Timing Chain / Oil Pump Drive.
The IWIS Timing Chain / Oil Pump Drive is a replacement internal engine drive-chain component for compatible Porsche applications. Designed for the engine's oil pump drive system, it transfers mechanical rotation through the chain drive to help ensure continuous operation of the oil pump while the engine is running.

Fits:
  • Porsche 957 Cayenne 3.0L Diesel 2007-10
  • Porsche 958 Cayenne V6 3.0L Diesel (245Hp) 2011

Diagram Ref No 30

Reliable oil pump drive is essential because the lubrication system must continuously circulate engine oil to bearings, rotating assemblies, timing components and other internal surfaces. Excessive chain wear, elongation or damage can compromise the drive system and, in severe cases, contribute to loss of oil circulation and serious engine damage.  

What This Product Does:

This chain forms part of the mechanical drive system responsible for operating the engine oil pump.

It transfers rotational movement through the engine's drive system to the oil pump, allowing the pump to circulate lubricating oil throughout the engine.

Its function helps support:

  • Reliable oil pump operation
  • Continuous engine oil circulation
  • Correct lubrication of internal engine components
  • Protection of crankshaft and connecting-rod bearings
  • Lubrication of camshaft and valvetrain components
  • Lubrication of timing-system components
  • Reduction of internal friction and wear
  • Reliable long-term engine operation

The chain itself does not generate oil pressure. It provides the mechanical drive required for the oil pump to operate.

Symptoms Of Wear Or Failure:
Oil pump drive chains are designed for long service life, but wear can develop due to mileage, lubrication problems, contamination or deterioration of associated components.

Possible symptoms include:

  • Metallic rattling or clattering
  • Chain noise from the drive area
  • Excessive chain slack
  • Chain elongation
  • Visible chain wear or damage
  • Abnormal sprocket wear
  • Excessive movement within the chain drive
  • Low oil-pressure warning
  • Oil-pressure related fault messages
  • Abnormal engine noise associated with inadequate lubrication
  • Metal particles or debris in the engine oil or oil filter

Some chain-drive problems may provide limited warning before becoming serious, so confirmed excessive wear should be addressed promptly.

Why Replacement Matters:
The oil pump drive chain performs an important role in maintaining reliable engine lubrication.

Replacing a confirmed worn, elongated or damaged IWIS Timing Chain / Oil Pump Drive can help:

  • Restore dependable mechanical drive to the oil pump
  • Maintain reliable engine oil circulation
  • Reduce excessive chain slack
  • Reduce abnormal chain noise
  • Correct excessive chain elongation
  • Protect associated sprockets and drive components
  • Reduce the risk of oil pump drive failure
  • Support correct engine lubrication
  • Protect expensive internal engine components

Because the lubrication system is critical to engine survival, deterioration within the oil pump drive should not be ignored.

About Oil Pumps & Gaskets

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.
