Information
Tandem oil pump
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
