Camshaft To Chain Tensioner Oil Feed Line Extension. Porsche 911

Camshaft To Chain Tensioner Oil Feed Line Extension.
Restore the precise oil supply path for your Porsche 911’s timing chain assembly with this feed line extension. Designed for left-side feed from camshaft to chain tensioner in 911 models (1978-83 3.0 L/SC and 1984-89 3.2 L), this oil line ensures correct oil delivery, tensioner performance and timing stability.

Fits:

• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50
• Porsche 911 1978-1989 3.3L Turbo (930)

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.
