OEMatch supplies a wide selection drawn from a catalogue of over 4,000 individual part numbers and more than 8,700 OE cross-references, covering tanks, fittings, caps, hoses and mounting hardware. OEMatch Oil Tank & Parts components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types
- Aluminium engine oil tanks and reservoirs
- Oil tank caps, breather assemblies and sealing gaskets
- Feed, return and breather hoses with fittings
- Mounting brackets, seals, clamps and tank fittings
Understanding OEMatch Oil Tank & Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil tank & parts.
OE (Original Equipment) refers to parts matching original specifications for the oil tank & parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil tank & parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The oil tank acts as the reservoir in a dry-sump lubrication system, keeping oil separate from the crankcase to prevent aeration and to ensure steady pressure during heavy cornering, braking or acceleration. Supporting components such as caps, breathers, hoses and fittings route oil correctly, maintain seals and allow the system to vent and return oil without foaming. Materials are chosen for heat resistance and corrosion protection to withstand the operating environment.
Benefits Include
- Restores stable oil pressure and consistent circulation
- Reduces risk of aeration and oil starvation under high G-loads
- Improves oil cooling and helps protect engine components
Why Oil Tank & Parts Wear and Fail
- Corrosion or internal contamination from moisture and sludge
- Cracks, punctures or impact damage from vibration or debris
- Worn seals, damaged caps or degraded hoses causing leaks
- Blocked breathers or feed lines restricting oil flow
The Importance of Replacing with OEMatch Oil Tank & Parts
Worn or leaking oil tanks and associated parts compromise lubrication and can lead to fluctuating oil pressure, overheating and increased wear. Replacing degraded tanks, seals and hoses restores proper oil management, prevents contamination and helps maintain engine longevity and reliability for road and motorsport use. Choosing correctly sized, well-sealed components reduces the chance of leaks and avoids secondary damage.
Advantages
- Durable, heat-stable materials selected for long service life
- Designed for fit with Porsche mounting points and system layouts
- Suitable for restorations, rebuilds and performance installations
