptoms of failure include visible oil leaks, burning smells, low oil pressure, or warning lights — all of which indicate it’s time for inspection or replacement.
Why Replace Oil Pipes & Hoses?
Replacing damaged or leaking oil pipes ensures reliable lubrication and pressure regulation throughout your engine. Our high-quality, direct-fit replacements are designed to restore original flow characteristics, prevent leaks, and resist the extreme conditions found in performance driving.
Key Benefits:
- Restores correct oil pressure and flow.
- Prevents leaks and contamination.
- Improves lubrication and cooling efficiency.
- Constructed from durable, oil- and heat-resistant materials.
- Compatible with air-cooled and water-cooled Porsche models.
- Ideal for engine rebuilds, servicing, and preventive maintenance.
Precision oil hoses and pipes are essential for keeping your Porsche’s lubrication system performing at its best — ensuring reliability and longevity on road or track.
Highlights:
- Precision-engineered oil pipes and hoses for Porsche engines.
- High-strength, corrosion-resistant materials for long service life.
- Direct-fit replacements designed for leak-free operation.
- Improves lubrication reliability and oil pressure stability.
- Perfect for maintenance, upgrades, or full engine rebuilds.
