Apologies for the bump guys, but thought theres plenty of info on here already rather than start a new thread.
What do people think of this setup?

Looks like everything is routed to a catch can, then back into the inlet post AFM. Bit odd to have the crank breather connected to a can then back in via intake? Most of the oil in the breather system is coming from crankcase no?
Also wen drilling the rear of the valve cover to weld on a fitting, what type of AN fittings are people using exactly and how do you avoid filling baffles with metal shavings??
