  • Porsche 997 MKII GT2 RS 2011-13

Diagram ref no 20

The turbocharger relies on a constant supply of clean, pressurised engine oil to lubricate and cool its high-speed bearings. Even the smallest oil leak at the supply connection can reduce lubrication efficiency, contaminate surrounding components and, if left unresolved, contribute to premature turbocharger wear. Replacing sealing rings whenever the oil supply line is removed is an essential part of good workshop practice.

Manufactured to Porsche's exacting standards, this Genuine Porsche seal ring offers the precise dimensions, material quality and sealing performance required for long-term reliability under the extreme temperatures and pressures experienced within the turbocharger oil circuit.

What Does the Turbocharger Oil Supply Seal Ring Do?

The seal ring creates a leak-proof connection between the turbocharger oil supply line and its mating components.

Its functions include:
Preventing engine oil leaks.

  • Maintaining correct oil pressure to the turbocharger.
  • Ensuring continuous lubrication of the turbocharger bearings.
  • Preventing contamination of surrounding engine components.
  • Supporting efficient turbocharger cooling.
  • Helping maintain long-term turbocharger reliability.

A correctly sealing oil feed connection is critical to the health of any turbocharged Porsche engine.

Why Does the Seal Ring Need Replacing?

Seal rings are designed as service items and should always be renewed once disturbed.

Common reasons for replacement include:

  • Removal of the turbocharger oil supply pipe.
  • Turbocharger replacement or rebuild.
  • Engine repair work.
  • Heat cycling causing the seal to harden.
  • Age-related loss of elasticity.
  • Oil seepage around the oil feed connection.
  • Preventative maintenance during engine servicing.

Replacing the seal ring is an inexpensive way to prevent oil leaks and protect expensive turbocharger components.

Symptoms of a Failing Seal Ring

Signs that the seal ring may require replacement include:

  • Oil leaks around the turbocharger oil supply connection.
  • Oil residue on surrounding engine components.
  • Burning oil smell after driving.
  • Light oil smoke from the engine bay.
  • Gradual loss of engine oil.
  • Visible deterioration of the sealing ring during servicing.

Any oil leak within the turbocharger lubrication system should be rectified immediately.

When Should the Seal Ring Be Replaced?

Replacement is recommended whenever:

  • The turbocharger oil feed pipe is removed.
  • A turbocharger is replaced or rebuilt.
  • Oil leaks are detected.
  • Engine repairs involve the oil supply circuit.
  • Performing preventative maintenance on the turbo lubrication system.

As with most sealing components, Porsche recommends fitting new seals rather than reusing old ones.

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.
