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.
Search Context
Search context: Many searches use terms like 'genuine' or 'OEM'. This part is a compatible replacement engineered to match original specifications. It is not a Porsche Genuine Part.

OEMatch Oil System & Pipes — Fit, Function, Confidence
OEMatch supplies oil system parts chosen for Porsche models, including pipes, hoses, fittings and related hardware. This selection supports repairs where correct routing, sealing and material resistance are essential to maintain oil temperature and prevent leaks across model ranges.
Available Types
- Metal oil cooler lines and rigid pipes for high-temperature routing
- Reinforced rubber hoses, bends and flexible connectors
- Seals, gaskets, unions and fittings for filter housings and cooler interfaces
Understanding OEMatch Oil System & Pipes
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil system & pipes. OE (Original Equipment) refers to parts matching original specifications for the oil system & pipes and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil system & pipes engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The oil system and its pipes route oil between the engine, oil cooler and filter, help control temperature and maintain stable pressure, and protect bearings, camshafts and seals from excessive heat and wear. Failures typically present as leaks, low oil pressure or overheating; correct diagnosis and use of parts that match original routing and sealing details reduce the risk of repeat faults. OEMatch catalogues thousands of Porsche part numbers and cross-references to assist identification of the right lines, hoses and fittings for repair or maintenance.
Benefits Include
- Restored oil circulation and temperature control for reliable lubrication
- Reduced risk of leaks and oil loss through correct sealing and fittings
- Materials selected to resist heat, oil exposure and corrosion
Why Oil System & Pipes Wear and Fail
- Heat and age causing cracking or work hardening of metal pipes
- Rubber hose degradation from prolonged exposure to oil and high temperatures
- Corrosion, impact damage or blockages from sludge and deposits
The Importance of Replacing with OEMatch Oil System & Pipes
Fitting the correct replacement lines and related parts preserves oil pressure, prevents leaks and helps maintain consistent engine temperature. Using parts that match original routing, sealing interfaces and material grades reduces the chance of premature failure and the need for repeat repairs, supporting long-term reliability and protecting costly engine components.
Advantages
- Direct-fit alternatives engineered to original-spec dimensions and tolerances
- Corrosion-resistant materials and reinforced hose constructions
- Quality fittings and sealing solutions to restore leak-free operation
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new seals or fasteners where specified; protect paintwork during work and check for correct routing and secure connections after initial running. If the vehicle includes hidden sensors or you are unsure, seek professional help.
