Oil Drain Plug. M 26 x 1,5.

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.
