Oil Pumps & Gaskets
Tandem & scavenge oil pumps kit for Porsche 987 Boxster, 987C Cayman, 996 and 997 models, supplied as a matched set of pumps and related components for the engine lubrication system.
What This Product Does This kit brings together the tandem and scavenge oil pumps used to move and return engine oil within the lubrication system. The pumps help maintain oil circulation around critical engine components and return oil from scavenge areas back to the main oil circuit for consistent lubrication.
Functions
- Circulates engine oil through internal galleries and components
- Scavenges oil from designated areas and returns it to the main oil supply
- Helps maintain stable oil pressure within the system
- Supports correct lubrication of bearings and other moving parts
Symptoms of Fault
- Low or fluctuating oil pressure readings
- Warning messages or lamps related to oil pressure (model dependent)
- Increased mechanical noise from the engine, especially when hot
- Signs of oil aeration or poor return flow in the lubrication system
Why Replacement Matters
Oil pumps are central to the engine’s lubrication system. When wear or internal damage reduces their ability to move oil or hold pressure, the risk of accelerated internal wear increases. During major engine work or a rebuild, these pumps are often renewed together so the scavenge and pressure circuits remain matched in condition. Using a dedicated kit helps ensure the correct parts are combined for the intended Porsche applications and reduces the chance of mixing incompatible components.

Engine Oil Pumps & Gaskets – Essential Components for Porsche Lubrication Systems
The engine oil pump is the heart of your Porsche’s lubrication system. It maintains the correct oil pressure and flow throughout the engine, ensuring that every moving component receives consistent lubrication for smooth operation and long-term durability. Paired with precision-engineered oil pump gaskets, these components prevent leaks and maintain pressure integrity — critical for performance and reliability.
At Design911, we stock a wide range of high-quality engine oil pumps and sealing gaskets designed for Porsche engines across all generations. Constructed from heat-resistant alloys and advanced sealing materials, these parts are built to deliver dependable oil circulation under demanding road and track conditions. Whether you’re performing a complete rebuild or servicing your engine, our manufacturer-quality oil pumps and gaskets ensure flawless performance and long-term protection.
What Do Engine Oil Pumps & Gaskets Do?
The oil pump works continuously to circulate engine oil, maintaining consistent pressure across all internal systems. The accompanying gaskets ensure that no oil escapes during this process.
Core Functions:
- Circulate
and pressurise oil to protect internal engine components.
- Prevent
metal-on-metal contact, reducing friction and wear.
- Maintain
optimal oil pressure during all operating conditions.
- Seal
the pump and associated components to prevent oil leaks.
- Support temperature regulation through stable oil flow.
Together, oil pumps and gaskets are the backbone of your engine’s lubrication and cooling efficiency.
Why Do Oil Pumps & Gaskets Fail?
Over time, wear, contamination, and heat cycles can compromise the performance of both the oil pump and its seals.
Common Causes of Failure Include:
- Internal
wear of pump gears or rotors from oil contamination.
- Loss
of pressure due to clogged oil passages or relief valve faults.
- Gasket
hardening or cracking from prolonged heat exposure.
- Oil
leaks caused by worn seals or improper installation.
- Low oil levels or infrequent maintenance, accelerating wear.
Symptoms of failure may include low oil pressure warnings, unusual engine noise, overheating, or oil leaks, all of which indicate the need for inspection and replacement.
Why Replace Oil Pump Components?
Replacing a failing oil pump and gasket is essential for maintaining correct oil pressure and preventing catastrophic engine damage. Our precision-engineered replacement parts are built for strength, longevity, and seamless integration into Porsche engines.
Key Benefits:
- Restores consistent oil pressure and flow.
- Prevents leaks and maintains optimal lubrication.
- Protects engine components from friction and overheating.
- Constructed from durable, heat-resistant materials.
- Direct-fit
compatibility for Porsche classic and modern models.
- Ideal for rebuilds, performance upgrades, or preventive maintenance.
Installing a new oil pump and gasket set ensures your Porsche’s engine operates at peak efficiency and reliability, whether for daily use or spirited driving.
Highlights:
- Precision-engineered oil pumps and sealing gaskets for Porsche engines.
- Ensures reliable oil circulation and pressure control.
- Prevents leaks with advanced sealing materials.
- Heat- and wear-resistant for long-term performance.
- Perfect for rebuilds, upgrades, or maintenance servicing.
- Compatible with air-cooled and water-cooled Porsche models.
