Oil lines may seem like minor components, but if they become defective, they can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, often functioning for years without issue. However, if a crack or break occurs, substantial amounts of oil can leak out—potentially draining the entire oil tank—and the affected component will no longer receive a reliable supply of engine oil.
To prevent such damage, it's recommended to replace aging oil hoses or lines before any issues arise. Full restorations generally involve replacing all oil lines to ensure reliability. Here, you can find high-quality replacement parts as described in the title.

Oil lines are often overlooked components, yet their failure can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, functioning reliably for years without drawing attention.
However, if a crack or break develops, substantial amounts of oil may leak—potentially draining the entire oil tank—leaving critical components without proper lubrication. To prevent such failures, it is advisable to replace aging oil hoses or lines at the first signs of wear.
In the context of full restorations, replacing all oil lines or hoses is a common and prudent practice to ensure long-term reliability.

The oil-supply pipe for the rear-mounted engine of classic Porsche 911 (Type 911/930) models from 1974-86. It replicates the original Porsche tube used to route oil from the thermostat to the oil cooler mount. Manufactured to match original equipment, the pipe guarantees correct oil flow, leak-free sealing, and reliable operation in this high-performance engine context.
Fits:
Porsche 911 1974 - 1986
Diagram Ref No 12
• Position on Vehicle: Oil supply pipe running along the under-floor or engine compartment from the front oil cooler/thermostat oil outlet toward the rear of the engine or oil sump/cooler.
• Applications: Ideal when the original oil-supply pipe is cracked, corroded, leaking, missing, kinked or shows signs of fatigue - crucial for restoring correct oil-pressure routing and engine reliability in classic 911/930 models.
In classic Porsche 911 and 930 engines, the oil-supply pipe carries engine oil under pressure towards the rear of the engine or oil-cooler circuit. A compromised pipe can allow oil leaks, pressure drop, decreased flow or contamination ingress - all of which can lead to reduced lubrication, bearing wear or engine damage. Replacing it with a correctly pipe restores the original oil-routing path and safeguards your engine.
When and why to replace:
• Visible oil leakage around the pipe or evidence of weepage along the routing.
• Corrosion, cracks or damage to the original pipe or its mounting brackets.
• The pipe has been removed or disturbed during prior engine works and re-use is not recommended.
• When restoring or rebuilding the engine oiling system on a classic 911/930.
• If oil pressure or flow issues are suspected and the pipe is part of the supply route.

Collapsible oil tube kit for Porsche 911, 964 and 993 engines. Supplied as an assembled return tube with associated sealing components, intended as a direct-fit replacement where the original oil return tube has aged or started to leak.
Overview & Construction
This kit uses a telescopic tube design to mirror the layout of the original return assembly between the cylinder head/oil galleries and the crankcase or external oil tank, depending on application. The collapsible section allows the tube to be installed without splitting the crankcase, while the included O-rings and circlip provide axial retention and a radial seal at each end. The construction is aimed at withstanding typical air-cooled engine temperatures, oil exposure and vibration so that the tube can maintain a stable sealing interface over repeated heat cycles.
- Collapsible/telescopic tube body for in-situ installation
- Sealing rings for both ends of the tube
- Circlip for tube location and retention (where applicable)
- Designed around original routing and connection points on 911, 964 and 993 engines
- One kit services a single oil return position; four tubes are normally used per engine
Operational Symptoms
- Oil drips or wetness along the oil return tubes or at their joints to the crankcase or cam carrier
- Oil residue on heat exchangers, undertrays or the lower engine casing
- Smell of hot oil after driving, sometimes with light smoke where oil contacts hot exhaust parts
- Progressive oil consumption not explained by external gaskets or top-end components
- Leaks that become more evident after long, hot runs when oil is at full temperature
Replacement Rationale
On older air-cooled engines, rigid or early-pattern tubes can harden, corrode or lose tension at the sealing interfaces, leading to external leaks or reduced return flow from the heads back to the sump or tank. Replacing a tired tube with a collapsible assembly allows the return line to be renewed with the engine in situ, restoring a defined oil path and fresh sealing surfaces at both ends. This helps maintain predictable oil circulation, reduces the risk of oil mist on hot components, and can be combined with other oil system work during rebuilds or top-end refreshes to minimise repeat access.
Compatibility
- Porsche 911 2.0L 1965–1969
- Porsche 911 1970–1989
- Porsche 964 1989–1994
- Porsche 993 1994–1998
Support & Advice
Check the condition of all four return tubes when the engine is accessible, as similar age and exposure often mean that multiple tubes show seepage at the same time. Confirm fitment against your specific model year and engine variant before installation, and ensure all sealing surfaces are clean, undamaged and free from old O-ring material prior to assembly.

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).

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.

OEMatch Oil Pipes & Hoses — Fit, Function, Confidence
Designed for Porsche models, these oil pipes and hoses route engine oil between the block, cooler and filter to preserve pressure, lubrication and cooling. OEMatch Oil Pipes & Hoses components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Materials include heat-resistant rubber, braided stainless-steel and formed metal lines
Available Types
- Rubber oil hoses for flexible connections
- Braided stainless-steel lines for higher-temperature use
- Rigid formed metal pipes for fixed routing
- Pre-formed feed and return lines for oil coolers
Understanding OEMatch Oil Pipes & Hoses
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil pipes & hoses.
OE (Original Equipment) refers to parts matching original specifications for the oil pipes & hoses and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil pipes & hoses engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Oil pipes and hoses carry pressurised oil between the engine, filter and cooler and help control temperature and flow. Their construction, routing and connections must suit each Porsche model’s layout. OEMatch catalogs thousands of part numbers and cross-references and continues to develop lines to help keep Porsche vehicles on the road.
Benefits Include
- Restores correct oil pressure and flow characteristics
- Reduces the risk of oil leaks and contamination
- Improves resistance to heat, oil and abrasion
Why Oil Pipes & Hoses Wear and Fail
- Age-related hardening, cracking or embrittlement of rubber hoses
- Corrosion, chafe or fatigue in metal or braided lines
- Loose fittings, clamps or damaged seals leading to leaks
- Oil contamination or degradation that attacks internal linings
The Importance of Replacing with OEMatch Oil Pipes & Hoses
Timely replacement of worn or damaged oil pipes and hoses restores reliable oil circulation and pressure regulation, which helps protect bearings, seals and other engine components from accelerated wear. Using correctly routed, material-appropriate lines reduces the chance of leaks and overheating and supports dependable operation across classic and modern Porsche engines during road use or rebuilds.
Advantages
- Options tailored to common Porsche layouts and oil systems
- Materials selected for heat and oil resistance
- Direct-fit replacements that simplify installation and reduce modification
Support & Advice
Fitting can appear straightforward but may require procedures such as correct torque settings and careful routing of hoses. If you lack the correct tools or model-specific knowledge, we recommend professional installation. Recheck fasteners and connections after initial running and observe for any diagnostic codes or oil leaks.
