Pipe Clamp 4/9 – Timing Chain Tensioner Feed Pipe Clamp 
Sold each - 2 requited per car

High-quality pipe clamp 4/9 designed for Porsche 911 and 964 turbo models, used to secure the solid hydraulic timing chain tensioner feed pipes.

This clamp plays a critical role in maintaining the correct routing and stability of the oil feed pipes supplying the hydraulic chain tensioners. Proper securing of these pipes is essential for reliable engine operation and long-term durability of the timing system.

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)
  • Porsche 964 (911) TURBO 3.3L 1991-93

Manufactured to OEM specifications, this clamp provides precise fitment, durability, and resistance to heat and oil exposure. Supplied individually, it is ideal for maintenance, repair, or engine restoration work.

Key Features

• Clamp size 4/9
• Suitable for Porsche 911 and Porsche 964
• Part number PCG51117402
• Designed for timing chain tensioner feed pipes
• Ensures secure pipe mounting and routing
• Resistant to heat, oil, and engine bay conditions
• Durable and corrosion-resistant construction
• OEM-style fit and performance
• Sold individually

Function and Purpose

This clamp is a vital component within the engine oil delivery system.

It helps to:
• Secure hydraulic timing chain tensioner feed pipes
• Maintain correct pipe routing and alignment
• Prevent vibration-related wear or fatigue
• Protect oil lines from movement and damage
• Ensure consistent oil supply to tensioners

Why Replace Pipe Clamps

Clamps can degrade over time due to heat and oil exposure.

Common issues include:
• Loss of clamping strength
• Corrosion or fatigue
• Pipe movement or misalignment
• Increased risk of oil line damage or leaks

Replacing worn clamps ensures secure installation and protects critical engine systems.

About Camshaft Lines

Engine Camshaft Oil Lines & Pipes – Precision Lubrication for Porsche Performance

The camshaft oil lines and pipes are vital components in your Porsche’s lubrication system, responsible for delivering pressurised oil from the engine block to the camshaft housings. This ensures constant lubrication of the cam lobes, lifters, and valve train components — preventing friction, overheating, and premature wear.

At Design911, we supply a premium range of camshaft oil lines and pipes designed to provide consistent oil flow and leak-free operation. Manufactured from high-grade stainless steel, reinforced rubber, or braided hose materials, these components are built to withstand the extreme heat and pressure of Porsche engines — ensuring reliability in both classic and high-performance models.

Whether you’re maintaining a vintage 911 or servicing a modern water-cooled flat-six, our replacements guarantee long-lasting durability, perfect fitment, and performance that meets or exceeds original engineering standards.

What Do Camshaft Oil Lines and Pipes Do?

These components play a crucial role in maintaining the correct oil pressure and distribution to the camshaft assemblies.

Core Functions:

  • Deliver pressurised oil to lubricate the camshafts, rocker arms, and valve train.
  • Maintain consistent oil flow under varying engine speeds and temperatures.
  • Reduce friction between moving components for smoother operation.
  • Prevent overheating and component scoring under high-performance driving conditions.

Proper lubrication through healthy oil lines ensures longer engine life, quieter operation, and improved efficiency.

Why Do Camshaft Oil Lines Fail?

Over time, camshaft oil lines are exposed to extreme conditions that lead to wear, blockage, or leaks — all of which can starve critical engine parts of oil.

Common Causes of Failure Include:

  • Heat degradation causing rubber lines to harden or crack.
  • Internal clogging from sludge or carbon deposits.
  • Corrosion of metal fittings and connectors.
  • Leaks at joints or crimps due to pressure fatigue.
  • Age-related wear, especially in classic or high-mileage engines.

Symptoms of failure include oil leaks around camshaft housings, ticking noises, low oil pressure warnings, or excessive valvetrain noise. Neglecting these signs can lead to serious engine damage.

Why Replace with Precision-Engineered Camshaft Oil Lines?

Replacing worn or damaged oil lines ensures proper lubrication, pressure stability, and longevity of the entire camshaft assembly. Our precision-fit, high-durability oil lines and pipes are designed to deliver consistent performance, improved sealing, and modern materials for longer service life.

Key Benefits:

  • Restores consistent oil pressure and flow to camshafts.
  • Prevents leaks and protects critical valvetrain components.
  • Improves reliability under high-performance conditions.
  • Crafted from corrosion-resistant, heat-stable materials.
  • Direct-fit compatibility for a wide range of Porsche models.
  • Ideal for engine rebuilds, restorations, and preventive maintenance.

Upgrading your camshaft oil lines ensures smooth operation, reduced friction, and maximum engine protection — essential for maintaining Porsche’s legendary performance.

Highlights:

  • High-quality Porsche camshaft oil lines and pipes.
  • Precision-engineered for consistent oil delivery.
  • Corrosion- and heat-resistant materials for long-term reliability.
  • Direct-fit installation for easy replacement.
  • Improves lubrication efficiency and engine performance.
  • Perfect for classic and modern Porsche engines alike.
