The hole in the rear is a separate issue from the fitting in front.

The rear hole sucks (vacuum) air out of crankcase. You need to let air in so on the front you drill and tap a hole in valve cover/cap/ or in sideways into LIM. This lets the air into the crankcase. This hole in front connects with a hose to throttle body.
