My oil cap appears to be leaking and since replacing an oil cap will cost $50+ I thought I would investigate whether there is a replacement O-ring that I can fit instead..
I removed the O-ring which appears to be hard plastic square with a step in it 32mm ID, 44mm OD and 5mm thick..
It's seen better days as it's chipped and dented.
Worst case scenario I was considering trying to fit a standard O ring or possibly make something out of a gasket sheet.
Anyone else resolved this issue in the past?
