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
