Diagram Ref No 9
What This Product Does:
- This oil line extension carries high-pressure oil from the camshaft feed (or appropriate oil gallery) to the timing chain tensioner mechanism. The tensioner ensures correct chain slack and timing of the engine’s valve train.
- Because the timing chain system is under constant stress (heat, RPM, vibration), the feed line must maintain integrity, correct diameter, correct routing, correct fittings and leak-free operation to protect the chain drive system.
Symptoms & Signs It May Need Replacement:
- Oil leakage around the chain-cover region, especially on the driver’s side near the timing chain housing or tensioner.
- Excess chain noise or slapping from the timing chain area — a failing feed line could reduce tensioner performance, allowing slack.
- Low oil pressure or warning associated with engine timing assembly (though this is less direct).
- During engine rebuild or timing chain service: if the original line is old, has suffered heat damage, is bent, kinked, or the wrong specification, replacement is highly recommended.
Why Replacement Matters:
- Protects critical components: The timing chain and tensioner are essential for proper valve timing; a failure here can lead to engine damage. A compromised oil feed line undermines that.
- Cost-effective preventative maintenance: Since access to the timing chain housing is complex (engine removal or major cover removal), replacing this feed line while you’re already working on the engine is much cheaper than later diagnosing a failure.

Manufactured to OE specifications, this replacement cam line offers precise fitment, durability and dependable oil delivery under demanding engine operating conditions. It is an essential component for maintaining the effectiveness of the upgraded chain tensioner system commonly fitted to classic Porsche 911 models.
What This Product Does:
- Supplies pressurised engine oil to the left-hand hydraulic chain tensioner.
- Maintains correct timing chain tension throughout the engine's operating range.
- Supports accurate valve timing and engine efficiency.
- Helps reduce timing chain vibration and movement.
- Forms part of the upgraded pressure-fed chain tensioner system.
- Contributes to the long-term reliability of the engine timing assembly.
Symptoms Of Wear Or Failure:
- Oil leaks around the left-hand cam housing or timing chain cover.
- Oil seepage from unions, fittings or pipe connections.
- Corrosion, cracking or physical damage to the oil line.
- Reduced oil flow to the hydraulic chain tensioner.
- Timing chain rattle, particularly during start-up.
- Increased engine mechanical noise.
- Oil contamination around surrounding engine components.
- Premature wear of timing chain tensioner components.
Why Replacement Matters:
- The left-hand cam line operates in a high-temperature, high-vibration environment and is subjected to constant oil pressure. Over time, ageing, corrosion and fatigue can weaken the line or its fittings, resulting in oil leaks or restricted oil flow.
- A failing cam line can reduce the effectiveness of the hydraulic chain tensioner, potentially allowing excessive timing chain movement and accelerated wear of critical engine components. In severe cases, inadequate tensioner operation may affect engine timing accuracy and reliability.
- Replacing a worn or damaged left-hand cam line helps maintain proper oil delivery to the chain tensioner system, reduces the risk of oil leaks and supports reliable engine timing performance. An OE Match replacement restores the integrity of the lubrication circuit and helps protect valuable Porsche engine components from unnecessary wear.
