Camshaft To Tensioner Oil Line, Right. Porsche 911 / 964

Camshaft To Tensioner Oil Line, Right.
Ensure proper oil supply to your timing chain tensioner with this oil line for the right-hand side. Designed for Porsche 911 models (1978-89) and Porsche 964 Turbo 3.3L (1991-93), this line delivers pressurised oil from the camshaft feed to the chain tensioner unit, maintaining correct chain tension and timing accuracy.

Fits:

• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 964 (911) TURBO 3.3L 1991-93

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.
