Welcome back:
The exhaust manifold is definitely cracked. You could try JB weld for exhausts, but I don't know how long or if it will work.
As far as picture two, it's hard to tell what I'm looking at in the picture. It may be related to the PCV. If you follow one of the hoses, where does it lead?
Let me know.
