i just bought a 2000 trans am and there is a vacume leak on the front of the intake where (i think) some sort of egr line goes to the intake. what gasket do i need and how do i make it STOP?

on the top front of the intake?

there is a little rubber seal that can be tough to get seated correctly, just have to remove that bolt and pull up on the tube and see if the seal is on correct

still can not get the vacume leak fixed

Did you get a new EGR gasket (or is it an O-ring?). The EVAP and PCV are on the front of the manifold too. There's also the MAP sensor, brake booster hose, and A/C vacuum line in the back.

it is the one that mounts right on top egr tube i think. i am pretty sure it is the reason i am having a idle problem plus when i get to about 4000 it starts to make a whisleing sound.

onebad400

well the new o-ring fixed the problem with my idle but it has been a day and now it is starting to whisle again what could cause the whisle? also is there suppose to be one or two bolts holding the egr tube to the intake, and can anyone send my a picture to compair mine to?

Nope, just 1 bolt. It's hella easy to yank that brass threaded piece out of the manifold, so don't put the Vulcan death grip on the wrench.

take some carb cleaner and hit a little at a time on the areas that you think might be leaking.. if the idle changes.. you might found it that way.. is there any cracks around the areas that you are looking at ? maybe very small ones?

for sure do not tighten too much...I was also surprised a long time ago when i saw only 1 bolt..thought i got shortchanged at factory or something. ...make sure u have that ring on right..there IS a up and a down to it. one side has a type of groove..the other doesn't.

onebad400

which way is up the groved side? i just installed it so the taper of the oring matched the taper of the intake.

Take off the pipe and be sure to look for cracks in the manifold, have seen other people have the same issue. Are you POSITIVE that its the EGR hookup? Many places on the manifold can have a vacuum leak, like blur said there are also hook-ups in the back and if they aren't on all the way they will give you a vacuum leak. Also make sure all of your manifold bolts are tight. If its your EGR hookup you can take a small amount of RTV sealant and put it around the OUTSIDE where the EGR tube meets the manifold, that will give you an air tight seal that will fix the leak if thats where it is.
