But if I blank it off, there is no sense having the banjo fitting above the BOV. So, it must have a purpose. Don't know what tho, or what mine should be hooked into.
Closing it off helps the boost leak situation, but is probably not the long term answer.
There is a long line going from intake into vacuum brake servo. There should be a check valve as as well. Other from that, there was a thin line going from banjo bolt , trough T-orifice (and damper disc) and then blocked. My memory is flaky but I'm quite certain mine was blocked off.

The disc grommet has probably a membrane of some sort in it, acting as a damper.
Thank you for your time,
