I just took the upper intake off the 87 last night. Had to replace some dry rotted/split vacuum lines as well as wanted to have an easy reach to the PCV Job is EASY - so if your dude didn't know what he was doing, that's pretty pathetic to be called a mechanic.
There is 1 vacuum line that goes from under the middle of the upper intake towards the AC compressor area (only 1 line goes this way). This vacuum line connects to the EVAP Purge Valve Solenoid.
Otherwise, going out from middle of the upper intake towards the rear of the car starts at the intake with a 1 inch long piece of line, then a plastic L, then a really long preformed vacuum line that goes into the PCV valve.
There's another vacuum line that runs from about the same spot underneath the upper intake and runs to the MAP.
There are three connections that sprout out like a tree on the side of the upper intake facing the firewall/wipers/cowling. There is 1 bigger vacuum line that appears to run into the firewall somewhere. Two remaining vacuum lines. 1 2-3" long vacuum line runs from the fuel pressure regulator over to this tree. The other vacuum line connects to the other end (which IIRC runs to the EGR valve).
Hope this helps out.
