Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)

Diagram Ref No 24
Manufactured from high-quality automotive-grade materials with an integrated oil-resistant sealing gasket, the cap is engineered to withstand continual exposure to engine oil, heat, vibration and harsh engine bay conditions. Precision-moulded to OE dimensions, it provides direct OE-style fitment and a positive locking action, making it the ideal replacement for worn, damaged or missing original oil tank caps.
What This Product Does:
- Seals the engine oil tank securely.
- Prevents engine oil leaks from the filler neck.
- Protects the lubrication system from dirt, dust and moisture.
- Helps maintain correct crankcase and oil system integrity.
- Provides a secure locking fit during vehicle operation.
- Supports reliable engine lubrication.
- Restores factory sealing performance.
- Forms an essential part of the engine lubrication system.
Symptoms Of Wear Or Failure:
- Engine oil leaking around the filler neck.
- Oil residue on or around the oil tank.
- Loose or poorly fitting oil cap.
- Cracked or damaged cap housing.
- Perished, flattened or missing sealing gasket.
- Oil smell from the engine bay.
- Dirt or moisture entering the oil tank.
- Difficulty securing the cap correctly.
- Visible wear or deterioration due to heat exposure.
- Engine bay contamination caused by oil seepage.
Why Replacement Matters:
- The oil tank cap is continually exposed to engine heat, oil vapours, vibration and repeated removal during servicing. Over time, the sealing gasket can harden or deteriorate, while the cap itself may crack, warp or lose its ability to lock securely.
- A faulty oil tank cap can allow oil to leak from the filler neck, creating engine bay contamination and increasing the risk of low oil levels. It can also permit dirt, moisture and other contaminants to enter the lubrication system, potentially accelerating engine wear and reducing long-term reliability.
- Replacing a worn or damaged oil tank cap restores a secure, leak-free seal and helps maintain the integrity of the engine lubrication system. The OE Match Oil Tank Cap is manufactured to OE standards using premium-quality materials, providing factory-style fitment, dependable sealing performance and long-lasting durability, ensuring the reliability and protection expected from your Porsche.
