Timing Chain / Oil Pump Drive. Porsche 957 / 958 Cayenne Diesel 3.0L V6  ❭  958109465

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

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.
