Collapsible oil tube kit. Porsche 911 / 964 / 993

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

• 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).
