Information
Camshaft Timing Chain. CLOSED TYPE.
OE Match camshaft timing chain - the primary chain that connects the crankshaft to the camshaft(s) and synchronises their rotation. It corresponds to Porsche OEM ref 993.105.529.00, which was used in Porsche 911 1965 - 1997 models.
Fits left or right. Sold each.
Fits:
Porsche 911 1965 - 1989
Porsche 964 1991 - 1993
Porsche 993 1994 - 1997
Diagram ref no 1
The camshaft timing chain is a critical engine component that maintains precise timing between the crankshaft and camshaft(s). This timing governs when the engine’s intake and exhaust valves open and close relative to piston position - a key factor in efficient combustion, engine power, emissions, and overall drivability. The chain connects the rotating crankshaft to the camshafts so that valve timing is mechanically linked and constant.
Function:
• Synchronises engine timing: Maintains crankshaft-to-camshaft rotation alignment
• Supports combustion efficiency: Ensures accurate valve events for intake and exhaust strokes
• Transfers mechanical drive: From crankshaft to camshaft drive mechanisms
• Withstands high loads: Engine torque and RPM forces over long service life.
Unlike timing belts, timing chains are metal-to-metal and designed for durability, although they can stretch or wear with high mileage or inadequate lubrication.
The timing chain is at the heart of the engine’s mechanical timing system. While chains are generally long-lasting, wear can occur due to mileage, heat cycling, lubrication contamination, or slack from chain stretch. A worn or stretched timing chain can lead to:
• Incorrect valve timing
• Engine noise (rattle at startup or idle)
• Reduced power and efficiency Irregular idle and misfires
• Potential catastrophic engine damage if timing deviates too far.
Replacing a worn chain with an OE Match unit restores correct timing precision and helps protect major internal engine components.
When to replace. Install a new timing chain when:
• There is timing chain noise (rattling) at startup or idle
• Chain tensioner or guides are being replaced
• Engine has high mileage with original timing components
• You are performing engine rebuild, top-end service, or head removal
• Diagnostic codes indicate timing inconsistencies

Information
Chain tensioner adjuster.
The OE Match timing chain adjuster (also known as a chain tensioner adjuster) is an engine timing component used in Porsche 964 and Porsche 993 models. These adjusters help maintain the correct tension in the engine’s timing chain system, ensuring accurate synchronization between the crankshaft and camshafts.
Fits:
Porsche 964 1989 - 1994
Porsche 964 Turbo 1993 - 1994 3.6L
Porsche 964 RS
Porsche 993 1994 - 1998
Diagram Ref no 9 and 10.
The OE Match versions correspond to Porsche reference numbers 96410507900 / 96410507901 (left side) and 96410508000 / 96410508001 (right side) and are designed as direct replacements for the original factory components.
The timing chain adjuster is part of the camshaft timing system used in air-cooled Porsche flat-six engines. The component works together with the timing chain tensioner and guide rails to keep the chain correctly tensioned as the engine operates.
Each engine uses separate left and right adjusters, depending on the cylinder bank.
The chain adjuster maintains the proper position and tension of the timing chain, preventing slack or vibration within the timing assembly. By keeping the chain properly tensioned, it helps ensure precise valve timing and smooth engine operation.
Replacing worn adjusters helps prevent timing chain noise, improves reliability and protects critical engine components from excessive wear.
Function
• Timing Chain Tension Control: Maintains proper tension in the camshaft timing chain
• Valve Timing Accuracy: Ensures correct synchronization between crankshaft and camshafts
• Engine Protection: Prevents chain slack, vibration and premature wear
• Smooth Operation: Helps eliminate chain rattle and timing instability
Timing components are constantly exposed to engine heat, oil pressure and mechanical load. Over time adjusters can wear or lose precision, leading to timing chain noise, unstable valve timing or reduced engine performance. Replacing worn chain adjusters ensures proper tensioning of the timing chain and helps protect the engine’s internal components.
Consider replacing the timing chain adjuster when:
• Timing chain rattle or knocking noise appears
• Performing timing chain or tensioner replacement
• During engine rebuild or top-end service
• High-mileage engines with original timing components

Slide rail for timing chain. LEFT
The guide rail provides a stable pathway for the timing chain as it connects the crankshaft and camshaft, maintaining correct alignment under heat, load, and rotational forces.
Fits:
Porsche 964 1989 - 1994
Porsche 993 1995 - 1998
Diagram Ref No 16.
• Application: Timing chain guide (straight/left) used in the timing system on 964 and 993 models to direct the chain path and maintain tension.
The guide rail helps support the timing chain’s smooth movement, reducing slack and guiding it over sprockets and tensioners. It works hand-in-hand with the tensioner to maintain proper chain tension, which is critical for accurate valve timing, smooth engine operation, and longevity of the timing chain system. Without a properly functioning guide rail, timing chain wear accelerates, potentially leading to engine misalignment or failure.
Installed in the engine block or timing cover pathway, this rail contacts the timing chain and provides a friction-resistant surface that helps the chain track correctly as the engine runs. Over time, original rails can wear, fracture, or lose their smooth surface, increasing chain wear and noise. An OE Match guide rail restores the correct surface finish and dimensions for reliable chain guidance and engine timing control.
The timing system in your Porsche engine relies on precise chain routing and tension to synchronize the crankshaft and camshafts. A worn or damaged guide rail can lead to:
• Excessive chain wear and noise
• Incorrect valve timing
• Accelerated wear on sprockets and tensioners
• Potential engine performance issues or damage
Replacing worn guide rails restores proper chain guidance, reduces engine noise, and helps maintain reliable engine timing - especially important in high-performance engines where precision is critical.
Replace the timing chain guide rail if you notice:
• Rattling or unusual chain noise from the timing cover area
• Visible wear on the rail surface
• Chain slack or timing inconsistencies
• During timing chain or tensioner replacement
• After significant mileage or engine overhaul work

About Chains & Tensioners
OEMatch Chains & Tensioners — Fit, Function, Confidence
Timing chains, guides and tensioners keep a Porsche engine’s valve timing correct across a wide range of operating conditions. This group of parts is specified for durability and stable timing under load; replacement is common during major service or when symptoms such as rattle, rough idle or diagnostic codes point to timing system wear.
Available Types- Timing chains for petrol engines
- Tensioner kits, hydraulic and mechanical
- Chain guides and rails
- Complete timing chain kits with seals and fasteners
Understanding OEMatch Chains & Tensioners
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original chains & tensioners.
OE (Original Equipment) refers to parts matching original specifications for the chains & tensioners and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM chains & tensioners engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. In practice, the timing chain system synchronises the crankshaft and camshafts, the guides control chain run and alignment, and the tensioner maintains correct chain tension to prevent slack, noise and timing drift under varying oil pressure and temperature conditions.
