Hey guys, I just recently bought an 87 GT vert. This thing has some major vacuum issues. I have looked at the vacuum diagrams in my chiltons... but I can't tell a damn thing from it. Here are pictures with all the vaccum leaks I have. If you guys could let me know what goes where, that would be awesome! Thank you!
p.s. I just bought a pcv valve, and I know it's located behind the intake manifold, but I CANNOT freakin find it and I'm sorta irritated. so if someone could toss up a pic of it or be really descriptive for me that would be great. Thanks again!

Nobody knows? Any help would be greatly appreciated... The idle is all over the place

The top two pics look like connections for the smog pump that is most likely no longer there. These do not need reconnected unless you want to hook the pump back up. Just block them off with something that will not leak. The others look like your major vacuum problems. the one that hooks up to the egr if it's not hanging somewhere near it, comes from a solenoid on the pass. side, but Im not sure if it's the one in pic number 3 near the strut or if it's down lower. I would go look at mine for you , but it's in the shop right now. There is a picture of an engine up in the stickys on this forum that shows the whole engine bay and labels all the parts. I don't know if there is enough detail to see what you need, but you might want to check it out. The thread is called "engine map (location of parts)"

Ok so I don't have to worry about the top 2, they're for the smog pump. (I'll cover those up) I checked that picture, and I can't tell from it which hoses come from the egr, or where the loose ones I have go to!

ricepatrol

I can accept that maybe nobody knows where some of them go- but the egr at least... somebody has to know where that connects to! Or maybe the one coming out of the back of the manifold...
PLUS, I know the Pcv subject has been addressed a billion times, I have read every one that the search button brings up... and I still can't find where it is. I know it should be behind the manifold- possibly below pic #5 but I still cannot find it. Help!!! (sorry I'm retarded)
So if anybody can shine some light on the pcv, and the egr... **** even the other vacuum leaks that would be spectacular I don't know what I'd do without you guys here...(wait I know spend $2349230492834 at my local mechanic)

thanks fastfox for the reply*

all those parts you say you have vaccum leaks at are for the smog crap

ricepatrol

All of em? SWEEET
Save for the egr valve, which I know is important

stanglx2002

just block off the vaccum on the egr

ricepatrol

really? OK I thought that was important to have hooked up... but that shows my ignorance
Why then when people have idle problems are they told to clean the egr if it can simply be disconnected?
Or does it still function with the vaccum line blocked off?

stanglx2002

air still goes into the egr unless you put a block off put on it like i did and when you close the vaccum on the egr the computer reads it as being closed all the time. also what you might want to do is take the crankcase vent tube off and block those holes and put a breather on
