Does anyone have a picture of where the rocker cover breather goes to on the right hand (drivers side) bank? The one on my car has been chopped about for an old LPG install and I'd like to hook it back up to its original position.

the rocker cover vent goes to the intake before the throttle body (not under vacuum)

As 07GTS has said, here are some diagrams, from the Holden VT/VX Service Manual:

Well I found out what the previous owner had done. For some reason they had removed and blocked off the breather hose that goes from the right hand side rocker cover to the throttle body. (pics attached)

I have now removed all of this and reconnected it with a new piece of hose so it's doing its job again
