Diagram ref no 55
The 1972 model year Porsche 911 is one of the most distinctive and sought-after classic 911s. Often referred to as the "Oil Klapper", it features a one-year-only external oil filler flap mounted behind the passenger-side door (right-hand rear wing on left-hand drive cars). This unique design relocated the oil tank forward for improved weight distribution, making several oil system components—including the dipstick—exclusive to the 1972 model.
Whether you're restoring an original 1972 Porsche 911 or replacing a damaged or missing dipstick, this OE Match replacement delivers factory-correct fitment, accuracy and appearance.
What Does the Oil Level Dipstick Do?
The oil level dipstick provides a simple but essential method of accurately checking the engine oil level within the external dry sump oil tank.
Its functions include:
- Accurately measuring engine oil level.
- Preventing overfilling or underfilling.
- Helping maintain correct engine lubrication.
- Supporting proper oil cooling performance.
- Protecting internal engine components from premature wear.
- Assisting routine servicing and maintenance.
Correct oil level is particularly important on air-cooled Porsche engines, where the engine oil performs both lubrication and cooling functions.
Why Does the Dipstick Need Replacing?
Although a simple component, the dipstick can become damaged
over time through:
- Corrosion.
- Accidental bending.
- Wear to the handle or measuring marks.
- Loss during engine work.
- Fatigue after decades of use.
An inaccurate or damaged dipstick can result in incorrect oil level readings, increasing the risk of engine damage.

Common signs include:
- Bent or distorted measuring blade.
- Worn or unreadable oil level markings.
- Corrosion or rust.
- Loose or damaged handle.
- Poor sealing in the oil filler neck.
- Difficulty obtaining accurate oil level readings.
- Missing dipstick.
Replacing the dipstick restores confidence when carrying out routine oil level checks.
When Should the Oil Level Dipstick Be Replaced?
Replacement is recommended when:
- The original dipstick is bent or damaged.
- Oil level markings have become difficult to read.
- The dipstick has been lost.
- Restoring a 1972 Porsche 911 to factory specification.
- Replacing damaged oil filler components.
- Carrying out a full oil system refurbishment.

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.
