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.

What This Product Does
The toothed sleeve forms part of the engine oil pump assembly. It is an individual component rather than a complete pump or gasket set, making it relevant to oil pump servicing and engine rebuild work where inspection identifies a need for renewal.
Technical Details
- Brand: Original Porsche.
- Part references: 94410716102 and 94410716104.
- The supplied 968 engine lubrication diagram identifies 94410716104 as the toothed sleeve.
- Diagram application: Porsche 968 1992–95, engines M44.43/44.
- Exploded-diagram position: item 3.
Symptoms of Fault
Lubrication-system concerns can include an oil-pressure warning, unusually low pressure when hot, delayed pressure build-up or abnormal engine noise. These symptoms do not establish that the sleeve is faulty; pressure testing and inspection are needed to identify the cause before replacing components.
Why Replacement Matters
Renewal is appropriate when inspection confirms that the existing sleeve is worn or damaged. During pump servicing, assess the associated seals and supporting components separately so that other sources of leakage or pressure loss are not overlooked.
FAQs
Does this include the complete oil pump?
No. The product is the toothed sleeve; the diagram identifies the pump and sealing components separately.
What should I check on an early 944?
Confirm the 2.5L application against the stated chassis cut-offs, rather than selecting by model year alone.
Does low oil pressure prove the sleeve needs replacing?
No. Verify actual pressure and investigate the lubrication system before deciding which parts require renewal.
