Information
Chain tensioner.
The timing chain tensioner applies consistent pressure to the timing chain, preventing it from developing slack or vibration as the engine runs. By keeping the chain tight, it helps maintain precise valve timing, which is essential for smooth combustion, engine efficiency, and long-term reliability.

• Application: Timing chain tensioner - typically one per side of the engine (left and right) depending on the model and engine variant.
• Function: Maintains proper timing chain tension
• Benefits: Improves timing accuracy, reduces engine noise, prevents premature wear
Installed in the timing cover area, the tensioner operates off oil pressure and spring force to automatically adjust the chain’s tautness as engine speed and temperature vary. This prevents noise such as chain slap, reduces premature wear on timing components, and helps avoid timing misalignment - which, if left unchecked, can lead to poor engine performance or damage.
A properly functioning timing chain tensioner is essential for engine health and performance. When a tensioner weakens or fails:
• The timing chain can slacken or skip, leading to noisy operation and accelerated wear.
• Valve timing accuracy deteriorates, which can reduce power and fuel efficiency.
• In severe cases, timing chain misalignment can lead to internal engine damage.
Replacing a worn tensioner ensures that the timing system maintains correct chain tension - promoting smoother operation, better combustion control, and improved engine longevity.
Replace the timing chain tensioner if you notice:
• Rattling or clattering noises from the timing chain area
• Reduced engine performance or rough idle
• Timing codes or check engine light related to valve timing
• During engine rebuilds, timing chain replacement, or if the original tensioner shows signs of wear

Engine timing Chain Kit for camshaft and oil pump .
Complete replacement timing chain set. It includes the main drive chain, oil-pump drive chain, sprockets/gears, chain guides, and tensioner components needed to synchronise the crankshaft and camshafts - ensuring precise valve timing and pump operations.
Fits:
Porsche 970 3.0L Panamera
Porsche 958 3.6L Cayenne

• Complete kit: Includes all critical parts (chain, sprockets, guides, tensioner) for a correct and reliable rebuild.
• Use Cases: Timing chain replacement, engine rebuild, preventive maintenance, repair after chain noise or wear, restoration of engine timing integrity.
Manufactured to match the original specifications in terms of chain length, strength, link design, and guide/tensioner geometry, this kit provides a direct-fit replacement for worn original components. Installation restores the engine’s timing integrity - crucial for proper combustion, timing accuracy, and long-term reliability.
Over time and under high-mileage, original timing chains can stretch, wear or develop slack, while guides or tensioners may wear down - leading to imprecise valve timing. This can result in poor combustion, loss of power, rough running, or - in worst cases - valve-to-piston interference and severe engine damage. Using a fresh timing chain kit restores original timing accuracy, ensures oil pump and valve timing integrity, and maintains long-term engine reliability.
When to replace:
• If the engine shows timing chain noise (rattling, knocking), especially on cold start or under load.
• During high-mileage maintenance or engine overhaul to prevent future chain stretch and failure.
• If you notice timing-related faults: misfires, poor idle, check-engine light, or performance loss.
• When doing cylinder head or oil-pump work - fitting a new chain kit as part of a comprehensive rebuild.
• As a preventive upgrade for older engines to safeguard against catastrophic timing failure.
