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.

Diagram Ref No 15
What This Product Does:
The oil line delivers oil at pressure to the timing chain tensioner assembly (or chain guide/tensioner unit) on the right-hand side of the engine, ensuring the timing chain remains properly tensioned and lubricated.
By maintaining correct oil flow, the tensioner can adjust chain slack, reduce vibration, ensure timing accuracy, and avoid premature wear.
Because of the high-stress environment (heat, vibration, chain loads), the line must be in good condition, correctly fitted, and leak-free to maintain timing system health.
Symptoms & Signs You May Need Replacement:
Oil leakage around the line, its fittings, or in the timing cover area, especially on the right-side chain housing. Since this is an oil line under pressure, any seepage or wetness is a warning.
Low oil pressure or warning light tied to the tensioner circuit; if the tensioner isn’t getting oil it may cause slack in the chain and abnormal noise.
Timing chain noise: rattling, clatter or slapping chains on the right side (chain tensioner unable to maintain correct tension because oil feed is blocked or leaking).
During engine rebuild or timing cover removal: If you’re servicing the timing system, and the oil line is original or worn, it’s wise to replace it while accessible.
Why Replacement Matters:
Crucial for timing chain health: The tensioner system’s performance relies on this oil feed line; failure can lead to chain stretch/jump, catastrophic timing issues or engine damage.
Maintains engine reliability: A faulty oil line might cause oil starvation or reduction in tensioner performance, which in a high-revving flat-six engine can lead to expensive damage.
Ease during service: During engine or timing chain work, replacing this line avoids returning later for failure. Since access requires removal of timing covers or partial engine disassembly, proactive replacement is cost-effective.

OEMatch Camshaft Lines — Fit, Function, Confidence
OEMatch supplies a curated selection of camshaft lines for Porsche models, chosen to support correct lubrication of the valve train and to suit restoration or routine service tasks. OEMatch camshaft lines components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types
- Stainless-steel rigid oil pipes with formed ends
- Braided high-temperature oil hoses with crimped fittings
- Rubber-reinforced feed lines for classic applications
Understanding OEMatch Camshaft Lines
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original camshaft lines.
OE (Original Equipment) refers to parts matching original specifications for the camshaft lines and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM camshaft lines engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Camshaft oil lines and pipes carry pressurised oil from the engine block to camshaft housings and valve-train bearings, maintaining flow to cam lobes and lifters, reducing friction and helping to control operating temperatures. Regular inspection supports early detection of leaks, blockages or corrosion.
Benefits Include
- Restores consistent oil pressure and flow to camshafts
- Improves sealing at joints to reduce leaks
- Uses corrosion- and heat-resistant materials for longer service life
Why Camshaft Lines Wear and Fail
- Heat degradation that hardens or cracks rubber sections
- Internal clogging from sludge, varnish or carbon deposits
- Corrosion of metal fittings, unions or clamps
- Pressure fatigue at crimps, joints or flex points leading to leaks
The Importance of Replacing with OEMatch Camshaft Lines
Replacing worn or damaged camshaft lines restores reliable oil delivery to the valve train, helps preserve camshaft and bearing life, and reduces the risk of consequential engine damage. During engine rebuilds, restoration or when symptoms such as oil leaks, ticking noises or low oil pressure appear, renewed lines are a prudent measure to protect internal components and maintain the serviceability of Porsche engines.
