Oil Separator Membrane For 1.8 TBi Engine

Oil separator membrane for the 1.8 TBi engine of:

• Alfa 4C and 4C Spider
• Giulietta 1.8 TBi
• Alfa 159, Brera, Spider 939 1.8 TBi

A defect of this membrane causes a lack of engine power / turbo boost and increased oil consumption.
Until now this required the replacement of the complete oil seperator unit mounted on the valve cover of the 1.8 TBi engine.
Not a bargain since the OE Alfa spare part costs more than 500 EUR.
Carefully unclip the circular cover on the oil seperator to gain access to the membrane.
