The oil pump / tandem pump seal helps prevent oil leakage from the pump mounting or sealing area. A correctly fitted seal supports engine oil system integrity, helps maintain clean engine bay conditions, and reduces the risk of oil seepage around the pump assembly.
Functions
• Replaces the oil pump / tandem pump seal
• Helps seal the pump mounting area
• Supports correct engine oil sealing
• Helps prevent oil leaks and seepage
• Suitable for oil pump, tandem pump, or engine sealing service
• Replaces hardened, flattened, cracked, swollen, or damaged original seals
• OE Match replacement for Porsche engine oil system repair.
Why Replace This Part?
Oil pump and tandem pump seals are exposed to engine heat, oil pressure, age, and vibration. Over time, the seal can harden, flatten, crack, swell, or lose its sealing ability. A worn or damaged seal may cause oil residue, oil drips, engine bay contamination, low oil level concerns, or failed inspection. Replacing the seal helps restore proper sealing and reliable oil system operation.
When to Replace This Part
• Oil is leaking or seeping from the oil pump / tandem pump area
• The pump has been removed for service or replacement
• The original seal is hardened, flattened, cracked, swollen, or damaged
• Engine oil residue is visible around the pump mounting area
• Engine sealing work is being carried out
• Preventative replacement is required during pump service
• The vehicle is undergoing Porsche 987.1, 987C.1, or 997.1 engine repair.
Where it fits on the car
This seal fits at the oil pump / tandem pump sealing area on Porsche 987.1 Boxster, 987C.1 Cayman, and 997.1 Carrera C2 / C4 models. It forms part of the engine oil sealing system.

OEMatch Oil Pumps & Gaskets — Durability, Sealing, Performance
OEMatch Oil Pumps & Gaskets are selected for Porsche models. They maintain oil circulation and pressure across the engine and correct sealing prevents leaks that can lead to component damage. The range supports service, rebuild and preventive maintenance for classic and modern Porsche engines.
Understanding OEMatch Oil Pumps & Gaskets
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil pumps & gaskets.
OE (Original Equipment) refers to parts matching original specifications for the oil pumps & gaskets and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil pumps & gaskets engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide range of Porsche components, from gaskets to suspension hardware, engine parts and interior trim. The catalogue includes over 4,000 individual part numbers and more than 8,700 cross-references and is continually updated. In Porsche engines the oil pump circulates pressurised oil to bearings, cams and other moving parts while gaskets and seals prevent leakage at pump covers, flanges and mating surfaces.
Benefits Include
- Restore and maintain correct oil pressure to protect bearings and journals.
- Prevent oil leaks with durable sealing materials and correct fit.
- Support long-term engine reliability during rebuilds and routine servicing.
Why Oil Pumps & Gaskets Wear and Fail
- Internal wear to gears, rotors or housings accelerated by contaminated oil.
- Clogged passages or relief valve faults causing loss of pressure.
- Gasket hardening, cracking or deformation from prolonged heat cycles and age.
The Importance of Replacing with OEMatch Oil Pumps & Gaskets
Timely replacement of the pump and associated seals preserves oil pressure and prevents contamination and overheating that can lead to major engine damage. Choosing correctly specified pumps and gaskets helps ensure consistent lubrication, reduces the risk of leaks and supports dependable operation across a wide range of Porsche engines and service scenarios.
Advantages
- Parts produced from heat- and wear-resistant materials suitable for engine environments.
- Options engineered as direct-fit replacements to match original mounting and sealing points.
- Coverage for classic and modern Porsche models to suit rebuilds, maintenance and performance work.
