Product Information
Collapsible oil tube kit, comes with the seals and circlip
This oil tube kit includes the collapsible pipe sections, necessary seals and the circlip required for a leak-free seal. Its design mirrors the original specification, ensuring correct fitment, alignment and sealing within the engine bay - making it suitable for rebuilds, restoration projects, or as a replacement for ageing/failed oil return tubes.

Fits:
Porsche 911 2.0L 1965 - 1969
Porsche 911 1970 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998

Diagram Ref No 36 and 37

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).

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.
  • 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.
  • Suitable for classic air-cooled and modern Porsche models.
