I have searched for what vaccum hoses i can remove and cap off to clean up the engine bay and i cant find anything about it. I always see that people do it, so i was just wondering what all do i do because i have my intake manifold off right now on my 87 sy N/A. Thanx.

 

go permix that loses all the oil lines. most vac lines are need unless you take out your smog pump AKA(Air pump) also there is the toggle for the 5/6 port you can remove and lose some lines in there.

 

There are lots of threads covering this. Search for common keywords like "solenoid" and "rats nest". Look in the archives too. I know there's at least one write-up in there.
