1996 GMC Jimmy making extremely loud weird noise HAVE VIDEO
thx for the pic but im still unsure of where its located? sorry im still learning, but is the brake boost line coming out of that big black round thing on the firewall? is the line I have from the lil line to the left of it?
If possible: can someone show me exactly where EACH end of the little vacuum line goes? like take a picture and use paint to draw a red arrow or something?

In the first pic that Spree linked you can see your same line coming off that big black round thing on the fire wall (brake booster) and disappearing under a bunch of wires and what not above the intake. I would draw on that picture for you but I'm on my phone and don't have my computer with me
and its all good don't be sorry i didn't know what anything was before i got on here either :P
Edit: Ok here is the best i can do for now, i had to figure out my new phone lol

This is a good suggestion! I looked all over my engine again and can't find a 1/4" line that looks like that one.
-ok so first off I cleaned the EGR valve (pretty dirty) but noticed my gasket didn't have a screen like the one in the DIY tech article on here, that bad?
-tried propane test but didn't find anything
-took two pictures, first to show the area where hose was found just laying on other lines. and 2nd to show a better location of the annoying noise.
EDIT- The last picture I just took, I found that the washer at the end of the brake boost that meets the intake is ripped. Could this cause that noise?? will be replacing it shortly

that could make the noise. Put your hand over the hole and start it to see if that is it. Its casuing a vacuum leak regaurdless. Have you tried running it and spraying starter fluid around there to try to find a vacuum leak. Please dont smoke while doing this, lol
