• Coolant leaks Engine overheating
• Sudden loss of coolant pressure
• Potential engine damage.

Replacing worn hoses with a Genuine Porsche unit ensures proper sealing, correct routing and dependable cooling system function.

Typical reasons to replace:
• Visible cracking, bulging or soft spots
• Coolant smell or residue around hose ends
• Overheating issues or fluctuating temperatures
• During cooling system service (pumps, thermostats, radiators)
• Preventative maintenance on older 987 models.

Diagram Ref No 5

What This Product Does:

• The guide/slide rail helps maintain correct path and tension for the timing chain, preventing the chain from flopping, jumping, or hitting other components.

Symptoms Of Failure:

• Rattling or clattering noise from the timing chain cover area (especially at cold start or idle) because the chain may be loose and hitting the guide/rail or adjacent parts.
  
• Poor engine performance: misfires, rough idle, hesitation on acceleration. This is because incorrect timing = valves and pistons not synchronised.
  
• Check Engine Light: with timing or cam/crank correlation codes. If the chain jumps or the guide fails significantly, the timing can get out of spec, triggering the ECU. 
  
• Metal shavings in oil or oil pan (in more advanced wear). If the chain or guide breaks up, fragments can circulate.
  
• Engine won’t start or sudden failure in worst-case: if timing chain jumps many teeth or breaks, the engine may stop or suffer internal damage.
  
  

Why Replacement Matters:

• Because the timing chain and its guides are critical for engine timing: if the guide rail fails and allows the chain to slip, the engine’s valve timing will go off. This can lead to serious internal engine damage (valves hitting pistons, heavy wear) in many high-performance engines.
  
• Replacing the guide rail (and possibly the chain, tensioners, etc) before catastrophic failure helps avoid a full engine rebuild or replacement, which is far more expensive.
  
• Even though the part itself may not be extremely expensive (the guide rail), the labour cost of access is high (because to reach it you may need to remove covers, maybe ancillary components) — doing it early is more cost-effective.
• Ensures the engine continues to operate as designed, maintaining performance, reliability and longevity.

A leaking gasket can lead to poor engine running, reduced boost, increased emissions or even turbocharger strain. Replacing it with the genuine product ensures factory-correct sealing, protects your engine’s performance potential and helps preserve value.

When to replace:
• Intake manifold removed for service or repair.
• Signs of induction leakage: unstable idle, boost pressure dropped, check engine faults.
• Age-related wear, material fatigue or previously reuse of the old gasket.
• Planning long-term reliability or restoring to original specification.

What This Product Does:

• The timing chain synchronises the crankshaft with other components — here especially linking to the oil pump / cam drive path — so that the engine’s valves operate at the correct times relative to piston movement.
• Over time, chains can stretch, guides may wear, tensioners may degrade — all of which will allow slack in the drive, noise, timing drift or even failure.
• Essentially, this chain is a critical link in the engine’s timing system — it must stay within spec to ensure the engine runs as designed.

When You Should Consider Replacement:

• Rattling or clattering noise from the engine’s timing‐cover area, especially on cold start, idle or at low revs. Slack chain often causes this.
  
• Timing-related fault codes — cam/ crank correlation errors, or variable valve timing issues that could stem from chain/tensioning irregularity.
  
• Loss of engine performance, rough running, mis-fires, or inconsistent response — because timing drift can affect the engine’s breathing and ignition.
  
• High mileage or long service interval without chain replacement — wear accumulates even if symptoms are subtle.
  
• Visual inspection (where possible) may show wear or elongation in chain links, damaged guides or tensioner issues.

Why Replacement Matters:

• Engine protection: A failed or excessively worn timing chain can cause piston-valve contact, or major internal engine damage. Replacing the chain significantly reduces that risk.
  
• Maintains timing accuracy: A new chain ensures correct timing events — vital for power delivery, engine smoothness, efficiency and longevity.
  
• Noise & NVH improvement: Slack or worn chain components often produce unwanted noise and degrade refinement — renewed parts improve comfort.
  
• Cost-efficiency: Since accessing the chain involves significant labour (front engine cover, oil pump, possibly other removal), replacing the chain while you’re already in saves repeated work.

•  Applications: Required when the original drive shaft shows wear, CV joint failure (clicking on turns), shaft play, torn boots, vibration under drive, or during rear axle/differential servicing to restore factory-standard drive feel and reliability.

The drive shaft (CV-axle) is an essential component of your vehicle’s drivetrain, especially in rear- or all-wheel-drive vehicles like the Panamera. A failing shaft or CV joint can lead to a range of issues:  
• Clicking or popping noise during turning due to worn CV joints
• Excessive vibration, especially under acceleration or at speed
• Loose play in the axle, causing imprecise handling or driveline lash
• Torn boots leading to grease loss, contamination and joint failure

Replacing it with the correct genuine Porsche part ensures the drive system retains proper torque transfer, smooth operation, correct alignment and long-term durability.

When and why to replace:
• Hearing clicking or clunking during sharp turns or acceleration
• Detecting vibration or shudder under load or at speed
• Noticing torn boots, leaking grease or visible playful movement in the shaft assembly
• During rear differential, half-shaft or bearing service where access is available
• On high-mileage vehicles where original components may be fatigued or worn

Diagram Ref No 1

What This Product Does:

• The timing chain synchronises the crankshaft’s rotation with the camshaft(s), ensuring valves open and close at the correct times in relation to piston movement. Without correct timing the engine cannot run properly.
• Over time, because the chain is under constant load, it may stretch or wear, tensioners can degrade, guides may wear out. When this happens, slack can appear in the drive which compromises timing, performance, noise, and in worst case leads to engine damage.
  
• This chain is the core drive chain for a given Porsche engine — making it a critical component of engine operation.

When You Should Consider Replacement:

• Noise from the timing cover area (rattling or clattering, especially at cold start or idle) — a sign of slack chain or failing guides.
  
• Engine performance issues: If you experience misfires, power loss, or the engine is not running smoothly, timing chain wear could be a cause.
  
• Diagnostic codes indicating camshaft timing deviation or chain position errors — the chain may have stretched or the drive system may have issues.
  
• High mileage / old age / major service: If the vehicle has substantial miles, or if you are performing major engine service (timing cover off, chain exposed), it’s prudent to install a new chain rather than rely on a worn one.
  
• Visual inspection (if accessible) showing chain wear, guide rail wear or tensioner issues.
  
• If the chain breaks (rare) the engine will not run; therefore proactive replacement pays in reliability.
  
  

Why Replacement Matters:

• Engine integrity and longevity: A failed timing chain can lead to catastrophic engine damage (valves colliding with pistons, etc). Replacing the chain reduces that risk.
  
• Performance & timing accuracy: A new chain ensures timing is correct and optimised — improving engine smoothness, power delivery and reliability.
  
• Noise & NVH improvement: Replacing a worn chain can remove unwanted noise (slap, rattle) from the engine front.
  
• Cost-efficient preventive maintenance: Since accessing the timing chain involves high labour (engine front cover, etc), replacing the chain while you are already in has a better return on investment than waiting for failure.

What This Product Does:

• In a timing‐chain drive system (crankshaft → intermediate shaft → camshafts), there are guides/rails that the chain runs on. These guides keep the chain aligned, reduce vibration or deflection, and support tensioners in maintaining correct chain tension.
• The slide rail is one of these guiding components — it provides a smooth surface and correct route for the chain, and helps ensure the chain remains properly engaged with sprockets and tensioners.
• If the slide rail is worn, cracked or damaged, the chain may run with slack, contact adjacent components, produce noise, or even skip/skip-tooth under stress — which affects timing and can lead to engine damage.

When You Should Consider Replacement:

• You are already servicing the timing chain system (timing cover off, chain/guide/tensioner replacement) — since access is already required, replacing the guide rail is cost‐effective and prevents future access.
• You hear rattling or a clattering noise from the front of the engine (timing cover area) on cold start or idle, which can indicate chain deflection or guide wear.
  
• You have diagnostic codes relating to camshaft or intermediate shaft timing variations — a damaged or worn guide can cause chain timing to vary.
• Visual inspection (if cover removed) shows the guide rail is cracked, has excessive wear, gouges, or the chain has worn a groove in the rail.
• The vehicle has high mileage and the engine is performance-oriented — these guides can be wearing items and proactively replacing them improves long-term reliability.

Why Replacement Matters:

• Maintain timing accuracy & reliability: If the chain runs on a compromised guide, chain slack or mis-tracking can occur — which leads to timing drift, loss of power, or in worst cases, engine damage.
  
• Eliminate noise and improve smoothness: Worn guides allow chain slap, noise during engine operation, or rougher operation — replacing the slide rail restores proper chain path and quietness.
  
• Prevent escalated failure: A damaged guide could allow the chain to skip or jump, which on high-performance Porsche engines can mean valve-to-piston interaction and major damage.
  
• Efficient service: Since replacing a guide rail often requires similar labour as chain/tensioner replacement, doing it while the engine is opened saves future labour and increases reliability.
