Doubts about specific AE86 parts

[Bean]

Not sure if the cam case breather hose is just disconnected or if he ran it to a catchcan/ground.
Seems to me it's a bit like the rear bumper the person just made things work without taking much care. Just by the looks I wouldn't trust most of the rubber parts in that picture. Maybe it's just dirt but I think a lot hasn't been touched or cared for in the laat 30 years.
