WTF. I haven't seen one diagram where that little hole at the bottom of the BAC was connected to a hose or line or anything. Please explain. Diagram below.

 

That's the air bypass screw on turbo BACs. Whoever drew that diagram got it wrong since it's obviously an NA motor in the pic.

 

It's not a hole.
It's basically a blind plug.
Non-turbos don't have an adjustment screw there, so it's nothing.

That diagram isn't wrong mate, I screencap'd the FSM and added the caption.

I'm an NA, so that's why it looks like an NA motor. Since I've never worked on an RE yet, that explains why I didn't know what it does

Thanks for the info Ted.
