Rear silencer exhaust gasket by OE Match for Porsche 930 Turbo and 965 Turbo applications. This replacement seals the exhaust connection during joint repairs or reassembly.

Fits

• Porsche 930 Turbo 1977-89
• Porsche 965 Turbo 1989-94
  
  

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The gasket forms a seal where adjoining exhaust components meet. Its purpose is to contain exhaust gases at the connection rather than allowing them to escape around the joint. OE Match develops replacement components around Porsche applications, using original references and application details when assessing suitability.

Functions

• Seals the exhaust connection.
• Helps contain gases within the exhaust assembly.
• Supports joint resealing after dismantling.
  
  

Technical Details

• Part reference: 93012319105.
• Intended application: rear silencer exhaust connection.
  
  

Symptoms of Fault

• A ticking or blowing sound near the connection.
• Dark soot deposits around the sealing faces.
• An exhaust odour associated with a leaking joint.
  
  

Why Replacement Matters

Repeated heating and cooling can leave an old gasket hardened or compressed, making it unsuitable for resealing after removal. Renewing the gasket when the connection is opened helps address joint leakage. Inspect flange condition, component alignment and fastening hardware at the same time; a replacement gasket alone will not correct damaged mating faces or uneven clamping.

FAQs

Is the removed gasket suitable for refitting?
Renewal is generally preferable because a previously compressed gasket may not seal again.

Should sealant be applied?
Use the installation instructions applicable to the vehicle and component; do not assume additional sealant is required.

What should be checked if leakage returns?
Examine flange distortion, exhaust alignment and fasteners that may not distribute clamping force evenly.

Screw Plug M10 X 1.

The Genuine Porsche Screw Plug M10 × 1 (Part Number: 9001240230A) is an original equipment threaded sealing component used within the turbocharger oil supply system of selected Porsche 964 Turbo models.

Fits:

• Porsche 964 (911) TURBO 3.3L 1991-93
• Porsche 964 (911) TURBO 3.6L 1991-93  

Diagram Ref No 15

Designed with an M10 × 1 metric thread, this screw plug closes a specified threaded opening within the turbocharger oil supply arrangement, helping maintain the integrity of the associated oil system.

The turbocharged Porsche flat-six engine relies on a controlled supply of engine oil to lubricate the turbocharger's internal shaft and bearing assembly. Correct oil supply and sealing are essential because the turbocharger operates at extremely high rotational speeds and elevated temperatures.

The screw plug forms part of the original turbocharger oil system assembly and is positioned alongside the associated oil pipes, banjo bolt and sealing components in Porsche's parts catalogue.

When correctly installed, the plug helps prevent oil escaping through its designated threaded opening, supporting the intended oil system configuration.

Manufactured to Porsche's original equipment specification, the component provides the correct thread size and fitment for the applicable installation.

During operation, the plug is exposed to engine vibration, heat and the operating conditions of the surrounding oil system.

Although designed for long service life, it may become damaged through corrosion, overtightening, incorrect installation, damaged threads or repeated removal during maintenance.

A damaged screw plug or compromised sealing interface may result in oil leakage around the associated connection.

If an oil leak develops near the turbocharger, escaping oil may contaminate surrounding engine components and potentially contact hot exhaust surfaces.

Replacing a worn or damaged screw plug with a Genuine Porsche component helps restore the specified threaded closure, maintain oil system integrity and support reliable turbocharger operation.

What This Product Does:
The screw plug is a threaded closure component fitted at a designated location within the turbocharger oil supply assembly.

Its primary function is to seal the corresponding threaded opening and prevent unwanted oil leakage.

The turbocharger oil supply system delivers engine oil to the turbocharger's internal bearing arrangement.

The associated pipework and connections must remain correctly sealed to maintain the intended oil circuit.

The screw plug closes its specified opening without providing an external hose or pipe connection.

Its main functions include:

• Sealing a threaded opening: Closes the designated M10 × 1 threaded port.
• Preventing oil leakage: Helps stop oil escaping through the closed connection.
• Maintaining oil system integrity: Supports the original turbocharger oil supply arrangement.
• Providing secure mechanical closure: Maintains the required threaded fastening.
• Supporting turbocharger lubrication: Helps preserve the integrity of the oil supply system serving the turbocharger.
• Maintaining factory configuration: Restores the specified original Porsche closure component.
• Supporting engine maintenance: Allows a damaged plug to be replaced during turbocharger oil system repairs.
• Providing correct thread compatibility: Matches the M10 × 1 threaded specification.
• Supporting reliable sealing: Works with the specified sealing arrangement at its installation location.
• Helping prevent oil contamination: Reduces the possibility of oil escaping onto adjacent components.

Symptoms Of Wear Or Failure:
Screw plugs are generally durable components without moving parts. However, mechanical damage, incorrect installation or deterioration of their sealing surfaces can compromise their operation.

Common signs of a damaged or defective screw plug include:

• Visible oil leakage: Engine oil may escape around the threaded connection.
• Oil residue near the plug: Damp or oily deposits may develop around the fitting.
• Oil drips: A significant leak may allow oil to collect beneath the affected engine area.
• Burning oil smell: Escaping oil may produce an odour if it reaches hot components.
• Smoke from oil contamination: Oil contacting hot exhaust surfaces may generate smoke.
• Damaged threads: Stripped or distorted threads may prevent secure installation.
• Cross-threading: Incorrect installation may damage the plug and its receiving threads.
• Loose plug: Incorrect tightening or damaged threads may compromise fastening.
• Corroded plug surface: Deterioration may affect the component's condition.
• Damaged sealing face: Scratches, pitting or distortion may prevent proper sealing.
• Rounded tool engagement: Previous servicing damage may make removal or tightening difficult.
• Cracked plug: Excessive mechanical stress may cause physical failure.
• Incorrect replacement plug: A component with an unsuitable thread pitch or length may not seat correctly.
• Persistent leakage after servicing: Incorrect installation or a damaged sealing interface may leave the connection leaking.
• Visible damage to the receiving port: The surrounding threaded opening may be damaged even when the plug appears serviceable.

Why Replacement Matters:
Replacing a defective screw plug helps maintain a secure, properly sealed connection within the turbocharger oil supply assembly.

A damaged plug may allow oil to escape, leading to contamination of surrounding components and potentially reducing the reliability of the oil system.

An oil leak near hot turbocharger or exhaust components also presents an important maintenance concern.

If the plug's threads are damaged, continued tightening or reuse may worsen damage to the receiving component.

Installing a Genuine Porsche replacement Screw Plug helps to:

• Restore the threaded seal: Replace a defective closure component.
• Prevent unwanted oil leakage: Address leakage caused by a confirmed damaged plug.
• Maintain oil system integrity: Support the original turbocharger oil supply assembly.
• Restore secure fitment: Replace a plug with damaged or stripped threads.
• Reduce oil contamination: Help prevent oil escaping onto neighbouring engine components.
• Support turbocharger servicing: Provide replacement hardware during oil system maintenance.
• Prevent further thread damage: Replace unsuitable or damaged components before reassembly.
• Maintain the correct thread specification: Preserve the original M10 × 1 connection.
• Support engine restoration: Renew damaged original components during classic Porsche repairs.
• Preserve factory construction: Maintain the specified Porsche oil system arrangement.
• Support long-term reliability: Restore a sound mechanical closure at the relevant connection.
• Maintain Genuine Porsche quality: Use an original equipment replacement rather than an unverified substitute.

Replacement is recommended when the plug is cracked, distorted, corroded, cross-threaded or unable to provide a secure seal.

If leakage is caused by the receiving component or the associated sealing arrangement, replacing the plug alone may not resolve the fault.
