Oil tank breather hose. Porsche 964 - 96420714501
OE Match
96420714501/1
Product Information
As the upper of the two breather hoses leading from the top of the oil tank to the connecting piece, it plays a key role in maintaining correct hydrocarbon emission control and stable engine performance.
Fits:
Porsche 964 1989 - 1994
Diagram ref no 37
Designed to match the original hose in shape, length, and material, this replacement ensures a secure, leak-free connection and reliable vapor flow. Over time, factory hoses become brittle, soft, or oil-soaked, leading to vapor leaks, oil mist in the engine bay, or improper crankcase ventilation. Installing an fresh breather hose restores the integrity of the dry-sump ventilation circuit and helps maintain stable engine operation.
A degraded breather hose can lead to:
• Oil mist or residue in the engine bay
• Rough or unstable idle due to pressure imbalance
• Oil leaks caused by crankcase over-pressure
• Increased emissions and unpleasant odours
Replacing the breather hose keeps the dry-sump system operating properly and ensures a clean, leak-free engine compartment.

Product Information
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).
