I fired it up, much better! no leak. However now I have that dreaded whistle as soon as you rev it, and then rpm comes down it goes away... Well some of the time.
It wouldn't be the result of the "black" anti-slosh thing I installed? I assume no. Carb base plate gasket to center section "looked in great shape" when I took it apart. All 6 screws with correct locking washers tightened. My guess is the intake manifold gasket to 1" spacer, on both sides. I've never troubleshooted a whistle before.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
