What is an Engine Timing Chain?
The timing chain is a vital component in an internal combustion engine, responsible for synchronizing the rotation of the crankshaft and camshafts. This precise coordination ensures that engine valves open and close at the correct times during each cylinder’s intake and exhaust strokes, allowing for smooth performance and efficiency.
While designed to last the lifetime of the engine, timing chains can wear, stretch, or become damaged. A worn chain can alter engine timing, strain the tensioners, and, if left unaddressed, lead to catastrophic engine damage and costly repairs.
Why Replacement Matters:
The timing chain system is crucial for synchronising crankshaft and camshaft timing. Mis-timed engine can lead to loss of power, increased emissions or catastrophic internal damage. Over time chains stretch, guides wear and tensioners degrade, compromising timing accuracy. A full timing chain replacement restores correct timing, enhances engine reliability and protects against future costly repairs.
When and why to replace:
• Audible chain rattle on start-up or at idle.
• Engine mis-timing faults, camshaft sensor codes or rough running.
• Visible chain guide wear or damaged tensioners during disassembly.
• High-mileage engine (> 80,000–100,000 km) where original timing system is aging.
• During an engine rebuild or major service when access to timing system is available.

TIP! If you detect a chain clap or rattling noise in the engine, your timing chain may be worn or stretched and needs replacing. Each car has two.
This OE Match camshaft timing chain is a replacement split-type timing chain for air-cooled Porsche 911 engines. It is designed to match the original-style fit and function, helping maintain correct camshaft timing and reliable valve train operation.
The camshaft timing chain links the crankshaft drive to the camshaft drive system, ensuring that the camshafts rotate in precise timing with the engine crankshaft. This correct timing allows the engine valves to open and close at the right moment for smooth running, correct combustion, and dependable engine performance.
Functions
• Drives the camshaft timing system
• Helps keep crankshaft and camshaft timing synchronised
• Supports correct valve opening and closing timing
• Helps maintain smooth engine running and performance
• Provides a split-type design for easier installation during service
• Replaces stretched, worn, noisy, or damaged timing chains
• OE Match replacement for engine rebuilds and timing chain repairs
Why Replace This Part?
Camshaft timing chains are subject to constant load, heat, oil exposure, and high-speed operation. Over time, the chain can stretch, wear, become noisy, or affect accurate cam timing. A worn timing chain may cause rattling noises, poor running, incorrect valve timing, or reduced engine performance. Replacing the chain during engine service or rebuild helps restore timing accuracy and long-term reliability.
When to Replace This Part
• The timing chain is stretched, worn, noisy, or damaged
• There is rattling from the cam chain housing area
• Camshaft timing is being reset or corrected
• The engine is being rebuilt or overhauled
• Chain ramps, sprockets, or tensioners are being replaced
• The timing chain covers or camshaft housings have been removed
• As preventative replacement during major engine service.
Where it fits on the car
This timing chain fits inside the engine timing chain housing, forming part of the camshaft drive system. It runs between the crankshaft-driven intermediate shaft sprocket and the camshaft sprocket assembly, depending on the engine layout.

What This Product Does:
- Connects and secures the ends of the engine timing chain.
- Allows installation or repair of the timing chain assembly.
- Maintains continuous timing chain operation.
- Supports accurate camshaft and crankshaft synchronisation.
- Helps ensure precise valve timing throughout the engine's operating range.
- Contributes to smooth engine performance and reliability.
Symptoms Of Wear Or Failure:
- Timing chain noise or rattling.
- Excessive timing chain slack.
- Visible wear or damage to the link components.
- Accelerated timing chain wear.
- Inconsistent engine timing.
- Reduced engine performance.
- Difficulty maintaining proper chain tension.
- Potential timing chain failure in severe cases.
Why Replacement Matters:
- The timing chain system is one of the most critical components within the engine, controlling the relationship between the crankshaft and camshafts. Although small, the split link plays a vital role in maintaining the integrity of the entire timing chain assembly.
- Over time, wear, corrosion, fatigue or damage during servicing can compromise the strength of the split link. A weakened or damaged link may accelerate chain wear or increase the risk of timing chain failure. Because timing-related failures can result in significant engine damage and costly repairs, replacing worn timing chain components during maintenance or engine rebuilds is highly recommended.
