The attempt to remove the fitting may cause further damage. There are a couple of less damaging fixes you could attempt first. If you cut just behind the keeper (not sure what to call it), the piece that the PCV fitting would normally "click" to, that would get you a straight piece. If you can match a plastic pipe ID to the OD, you can glue an extension on and go from there.
Another thought, if you cut it down to the base of the fitting, taking the remaining nipple off, you could drill the base, and if there's enough material thickness, thread a plastic barbed fitting into the base. Should even be able to get that fitting in black plastic. Or you could go metal, but I don't like using metal fittings on plastic, particularly threads for obvious reasons. If there isn't enough material to cut a thread into the base fitting, you could still use the plastic threaded barb fitting and glue it. The threads will act as a guide to keep the fitting straight, once the glue sets it will be as hard as plastic and sealed. You should be able to thread it in up the hilt.
Just my $0.02 for a less risky approach.
As a word of caution, friction welding is great for making a clean looking joining of 2 pieces, but when it breaks it more often causes a lot of base material damage because no filler material is used in the joining process. If you try to remove that fitting, you will likely take a chunk of the manifold with it. Your best option to remove the fitting, is to cut it out with a high speed dremel. Again, I'd exhaust the other methods of re-using what is left before resorting to that. Without knowing what the port looked like before the fitting was inserted and joined, you won't know how much material to remove or where to remove material from. It's not something you can just put a heat gun to and pull.
