On the Skunk2 Intake manifold for a Bseries, how do you turn the nipple for the brake booster to point down? Is that nipple molded in there or is it threaded and can I loosen it? Im trying to clean up my engine bay.

 

i did the same thing. its not threaded. its pressed in, use a rubber mallet and hit it...mine got real loose and i took it out and used indian glue. redish tar glue stuff that seals and permanents the stuff. upside down and clean but check out www.kenskustomchassis.com they sell boosterless master cylinders..
