ok so i just got a 92 firebird... v6

now 1st i wanna say im not f body buff..

Gbodys, turbo regals and dsms.. i know alot...

ok so my problem...

i have this ungodly loud whistle....

i check all the vacuum lines and so far i cant find the problem..

so i think its vacuum leak why..

beacuse it only does it when at vacuum...

after 1200rpms it starts to quite and by 15/1700 its gone....

it sounds like its comeing somewhere near the back like by the distrubuter

i have no idea but it SOOOO irritating driving my car..

any ideas..

acuallly maube i didnt check them all..

cause i looked here... http://www.autozone.com/az/cds/en_us...rInfoPages.htm

and tehre are more than whats pictured..

such as lines going to the brake booster and the mas

been doin research.. could be a cracked intake gasket..???

i tried to take the intake off... took out the ten upper bolts..but didnt cme off.. is tehre any hiddon bolts

update...

i know its somewhere near the back side pass fuel inj.

when i sprayed carb cleaner on the last inj. it stopped..

i dont thinki its the inj. i think its somewhere near it...

is there a trick to getting the intake off?

Just remove the 12 bolts and "jiggle" with it, the gasket will have sucked on to the intake and heads, just take an rubberhammer and hit it gently and the intake will loosen..

Intake gasket leak is pretty common. So it may be between the head and intake it takes in some air..

pretty cheap gasket isnt it?

man i need sleep its like 230 in the morning

Get an vacuum gauge and have your vacuum checked to, should put out around ~18 / 20 on a healty engine.

and you did say v6, wonder if it got 12 bolts, maybe its just 10 bolts on that one..
