Timing Chain Guide & Tensioner Guide replacement set, consisting of:
2x 99610517353/1 - OE Match Timing Chain Guides
2x 99610517552/1 - OE Match Timing Chain Tensioner Guides
Manufactured to closely replicate the original Porsche components, this set provides a complete replacement for the timing chain guide and tensioner guide wear surfaces on compatible Porsche engines.
Fits:
Porsche 986 Boxster 2.5L / 2.7L / 3.2L 1997 - 2002
Porsche 996 3.4L 1998 - 2001
Diagram Ref No 33 & 30
The timing chain guide & tensioner guide set includes four precision-engineered plastic guides designed to match the original Porsche timing system components in fit, shape, and performance. When installed, these guides support the timing chain and help maintain correct chain tension and alignment throughout engine operation.
The timing chain guides and tensioner guides provide support and controlled routing for the timing chain, keeping it properly positioned as it rotates over the cam and crank sprockets. They work with the hydraulic tensioner to maintain correct chain tension, helping preserve accurate valve timing and reduce chain slack or noise.
Function:
• Timing Chain Guides (OE ref no 99610517353): Provide a wear-resistant surface that the timing chain runs against, supporting proper alignment and reducing chain vibration.
• Tensioner Guides (OE ref no 99610517552): Work in conjunction with the timing chain tensioner to keep chain tension stable, absorbing dynamic loads and preventing slack or chain chatter.
Together, the guides help ensure smooth, quiet chain operation, accurate timing, and long-term engine reliability.
Timing chain guides and tensioner guides are wear items in Porsche engines. Over time, original guide surfaces can wear, crack, or generate plastic debris due to heat and friction. Worn guides can lead to chain slack, noise, inaccurate valve timing, or accelerated chain and sprocket wear. Replacing them with OE Match components restores proper chain support, reduces operational noise, and helps protect expensive internal timing components.
When to replace:
• During timing chain service or overhaul
• If timing chain rattle / noise is detected at start-up or idle
• When engine has high mileage
• If prior guides show wear, cracking, or plastic debris
• As part of preventive maintenance on performance or daily-use engines

What These Products Do:
- The timing chain system in these Porsche engines synchronises the crankshaft with the intermediate shaft and camshafts — ensuring correct valve timing, ignition timing and overall engine sequence.
- The chains carry the drive from the crank to intermediate shaft. Guides/rails support and tension the chain, ensure correct path and reduce slack or noise.
- Over time, chains stretch, guides wear or break, tensioners may lose preload — which can result in timing slack, chain rattle, mis-timing or even catastrophic engine damage in worst-case.
- A full kit ensures you replace all critical components — chain, guides, rails — so that the timing system is restored to proper specification and you eliminate weak points.
Signs & Symptoms You Should Replace:
- A rattling or clattering noise from the front engine cover especially on start-up or at idle — often the chain has slack or the guide/rail is worn.
- Check engine light triggered by mis-timing, camshaft sensor errors or intermediate shaft errors.
- Loss of power, rough running or mis-firing — if timing has shifted due to chain stretch or guide failure, valve timing may be off.
- High mileage / age on the engine and you plan major service – pre-emptive replacement avoids risk of failure.
- Visual inspection (if cover removed) shows excessive chain slack, broken plastic guide rail, broken tensioner, or damaged rail.
- During engine work (removal of front engine cover, timing cover, etc) – if the drive system is exposed you should replace the chain kit rather than just individual items.
Why Replacement Matters:
- Protects engine integrity — on these engines especially, a failed timing chain system can result in valve/piston contact or catastrophic failure.
- Restores correct timing — ensuring the timing chain, guides and rails are all new means valve timing and ignition timing will be accurate and reliable.
- Eliminates noise & improves reliability — replacing worn components removes chain slap noise and reduces risk of future damage.
- Cost-effective preventive maintenance — since the timing system requires major disassembly, doing the full kit while you’re already in there pays off rather than having to open the engine again later.

This timing chain kit includes the timing chains for the
camshaft and intermediate shaft, as well as the slide and tension rails.
Due to the complex design with an intermediate shaft and two
overhead camshafts, the water boxers of the modern Porsche 911 Carrera and
Boxster have a variety of chains and slide rails. These vary depending on the
displacement or model year, even within a series.
The chain guides were slightly changed between the 3.4L and
3.6L Carrera engines from 2001 to 2002. The engines of the 911 turbo and GT
models, however, are based on the proven 911 technology from the previous
models. The timing chains as well as slide rails and tensioning rails for the
valve control are fundamentally different.

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.
Signs of Timing Chain Kit Failure
Noise: A failing timing chain often produces a rattling or slapping noise, particularly noticeable at startup, idle, or during acceleration.
Reduced Performance: Stretched or worn chains can disrupt engine timing, resulting in sluggish acceleration, reduced power, or poor overall performance.

Common issues or symptoms:
Rough idle / misfires: Faulty actuator disrupts precise valve timing, leading to uneven idling or misfires.
Reduced engine performance: Loss of power or hesitation at certain RPMs can be linked to improper camshaft adjustment Check Engine Light (CEL), often triggered when the engine control unit (ECU) detects misalignment or malfunction in camshaft timing - very common with actuator failure.
Faulty actuator disrupts precise valve timing, leading to uneven idling or misfires Diagnostic Trouble Codes (DTCs): Codes like P0010, P0011, P0012, P0013, P0014 often point to camshaft actuator or timing issues. They indicate conditions such as stuck timing advance/retard, or electrical faults in the actuator circuit Failure Causes: Oil contamination or sludge can clog the actuator, impairing function. Electrical problems such as wiring degradation or poor connector contact can impede correct activation
Diagnostic & repair advice check oil quality and change intervals - fresh, clean oil helps prevent buildup that hampers actuator performance scan for and interpret fault codes using an OBD-II scanner to pinpoint actuator failure or control circuit issues Inspect connectors and wiring for corrosion or looseness Replace defective solenoid(s) with OEM or high-quality equivalents if internal stick or mechanical failure is suspected.

The timing chain transfers rotational movement through the engine’s timing system so the camshafts open and close the intake and exhaust valves at the correct moment in the combustion cycle. Accurate synchronization between the crankshaft and camshafts is essential for optimal engine performance, efficiency and reliability.
Replacing worn or stretched timing chains helps maintain correct valve timing and prevents potential engine damage caused by timing inaccuracies.
Function
• Engine Timing Synchronisation: Links the intermediate shaft and camshafts
• Valve Control: Ensures intake and exhaust valves operate at precise timing intervals
• Durability: Designed to withstand continuous high-speed engine operation
• Direct Replacement: OE Match construction ensures correct fit and performance
Timing chains operate continuously under high load and temperature inside the engine. Over time they may stretch or wear, which can lead to inaccurate valve timing, engine noise, or performance loss. Installing a new OE Match timing chain helps maintain precise engine timing, ensures smooth operation of the valve train and protects critical engine components from premature wear.
Consider replacing the timing chain when:
• Performing a major engine rebuild
• Servicing the timing system or chain tensioners
• Experiencing timing chain noise or rattle

Function
• Maintains correct timing chain tension during engine operation
• Prevents chain slack and misalignment
• Ensures accurate camshaft timing and engine performance
• Reduces engine noise, particularly during cold starts
• Protects against timing chain slip or jump, which can cause severe engine damage
A worn or failing chain adjuster can allow slack in the timing chain, leading to incorrect valve timing and potential engine damage. In severe cases, the chain can skip teeth, resulting in catastrophic internal failure. Replacing the adjuster ensures proper chain control, protects engine components, and restores smooth, quiet operation.
When to replace
• Rattling or chain noise on cold start
• Engine timing issues or misfire symptoms
• During timing chain or engine rebuild
• High mileage engines with original tensioners
• Evidence of oil leakage or reduced hydraulic pressure

- Engine light triggered due to timing issues.
- Engine misfires or rough running caused by timing irregularities.
- Excessive timing chain wear or visible slack.
- In severe cases, loss of timing leading to serious engine damage.
The chain tensioner adjuster is a critical timing component. If it fails, the timing chain can skip teeth or lose tension, resulting in poor engine performance or catastrophic internal damage.
This part is especially important during engine rebuilds, timing chain services, or if unusual noises develop from the timing system.

Information
Guide rail - Cylinder 1-3.
The timing chain tensioner is designed to maintain correct chain tension in Porsche M96 and M97 engines. This hydraulic tensioner ensures the timing chain remains tight, properly aligned, and stable across all engine speeds, preventing chain slack, noise, and timing deviation.
Fits:
Porsche 986 Boxster 2.7L / 3.2L 2003 - 2004
with Engine codes: M96.23 / M96.24
Porsche 987 Boxster 2.7L / 3.2L / 3.4L 2005 - 2008
with Engine codes M96.25 / M96.26 / M97.20 / M97.21 / M97.22

Porsche 997.1 3.6L /3.8L 2005 - 2008
with Engine codes M96.05 / M97.01
Diagram Ref No 33.
Built to original Porsche specifications, the tensioner uses controlled oil pressure to absorb chain vibration and compensate for thermal expansion, ensuring precise valve timing and smooth engine operation.
Over time, the timing chain tensioner can weaken internally, allowing the chain to develop slack and produce rattling noises, especially on start-up. A failing tensioner can cause timing drift, poor running, and accelerated wear of the guides and sprockets. If left unresolved, the chain may even skip a tooth, risking serious internal engine damage. Replacing the tensioner restores stable chain control, accurate timing, and long-term engine protection.
When to replace:
• You hear chain rattle, especially during cold start
• Fault codes or symptoms indicate timing deviation
• Engine runs rough, lacks power, or shows intermittent misfires
• Visible wear or oil leakage around the tensioner housing
• Chain guides have been replaced during an engine service
• Preventatively during M96/M97 engine rebuilds or high-mileage maintenance

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.

Benefits Include
- Restores accurate valve timing and smoother running
- Reduces start-up rattle and in-service chain noise
- Limits the risk of valve-to-piston contact from excessive chain slack
- Chain stretch or elongation from long service life
- Worn or leaking hydraulic tensioners losing damping or pressure
- Abrasion or breakage of guides due to heat and contamination
- Oil degradation or low oil pressure accelerating component wear
The Importance of Replacing with OEMatch Chains & Tensioners
Timely replacement protects the engine from progressive damage and helps preserve performance and drivability. Using correctly specified chains, guides and tensioners reduces the chance of unexpected failure during operation and supports consistent timing across the rev range. OEMatch provides a wide selection of Porsche components, cataloguing over 4,000 part numbers and more than 8,700 OE cross-references to assist repairs across different model generations.
Advantages
- Parts matched to Porsche timing-system specifications where applicable
- Options for hydraulic and mechanical tensioning arrangements
- Complete kits simplify overhaul work by including guides, seals and fixings
