found my vaccuum leak... (help, too)

[Psych0matt]

so, this is what the end of this vaccuum line looks like:




This is where the good end was:



So, what does it go to, what do I need to do to fix it? It was loose for a while, but it never gave me any problems, i assume until it melted it had a pcv i think on the other end, but it wasnt connected to anything. help me? oh, and once this part gets figured out, would that hurt gas milage?

You should post up a pic of the part we pulled out at the meet. Might give a better idea as to what's going on. It's been a while since I've worked on a 3.4 car, so I couldn't remember where everything went .

[Psych0matt]

yeah, it sucks because my "book" is in the truck, 45 minutes away from here

yes, that is the part that I pulled up at the meet, it has since melted off the rest

Ooops!!

[Psych0matt]

anyone have vaccuum diagrams or anything like that? i checked out 60*, but nothing like that

[5speedz34]

There is one pic, but those also have the coolant/fuel lines.

I know there is another one around here.

[Psych0matt]

hmmm, that may help, are the black and white ones from the TB vaccuum lines? assuming the white one is larger, that's what im looking at i think

[Psych0matt]

well, I made a block off for now, at least so its not an open leak. now just to find out where it goes and fix it right

On my 1991 GP/SE/LQ1 there is a PCV-valve connected to the hose at your finger. I guess your´s missing?
The plastic line goes around the engine on the back to the "front end" of lower intake manifold..

[joey b]

looks like the piece that goes around the back, T's, then goes to both valve covers

[Psych0matt]

that would be the purple one, right?

[91GPLQ1]

That diagram is not right.

The purple line should switch location with the blue line at left side.

Think about it, why should the PCV-valve be connected to a valve-cover? The PCV-valve is never going to work connected to a valve-cover, it has to be connected to a manifold vacuum source....

[99RegalGS]

huh? that diagram is correct.

I think you're misunderstanding that diagram. The blue line goes into the valley of the enigine, not into the intake manifold.

[Nick1234]

isnt' there a vaccuum diagram under that hood? or is it gone. that one is more specific to your year.
