EFI Valve Cover: Nipple below the cap?

[monk302]

Hey everyone,

Question, so on my EFI valve covers I had purchased for my EFI swap there is a nipple below where the cap is and where you would pour the oil into. Where does this get attached to? It appears that a small diameter hose should be attached but I don't know where it would go. Anyone have any ideas?

That nipple's hose goes to the airfilter for the PCV system's fresh air supply.

It goes to the 90 degree bend tube in the top of the throttle body.

Looks like the clue was in the questions...?

I can be a smartass on other people's knowledge.
