Oil lines may seem like minor components, but if they become defective, they can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, often functioning for years without issue. However, if a crack or break occurs, substantial amounts of oil can leak out—potentially draining the entire oil tank—and the affected component will no longer receive a reliable supply of engine oil.

To prevent such damage, it's recommended to replace aging oil hoses or lines before any issues arise. Full restorations generally involve replacing all oil lines to ensure reliability. Here, you can find high-quality replacement parts as described in the title.

Oil lines are often overlooked components, yet their failure can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, functioning reliably for years without drawing attention.

However, if a crack or break develops, substantial amounts of oil may leak—potentially draining the entire oil tank—leaving critical components without proper lubrication. To prevent such failures, it is advisable to replace aging oil hoses or lines at the first signs of wear.

In the context of full restorations, replacing all oil lines or hoses is a common and prudent practice to ensure long-term reliability.

Product Information
Brass long intake oil pipe. Flows length of car.
The oil-supply pipe for the rear-mounted engine of classic Porsche 911 (Type 911/930) models from 1974-89. It replicates the original Porsche tube used to route oil from the thermostat to the oil cooler mount. Manufactured to match original equipment, the pipe guarantees correct oil flow, leak-free sealing, and reliable operation in this high-performance engine context.

Fits:
Porsche 911 1974 - 1986

Diagram Ref No 12

•  Position on Vehicle: Oil supply pipe running along the under-floor or engine compartment from the front oil cooler/thermostat oil outlet toward the rear of the engine or oil sump/cooler.

•  Applications: Ideal when the original oil-supply pipe is cracked, corroded, leaking, missing, kinked or shows signs of fatigue - crucial for restoring correct oil-pressure routing and engine reliability in classic 911/930 models.

In classic Porsche 911 and 930 engines, the oil-supply pipe carries engine oil under pressure towards the rear of the engine or oil-cooler circuit. A compromised pipe can allow oil leaks, pressure drop, decreased flow or contamination ingress - all of which can lead to reduced lubrication, bearing wear or engine damage. Replacing it with a correctly pipe restores the original oil-routing path and safeguards your engine.

When and why to replace:
Visible oil leakage around the pipe or evidence of weepage along the routing.
Corrosion, cracks or damage to the original pipe or its mounting brackets.
The pipe has been removed or disturbed during prior engine works and re-use is not recommended.
When restoring or rebuilding the engine oiling system on a classic 911/930.
If oil pressure or flow issues are suspected and the pipe is part of the supply route.

Kit Contents: Collapsible oil tube(s), required seals, O-rings/circlip for sealing - sold per tube, 4 required per engine per manufacturer’s recommendation.

 Recommended Use: Replacement during engine rebuilds, oil system refurbishment, or whenever original oil return lines show signs of age - cracking, leaks, oil seepage or pressure loss.

Collapsible oil tube kit:
  Provides a sealed, flexible return path for engine oil from the heads/galley back to the sump or oil tank.
  Allows for thermal expansion, engine movement, and vibration, reducing stress on hard oil lines and preventing fractures or leaks.
  Maintains correct oil circulation and pressure, ensuring effective lubrication and cooling of the engine even under load or temperature variation.
  Replaces brittle, corroded, cracked or otherwise degraded original tubes - restoring reliable oil return and system integrity.

Original rigid or old oil return tubes often suffer from material fatigue, hardening, cracking, or corrosion after many years and thermal cycles. A failing oil return tube can lead to:
  Oil leaks - risking oil starvation, contamination or engine damage
•  Reduced oil return flow - causing poor lubrication, overheating or premature engine wear
  Pressure variances - resulting in oil pressure instability or sump starvation under load
  Safety and reliability issues - a failing return path can lead to catastrophic engine damage.

Replacing with a correctly spec’d  collapsible tube ensures proper oil circulation, reliable return flow, leak-free sealing, and long-term engine reliability - essential for preserving performance and longevity on 911 / 964 / 993 engines (and compatible layouts).

Porsche 911 - 1969 to 1989

Please note 
For cars (1969 to 1973) the 1974-1989 style factory external oil thermostat must be used

Our proprietary design finned oil lines directly replace the factory lines that connect the external thermostat to the front fender mounted oil cooler.

Elephant Racing Purge Valve
No more partial oil changes. Built-in valve lets you evacuate the oil cooler and lines using compressed air. A quick blast forces dirty oil from the lines and cooler into the oil tank. Removes 1-2 quarts the engine and tank drain plugs leave behind.

Brass construction for corrosion resistance and full-flow high-quality fittings make Elephant Racing oil lines the choice solution. The lines are formed perfectly – just like OEM.

  • Substantial temperature reduction
  • Purge valve clears dirty oil from system
  • Easy bolt-on installation
  • No duct work, sits in air stream under car
  • OEM Fit
  • Light weight
Custom packaging

As shown in the cutaway, cooling fins are formed directly on the oil lines. The fins yield a four-fold increase in heat-dissipating surface area. The combined length of two lines is about 17 feet and with fins they become a giant oil cooler.

Our proprietary finned oil lines dissipate more heat.

A true bolt-in replacement that connects directly to the factory fittings, they can be used in combination with factory or aftermarket fender and valance mounted coolers.

About Oil Pipes & Hoses

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.

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.
