The OE MATCH Oil Drain Plug M26 × 1.5 is an original-style replacement component designed for the engine oil sump of the classic Porsche 924, manufactured between 1976 and 1985.
Fits:
- Porsche 924 1976-85
Diagram Ref No 11
Also referred to as an engine oil sump plug, oil pan drain plug or oil drain screw, this component is responsible for sealing the engine's oil drain opening after an oil change.
The Porsche 924's engine relies on a continuous supply of lubricating oil to protect its internal moving components.
Engine oil reduces friction between metal surfaces, helps manage operating temperatures, carries contaminants towards the oil filter and contributes to reliable engine operation.
For the lubrication system to function correctly, the engine must retain the required quantity of oil.
The OE MATCH oil drain plug 059103193/1 provides a removable threaded closure for the engine oil sump.
During routine servicing, the plug is removed to allow used engine oil to drain from the sump.
Once the oil has been drained, the plug is refitted using the appropriate sealing arrangement, allowing the engine to be replenished with fresh oil.
The plug features an M26 × 1.5 metric thread, corresponding to the original equipment specification for the relevant Porsche 924 application.
Its threaded design allows secure installation into the corresponding sump drain opening.
Although the oil drain plug is a relatively simple component, its condition is important for maintaining a reliable oil seal.
Over time, repeated removal and installation can cause damage to the plug's threads or tool engagement surfaces.
Incorrect tightening, corrosion or the use of unsuitable tools can also lead to deterioration.
A damaged plug may become difficult to remove, fail to tighten correctly or allow engine oil to seep from the drain point.
If oil leakage continues, the engine oil level may gradually fall.
Insufficient lubrication can lead to increased friction, accelerated wear and potentially serious engine damage.
Replacing a damaged or leaking original plug with OE MATCH part number 059103193/1 helps restore the correct threaded closure and maintain the integrity of the oil sump drain point.
This replacement is particularly suitable for Porsche 924 oil changes, engine servicing, sump maintenance and classic vehicle restoration.
As an OE MATCH component, it provides an original-reference replacement for the specified Porsche application.
What This Product Does:
The oil drain plug seals the drain opening in the engine oil sump.
Its primary functions include:
- Seals the Engine Oil Sump: Closes the drain opening to help prevent engine oil escaping.
- Allows Routine Oil Changes: Can be removed to drain used engine oil during servicing.
- Maintains Engine Oil Retention: Helps keep the required quantity of lubricating oil inside the engine.
- Supports Lubrication System Integrity: Provides a secure closure for the sump drain point.
- Prevents Oil Leakage: Works with the appropriate sealing arrangement to prevent oil seepage.
- Maintains Correct Threaded Fitment: Uses the specified M26 × 1.5 thread.
- Supports Engine Reliability: Helps prevent lubrication problems caused by oil loss.
- Allows Sump Maintenance: Provides access for draining oil during servicing and repairs.
- Replaces Damaged Fasteners: Restores a serviceable drain point when the original plug is worn.
- Maintains Original Specification: Preserves the correct factory-style drain plug arrangement.
Symptoms Of Wear Or Failure:
Although oil drain plugs are durable components, repeated servicing and improper installation can eventually cause damage.
Common reasons for replacement include the following.
Typical symptoms:
- Oil droplets forming around the plug.
- Wetness on the underside of the sump.
- Oil stains beneath the parked vehicle.
- Oil residue around the drain plug.
- Continued seepage following an oil change.
- Tool slipping during removal.
- Rounded corners or edges.
- Difficulty gripping the plug.
- Visible deformation.
- Increased risk of damage during future servicing.
- Plug failing to tighten correctly.
- Excessive looseness.
- Damaged or flattened threads.
- Metal fragments around the threaded area.
- Difficulty engaging the plug by hand.
Why Replacement Matters:
A properly fitted oil drain plug is essential for maintaining a sealed engine oil sump.
Although inexpensive compared with major engine components, it plays an important role in preventing oil loss.
Replacing a damaged plug helps restore a secure drain point and reduce the risk of lubrication-related problems.
- Helps Prevent Oil Leaks: Replaces a worn or damaged sump plug.
- Restores Secure Sump Closure: Provides the correct threaded connection.
- Maintains Engine Oil Level: Helps prevent oil loss through the drain opening.
- Supports Engine Lubrication: Helps retain the oil required for normal engine operation.
- Reduces Risk of Engine Damage: Addresses leaks that could eventually cause low oil levels.
- Improves Serviceability: Replaces damaged tool engagement surfaces or threads.
- Supports Reliable Oil Changes: Provides a sound drain plug for future maintenance.
- Maintains Original Fitment: Uses the correct M26 × 1.5 specification.
- Suitable for Classic Restoration: Replaces ageing or unsuitable original hardware.
- OE MATCH Replacement: Provides an original-style alternative to the corresponding Porsche reference.

Oil Sumps – Essential Engine Protection & Lubrication for Porsche Models
The engine oil sump, also known as the oil pan, is a vital component of your Porsche’s lubrication system. It serves as the main reservoir where engine oil is stored, collected, and circulated. The sump ensures that oil is continuously supplied to all critical moving components, maintaining cooling, lubrication, and engine longevity — especially during high-performance driving.
At Design911, we stock a complete range of oil sumps and related components designed for Porsche engines of all generations. Manufactured from high-strength aluminium, steel, or composite materials, these sumps deliver excellent heat dissipation, resistance to vibration, and durable performance in both everyday driving and motorsport applications.
Whether you’re restoring a classic air-cooled 911, maintaining a Cayman, or upgrading your GT model for track use, our oil sumps provide long-lasting reliability, precision fitment, and protection against oil starvation.
What Does an Oil Sump Do?
The oil sump collects and stores engine oil at the base of the engine, keeping it ready for circulation by the oil pump.
Core Functions:
- Acts
as the oil reservoir for the lubrication system.
- Collects
and filters returning engine oil after circulation.
- Dissipates
heat to help regulate oil temperature.
- Supports
oil pressure stability during acceleration and cornering.
- Protects against oil starvation under high-G conditions in performance driving.
A properly functioning oil sump ensures your Porsche’s engine runs smoothly, efficiently, and reliably under all conditions.
Why Do Oil Sumps Fail?
Oil sumps are constantly exposed to heat, pressure, and road debris, making them vulnerable to damage and degradation over time.
Common Causes of Failure Include:
- Impact
damage from road debris or speed bumps.
- Oil
leaks caused by worn gaskets or cracks.
- Warping
or corrosion due to heat cycles and contaminants.
- Thread
damage around the drain plug area.
- Oil starvation issues in performance or track use if baffling fails.
Symptoms of sump problems can include visible oil leaks, low oil levels, burning smells, or oil pressure warnings — all of which indicate the need for inspection or replacement.
Why Replace Oil Sumps?
Replacing a damaged or leaking sump restores reliable oil storage, sealing, and temperature regulation. Our oil sumps are engineered for superior strength, thermal efficiency, and leak prevention.
Key Benefits:
- Restores secure oil containment and circulation.
- Prevents oil leaks and starvation.
- Improves cooling and oil pressure stability.
- Constructed from durable, heat-dissipating materials.
