Manufactured to OE specifications for accuracy, fit and durability, this standard-type tensioner spacer is designed to withstand the demanding operating conditions found within the engine timing system. It is an ideal replacement during timing chain service, tensioner repairs or complete engine rebuilds.
What This Product Does:
- Maintains correct spacing and positioning within the timing chain tensioner assembly.
- Supports proper alignment of tensioner components.
- Helps ensure consistent timing chain tension.
- Contributes to smooth operation of the timing chain system.
- Reduces unnecessary wear on timing components.
- Supports accurate valve timing and engine performance.
Symptoms Of Wear Or Failure:
- Timing chain rattling or excessive chain noise.
- Inconsistent timing chain tension.
- Accelerated wear of tensioner components.
- Increased timing system vibration.
- Premature wear of timing chains and guide rails.
- Excessive movement within the tensioner assembly.
- Poor timing system performance during engine operation.
- Increased risk of timing-related component wear.
Why Replacement Matters:
- Although small in size, the tensioner spacer plays a critical role in maintaining the correct geometry and operation of the timing chain tensioner assembly. Continuous exposure to engine vibration, oil circulation, heat cycles and mechanical loads can contribute to wear over time, particularly during high-mileage use or engine rebuilds.
- A worn or incorrectly fitted spacer can affect tensioner alignment and chain control, potentially increasing wear on the timing chain, guide rails and tensioner components. Maintaining the integrity of every timing system component is essential for preserving accurate valve timing and long-term engine reliability.

Information
Timing chain - OPEN Type
This OE Match timing chain is an open-type replacement camshaft timing chain for Porsche 996 and 986 Boxster engines. It is designed to match the original-style fit and function, helping maintain correct valve timing and reliable engine operation.
2 per engine. Sold each.
Fits:
Porsche 996 3.4L C2/C4 1998 - 2001
Porsche 986 Boxster 1997 - 2004
Diagram Ref No 26
The timing chain links the crankshaft and camshaft drive system, keeping the camshafts synchronised with engine rotation. This ensures the intake and exhaust valves open and close at the correct time, supporting smooth running, efficient combustion, and dependable engine performance.
Functions
• Drives the camshaft timing system
• Keeps crankshaft and camshaft timing synchronised
• Supports correct intake and exhaust valve timing
• Helps maintain smooth engine running and performance
• Replaces stretched, worn, noisy, or damaged timing chains
• Open-type design for service and engine rebuild applications
• OE Match replacement for timing chain repair or engine overhaul.
Why Replace This Part?
Timing chains are exposed to constant load, oil, heat, and high-speed operation. Over time, the chain can stretch, wear, become noisy, or affect accurate camshaft timing. A worn timing chain may cause rattling noises, poor running, timing faults, reduced performance, or engine management warning lights. Replacing the chain helps restore timing accuracy and supports long-term engine reliability.
When to Replace This Part
• The timing chain is stretched, worn, noisy, or damaged
• There is rattling from the timing chain area
• Camshaft timing faults or related diagnostic codes are present
• The engine is being rebuilt or overhauled
• Chain guides, tensioners, sprockets, or rails are being replaced
• The timing system has been dismantled for repair
• As preventative replacement during major engine service
Where it fits on the car
This timing chain fits inside the engine timing chain system, forming part of the camshaft drive assembly. It runs within the engine timing case area and works with the chain guides, tensioners, sprockets, and camshaft drive components.

Information
Engine timing chain. CLOSED TYPE.
OE Match replacement engine timing chain - also referred to as the camshaft/intermediate shaft timing chain - designed to replicate the original Porsche timing chain used in the engine timing drive system of early 911 (996) and Boxster engines.
2 per engine. Sold each.
Fits:
Porsche 996 3.4L C2/C4 1998 - 2001
Porsche 986 Boxster 1997 - 2004
Diagram Ref No 26.
The timing chain ensures precise mechanical synchronization between critical rotating components of the engine - primarily the crankshaft and camshafts (and in some layouts, the intermediate shaft). It maintains the correct timing of valve opening and closing events relative to piston position, which is vital for efficient combustion, smooth engine operation, and proper power delivery.
Function:
• Synchronises rotation of the crankshaft and camshafts
• Maintains correct valve timing for intake and exhaust events
• Transfers mechanical drive through intermediate gears/shafts
• Supports reliable engine performance and emissions control.
A worn or elongated timing chain can cause timing errors, engine noise, rough running, or in more severe cases, engine damage if the timing relationship is lost.
The timing chain is a critical engine component. Over long service intervals and high mileage, the chain can stretch or wear, leading to slack, improper timing, and noisy operation. If not addressed, timing chain issues can cause:
• Engine noise (chain rattle)
• Poor idle and power delivery
• Timing inaccuracies affecting combustion
• Potential engine damage if timing is lost.
Replacing worn chains with an OE Match unit helps ensure accurate timing, preserves engine performance, and protects other internal engine components.
When to replace. Replace the timing chain when:
• There is rattling or slapping noise from the timing cover area
• Timing chain slack is detected in inspection
• You are performing an engine rebuild or overhaul
• Timing tensioner or guides show wear
• Irregular idle or misfires suggest timing drift
