The IWIS Timing Chain is a replacement internal engine timing component for compatible Porsche applications. It forms part of the engine's mechanical timing drive and helps maintain the precise synchronisation required between associated rotating and valve-train components.

Diagram Ref No 27
Timing chains are designed for extended service life, but they operate continuously whenever the engine is running. Repeated mechanical loading, friction, heat and lubrication conditions can gradually cause wear to the chain pins, links and contact surfaces. Associated guides, tensioners and sprockets can also deteriorate over time.
As wear develops, the chain's effective length can increase, creating excessive slack and potentially affecting timing accuracy. Severe deterioration can allow the chain to jump, derail or fail, creating a risk of significant internal engine damage.
What This Product Does:
The timing chain transfers rotational movement through the engine timing system while maintaining the required mechanical relationship between associated components.
Depending on the specific engine configuration, it helps support:
- Accurate engine timing
- Correct camshaft operation
- Correct valve timing
- Reliable mechanical synchronisation
- Consistent rotational drive
- Smooth engine operation
- Stable combustion
- Consistent power delivery
Correct chain tension, adequate lubrication and accurate engagement with the associated sprockets are essential for dependable timing-system operation.
Symptoms Of Wear Or Failure:
Possible symptoms of timing-chain or associated timing-system wear include:
These symptoms do not automatically mean the chain itself has failed. Guides, tensioners, sprockets, lubrication problems and other engine faults can produce similar symptoms, making correct diagnosis important.
Why Replacement Matters:
The timing chain is a critical internal engine component. Once excessive wear, elongation or physical damage has been confirmed, replacement is important for restoring dependable timing-system operation.
Replacing a worn IWIS Timing Chain can help:
- Restore reliable mechanical synchronisation
- Maintain accurate engine timing
- Restore correct chain operation
- Reduce excessive chain slack
- Reduce abnormal timing-chain noise
- Maintain reliable sprocket engagement
- Protect timing-chain guides
- Protect associated sprockets
- Reduce the risk of timing deviation
- Reduce the risk of the chain jumping
- Reduce the risk of chain derailment
- Support smooth engine operation
- Protect expensive internal engine components
Continuing to operate an engine with a confirmed timing-chain problem may allow deterioration to progress and substantially increase the cost of the eventual repair.
