    Required Quantity

Three upper gasket sets are specified for the fuel collection pipe and high-pressure injector assembly

What Is This Part?

This gasket set services the upper sealing position of the high-pressure fuel injector. It belongs to the fuel collection pipe and injector assembly, where the injector connects to its fuel supply. The sealing components form part of that connection rather than the injector's electrical control or fuel-metering mechanism. It is intended for sealing repairs and injector refitting work, with the exact replacement procedure determined by the engine application.

What Does This Part Do?

  • Seals the upper connection: Provides the sealing components used at the upper injector position.
  • Supports injector resealing: Allows the upper sealing components to be renewed when servicing the injector assembly.
  • Works with the fuel collection pipe: Forms part of the sealing arrangement between the fuel supply assembly and injector.

    Why Replace This Part?

Renew the upper sealing components if inspection confirms damage, deterioration or leakage at their connection. A seal that is cut, distorted or no longer seats correctly should not be relied upon during reassembly. Inspect the adjoining injector and connection as well, because damaged mating surfaces or an incorrectly seated injector may also need attention.

Injector removal is another important repair context. High-pressure injector servicing requires renewal of the sealing and service components specified by the applicable repair instructions, even when the injector itself is being reused. Follow the engine-specific procedure rather than assuming the removed seals can be refitted. 

When to Replace This Part?

  • Visible seal damage: Cuts, splits, distortion or deterioration found during dismantling.
  • Confirmed connection leakage: Fuel dampness or a fuel smell traced to the upper injector sealing position.
  • Poor seating: A displaced or damaged seal that prevents correct assembly.
  • Injector servicing: When the applicable removal and refitting instructions specify new upper sealing components. 
  • Persistent running symptoms: Rough idle, misfires or hard starting warrant diagnosis; they do not by themselves confirm that this gasket set needs replacement.

    Where Is This Part Fitted?

Location: At the upper high-pressure injector position within the engine's fuel collection pipe and injector assembly.

FAQs

  • Will new seals repair a faulty injector? They address the sealing connection. Injector clogging, electrical faults or internal leakage require separate diagnosis.
  • Can the old seals be reused after injector removal? Follow the engine-specific repair instructions. High-pressure injector service guidance calls for replacement of the specified sealing and service components when an injector is removed and reused. 
  • What should be checked before fitting? Check the injector seating area and mating connection, and keep dirt out of the assembly during installation. 
  • Are special fitting procedures important? Yes. Use the applicable repair instructions and appropriate tools; high-pressure injector seals can require different handling depending on their position and design. 

    Product Summary
  • Product: Upper fuel injector gasket set.
  • Brand: OE Match.
  • Purpose: Renews the upper injector sealing components.
  • Fitted position: Upper high-pressure injector connection in the fuel collection pipe assembly.

About Timing covers and gaskets

Timing Covers & Gaskets – Protect Your Porsche’s Engine Timing System

The timing cover and its gasket play a crucial role in your Porsche’s engine reliability. These components seal the timing system — protecting the timing chain, gears, and belt from oil leaks, debris, and contaminants. A secure timing cover ensures proper lubrication, maintains internal oil pressure, and prevents costly engine damage caused by fluid loss or contamination.

At Design911, we supply a wide range of timing covers and gaskets suitable for Porsche models old and new. Manufactured using high-grade aluminium, composite materials, and heat-resistant rubber compounds, our products are designed to withstand vibration, temperature extremes, and oil exposure while providing a perfect, leak-free fit.

Whether you’re maintaining a classic air-cooled 911 or rebuilding a high-performance GT engine, our timing covers and gasket sets deliver exceptional durability, sealing performance, and reliability.

What Do Timing Covers & Gaskets Do?

The timing cover shields the engine’s timing components and works in tandem with its gasket to maintain a clean, sealed environment.

Core Functions:

  • Protect the timing chain and gears from dirt, debris, and oil contamination.
  • Prevent oil leaks by sealing the timing section from external elements.
  • Maintain proper oil pressure in the engine.
  • Assist in heat dissipation around the timing assembly.
  • Ensure long-term reliability of moving components like the camshaft and crankshaft.

A properly sealed timing cover is essential for consistent performance and preventing internal wear caused by oil leaks or debris infiltration.

Why Do Timing Covers & Gaskets Fail?

Due to constant exposure to oil, heat, and vibration, timing covers and gaskets can degrade or crack over time — leading to oil leaks and reduced performance.

Common Causes of Failure Include:

  • Gasket hardening or shrinkage from prolonged heat exposure.
  • Cracked or warped covers from over-tightening or impact.
  • Oil leaks caused by poor sealing or material fatigue.
  • Contaminant build-up inside the timing housing.
  • Improper gasket installation or uneven torque during servicing.

Symptoms of failure include visible oil leaks at the front of the engine, oil dripping under the timing chain cover, or low oil levels. Ignoring these issues can lead to costly timing component wear or engine failure.

Why Replace Components?

Replacing worn or leaking timing covers and gaskets ensures your Porsche’s timing system remains protected and properly lubricated. Our high-performance replacement parts are designed for exact fitment, durability, and long-term sealing efficiency.

Key Benefits:

  • Prevents oil leaks and pressure loss.
  • Protects critical timing components.
  • Enhances reliability under high-performance driving.
  • Manufactured from durable, heat-resistant materials.
  • Direct-fit compatibility with Porsche 911, Cayman, Boxster, and more.
  • Ideal for rebuilds, restorations, or preventive maintenance.

A fresh timing cover and gasket set is vital for maintaining your Porsche’s precision engineering and preventing oil contamination or mechanical failure.

Highlights:

  • Precision-engineered timing covers and gaskets for Porsche engines.
  • Protects timing chain, gears, and seals against leaks and debris.
  • Built from heat-resistant aluminium and reinforced rubber.
  • Perfect fit for Porsche performance and classic models.
  • Durable, leak-free sealing for long-term reliability.
  • Essential for rebuilds, restorations, or service maintenance.
