The oil filler and breather assembly allows engine oil to be added to the engine while also supporting crankcase ventilation. It helps manage oil vapour and pressure within the engine, allowing the crankcase to breathe correctly as part of the engine lubrication and ventilation system.
Functions
• Replaces the oil filler and breather assembly
• Provides the engine oil filling point
• Supports crankcase ventilation and breathing
• Helps manage oil vapour and internal crankcase pressure
• Supports correct engine lubrication system operation
• Replaces damaged, corroded, blocked, leaking, or missing original assemblies
• OE Match replacement for Porsche 356B and 356C engine restoration.
Why Replace This Part?
Oil filler and breather assemblies can corrode, block, leak, become damaged, or go missing due to age, engine heat, oil vapour, moisture, and previous repairs. A faulty breather can contribute to oil leaks, poor crankcase ventilation, oil mist, pressure build-up, or an incomplete engine bay appearance. Replacing the assembly helps restore correct oil system function and original-style engine detail.

• Oil vapour, misting, or leakage is present around the breather area
• Crankcase ventilation is restricted or not working correctly
• The engine oil filler area is being restored
• The engine has been removed, rebuilt, or resealed
• Incorrect or non-original breather parts have been fitted
• The vehicle is undergoing Porsche 356B or 356C engine bay restoration.
Where it fits on the car
This oil filler and breather assembly fits on the engine oil filler / crankcase ventilation area on Porsche 356B and 356C models. It forms part of the engine lubrication and breathing system.
