Hey gutza,
They're for the Barra, there are two of them, the rear one is the
PCV valve and the front is just a breather which vents back into the intake.
I want to fit a catch can to minimise oil build up in the intake, the rear fitting just presses in to a rubber grommet, but this front one is metal on metal and doesn't seem to be anywhere close to being the right size.
Just wondering if I'm missing something really.
