Information
Oil tube seal for crankcase distribution oil pipes.
Round oil return tube O-ring used at the outer ends of the crankcase oil distribution / return tubes. Each tube uses two seals, and a complete engine typically requires multiple O-rings depending on tube type and configuration (often eight per engine on many 911/964/993 applications).
Sold each.
Fits:
Porsche 911 1970 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
Diagram ref no 14.
This seal provides a leak-tight joint between the oil return tube and the crankcase or associated oil galleries. By sealing the tube ends, it:
• Prevents engine oil leaks at the tube junctions.
• Helps maintain correct oil circulation and system pressure.
• Keeps oil off the heat exchangers, exhaust and underside of the engine, reducing smells, smoke and contamination.
With age, heat and constant oil exposure, original O-rings can harden, flatten, crack or shrink. When they fail:
• Oil begins to weep or drip from the crankcase / tube junctions.
• The underside of the engine, heat exchangers and exhaust can become oil-soaked, causing burning smells and smoke.
• You may see oil spots under the car and gradual oil loss between services.
Replacing tired seals is a low-cost, high-impact fix that significantly reduces leaks and keeps the engine bay cleaner.
When to Replace
Consider replacing these oil tube seals if:
• You see oil leaks or dampness around the oil return tubes or crankcase unions.
• The engine is undergoing an oil return tube replacement (solid or collapsible).
• You’re performing an engine refresh, top-end rebuild, or major oil system service.
• The car shows persistent oil drips on the floor despite other seals being renewed.

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).

Designed to maintain proper oil flow throughout the engine lubrication system, this oil tube helps ensure critical engine components receive the oil supply necessary for cooling, lubrication and long-term durability.
What This Product Does:
- Transfers engine oil between key lubrication system components.
- Maintains consistent oil flow and oil pressure.
- Supports lubrication of critical engine components.
- Helps dissipate heat through the engine oil circuit.
- Features a collapsible design for simplified installation.
- Includes replacement seals for a complete repair solution.
- Helps maintain the integrity and efficiency of the engine lubrication system.
Symptoms Of Wear Or Failure:
- Visible engine oil leaks.
- Oil drips beneath the vehicle.
- Low engine oil level between services.
- Oil residue around oil line connections.
- Reduced engine oil pressure.
- Oil warning light illumination.
- Burning oil smell from oil contacting hot engine components.
- Corrosion, cracking or physical damage to the oil tube.
- Signs of deteriorated or leaking seals.
Why Replacement Matters:
- Engine oil tubes operate under constant exposure to heat, pressure, vibration and environmental contaminants. Over time, oil lines can corrode, crack, deform or develop leaks around joints and sealing surfaces. Ageing seals may also lose elasticity, resulting in oil seepage or pressure loss.
- A leaking or damaged oil tube can reduce oil pressure and lubrication efficiency, potentially leading to accelerated engine wear, overheating and costly engine damage. Even small oil leaks can worsen over time, creating reliability issues and increasing maintenance costs.
- Replacing a worn oil tube with an OE Match collapsible CNC alloy assembly restores proper oil circulation and system integrity. The collapsible design simplifies installation while the supplied seals help ensure a leak-free repair. Manufactured to OE standards, this replacement provides excellent durability, reliable performance and long-term protection for your Porsche engine.

- Supports lubrication of critical engine parts.
- Assists with engine cooling through oil circulation.
- Helps ensure efficient operation of the lubrication system.
- Provides a secure, leak-resistant oil passage.
- Supports long-term engine reliability and performance.
Symptoms Of Wear Or Failure:
- Visible engine oil leaks.
- Oil drips beneath the vehicle.
- Low engine oil level between services.
- Oil residue around oil line connections.
- Reduced engine oil pressure.
- Oil pressure warning light illumination.
- Burning oil smell from oil contacting hot engine components.
- Corrosion, cracking or physical damage to the oil tube.
- Signs of oil seepage at connection points.
Why Replacement Matters:
- Engine oil tubes operate in demanding conditions and are continually exposed to heat, pressure fluctuations, vibration and environmental contaminants. Over time, corrosion, fatigue, physical damage or deteriorated sealing surfaces can lead to leaks and reduced lubrication system efficiency.
- A damaged oil tube can result in oil loss, reduced oil pressure and insufficient lubrication of critical engine components. If left unresolved, oil leaks can contribute to accelerated engine wear, overheating and potentially severe engine damage. Even minor leaks can worsen over time and create reliability and maintenance concerns.
- Replacing a worn or damaged oil tube restores proper oil circulation and helps maintain the integrity of the engine lubrication system. An OE Match replacement provides factory-style fitment, dependable performance and long-term durability, ensuring reliable oil delivery and continued protection for your Porsche engine.
