This OE match tandem oil pump is a direct replacement for the original Porsche component fitted to selected 987 Boxster, 987 Cayman, and 997.1 Carrera models equipped with M96/M97 flat-six engines. The tandem oil pump circulates engine oil through the lubrication system while also supporting vacuum functions within the engine. It helps maintain proper oil pressure, lubrication, and engine reliability under all operating conditions.
Fits:
Porsche 987 Boxster / Boxster S 2005 - 2008
Porsche 987C Cayman / Cayman S 2006 - 2008
Porsche 997.1 C2 / C4 / C2S 2005 - 2008 Cabrio/Coupe

Installed within the engine lubrication system, the tandem pump combines oil scavenging and vacuum pump functions into a compact assembly. It helps circulate engine oil through critical lubrication passages while also supporting crankcase ventilation and vacuum-related engine systems. The pump is particularly important for maintaining oil pressure and preventing oil starvation during spirited driving or high engine loads.
Function
• Circulates engine oil through lubrication system
• Maintains correct engine oil pressure
• Supports oil scavenging and crankcase vacuum functions
• Protects internal engine components from oil starvation
• Ensures reliable lubrication under high engine loads
A worn or failing tandem oil pump can lead to low oil pressure, inadequate lubrication, engine noise, or severe engine damage caused by oil starvation. Internal wear or pressure loss may also affect vacuum system operation and overall engine efficiency. Replacing the pump restores correct oil circulation and helps protect critical engine components from premature wear.
When to replace
• Low or fluctuating oil pressure
• Oil pressure warning light illuminated
• Unusual engine noise or ticking
• During engine rebuild or lubrication system service
• Evidence of internal oil pump wear or contamination

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.
