Diagram ref no 18
The oil filler cap closes and seals the oil filler neck after engine oil has been added. The O-ring helps prevent oil vapour escape, oil seepage, dirt entry, and poor sealing within the engine lubrication and crankcase ventilation system.
Functions
• Replaces the engine oil filler cap, includes sealing O-ring
• Seals the oil filler neck
• Helps prevent oil vapour and oil seepage
• Helps stop dirt and debris entering the engine oil system
• Supports correct crankcase ventilation sealing
• OE Match replacement for Porsche 986 Boxster and 996 oil service.
Why Replace This Part?
Oil filler caps and O-rings can wear, harden, crack, loosen, or lose sealing ability due to age, heat, oil exposure, and repeated removal during servicing. A faulty cap or seal can cause oil vapour smells, minor oil seepage, poor crankcase sealing, or contamination risk. Replacing the cap and O-ring helps restore proper oil filler sealing and a clean engine bay.
When to Replace This Part
• The oil filler cap is cracked, loose, missing, or damaged
• The O-ring is hard, flattened, split, or missing
• Oil vapour smell is present around the filler area
• Oil seepage is visible near the filler neck
• The cap no longer tightens or seals correctly

• The vehicle is undergoing Porsche 986 Boxster or 996 engine bay restoration.
Where it fits on the car
This cap and O-ring fit at the engine oil filler neck on Porsche 986 Boxster and 996 models. It forms part of the engine lubrication sealing system.

Although relatively simple, the oil filler cap performs an important sealing function. A correctly fitted cap helps prevent engine oil from escaping while protecting the lubrication system from dirt, moisture and other external contamination.
What This Product Does:
The oil filler cap seals the opening used when adding engine oil.
Once installed correctly, it helps:
- Close the engine oil filling point
- Prevent oil from splashing or escaping
- Reduce the risk of dirt entering the engine
- Reduce moisture and external contamination
- Maintain the intended sealing of the lubrication system
- Keep the engine bay cleaner
- Provide convenient access during oil servicing
The cap must fit securely and its sealing surface must remain in good condition.
Symptoms Of Wear Or Failure:
Oil filler caps are exposed to engine heat, oil vapour and repeated removal during servicing. Over time, the cap or its sealing components can deteriorate.
Common symptoms include:
- Oil residue around the filler opening
- Oil leaking or misting around the cap
- Oil staining nearby engine components
- Cap becoming loose
- Cap no longer tightening securely
- Cracked or damaged cap
- Hardened or deteriorated sealing surface
- Damaged threads or retaining features
- Cap becoming difficult to remove or install
- Visible deformation
- Missing oil filler cap
Any persistent oil leakage around the filler opening should be investigated rather than simply cleaned away.
Why Replacement Matters:
Replacing a worn or damaged oil filler cap helps maintain the integrity and cleanliness of the engine lubrication system.
A new cap can help:
- Restore a secure seal
- Prevent oil leakage around the filler opening
- Reduce oil mist in the engine compartment
- Protect against dirt and moisture
- Keep surrounding engine components cleaner
- Replace cracked or deteriorated material
- Restore secure engagement with the filler opening
- Maintain reliable access for routine oil servicing
A missing or severely damaged filler cap should be replaced promptly.

A lockable oil filler cap with beautiful engraved OIL inscription for side filler modification
Fits:
Porsche 911 1973 - 1989
This OE Match side filler oil cap kit is a replacement oil filler cap kit for Porsche 911 models from 1973 to 1989. It is designed for the side oil filler system and helps restore correct sealing, appearance, and function of the external oil filler arrangement.
The side filler oil cap closes and seals the oil filler opening, helping prevent oil vapour, oil mist, dirt, and moisture from entering or escaping the oil tank / filler system. A correctly sealing oil cap is important for maintaining the integrity of the dry-sump oil system used on classic Porsche 911 models.
Functions
• Replaces the side oil filler cap assembly
• Seals the oil filler opening securely
• Helps prevent oil vapour and oil mist escape
• Helps protect the oil system from dirt and moisture entry
• Restores the correct OE-style oil filler appearance
• Supports proper dry-sump oil tank sealing
• OE Match replacement for service, repair, or restoration.
Why Replace This Kit?
Oil filler caps can become worn, loose, corroded, damaged, or lose sealing performance over time. A poor seal may allow oil mist, vapour, dirt, or moisture to pass through the filler area, and can leave the vehicle looking incomplete or incorrect during restoration. Replacing the side filler oil cap kit helps restore secure sealing and the correct classic Porsche finish.
When to Replace This Kit
• The original side filler oil cap is missing or damaged
• The cap does not seal securely
• Oil vapour, oil mist, or residue is visible around the filler area
• The cap is corroded, loose, cracked, or heavily worn
• The oil filler neck or surrounding oil tank components are being serviced
• The vehicle is undergoing Porsche 911 oil system restoration
• The car is being restored to an OE-style appearance.
Where it fits on the car
This kit fits at the side oil filler opening on Porsche 911 models equipped with the relevant oil filler arrangement. It forms part of the oil tank / filler neck system and should be installed according to the factory oil system layout.
