Information
Chain guide rail set.
This set is for total timing chain system renewal on Porsche 911/914/964 flat-six engines. It includes one brown-type guide rail (part number 91110522205) plus five black-type guide rails (part number 91110522207) - the exact quantities required for a complete timing-train overhaul. Each rail is manufactured to match Porsche’s original specification in material, geometry and wear profile.
SET OF 6, includes:
1 × Guide Rail Brown – part no. 91110522205
5 × Guide Rails Black – part no. 91110522207
Fits:
Porsche 911 1966 - 1989
Diagram ref no 2
• Function: Ensures proper timing-chain alignment, guides chain over sprockets and tensioners, controls chain path geometry, minimises vibration/noise and extends chain & sprocket life.
Over time, guide rails degrade through wear, cracking, distortion or mis-alignment. If any single guide rail is worn or old, you risk chain vibration or changing chain geometry - potentially causing chain noise, accelerated wear of sprockets, timing drift or even catastrophic failure. By replacing all six guide rails (1 brown + 5 black) as a coordinated set, you ensure:
• Uniform wear and material condition across the entire chain path
• Balanced chain ride, consistent tension and accurate timing
• Reduced noise, less chain slap or vibration
• Longer service life for chain, sprockets and tensioners
• Peace of mind during a major engine service or rebuild
When to replace:
• Chain noise or slap detected during start-up or under load
• Visual inspection shows grooves, wear tracks, deformation or cracked guides
• You are performing a full engine bottom end or top-end rebuild
• The engine has high mileage or you’re restoring to full specification

Oil lines may seem like minor components, but if they become defective, they can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, often functioning for years without issue. However, if a crack or break occurs, substantial amounts of oil can leak out—potentially draining the entire oil tank—and the affected component will no longer receive a reliable supply of engine oil.
To prevent such damage, it's recommended to replace aging oil hoses or lines before any issues arise. Full restorations generally involve replacing all oil lines to ensure reliability. Here, you can find high-quality replacement parts as described in the title.

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 guide rail, Black.
This guide rail maintains correct chain alignment, reduces wear on the timing chain and sprockets, and helps ensure accurate cam-shaft to crank-shaft timing over the life of the engine. Manufactured to match the original Porsche geometry, this rail provides direct-fit installation and restores proper chain path, quiet operation and long service life.
Sold each, 5 required per car.
Fits:
Porsche 911 1966 - 1989
Diagram ref no 2
• Position: Timing gearcase — the guide rail that supports/locates the front timing chain (or chains), depending on engine version.
• Function: Guides the timing chain to prevent excessive slack, misalignment or premature wear; supports longevity and accurate timing performance.
The timing chain guide rail is a critical component in the timing system of air-cooled Porsche engines: if the guide is worn, cracked, warped or missing, it can cause chain vibration, accelerated wear of the chain/sprockets, timing errors, noise or even catastrophic engine damage. Replacing it with a proper rail ensures correct chain path, quieter operation and long-term reliability.
When and why to replace:
• Timing chain slap or rattle is audible at startup or under load
• Visible wear on the existing guide rail (grooving, cracking, deformation)
• During engine rebuild or timing chain service when the covers are already open
• High-mileage or track-used engines where timing-system components have extended service life.

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.

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
