Engine Hiss
I recently did some major work to my 1986 944 and went for a "test" drive tonight and when I was driving I noticed a HISSING sound but went away for the most part when I accelerated...where is it coming from?

Hiss
It is neither a vaccuum leak or snakes...I checked for the snakes and it is still too cold here for them next, I checked all the vaccuum lines and none are seperated to leave an opening...what next?

your average wrencher...

leaking vacuum line that runs your climate control? looses vacuum when accelerating (as opposed to a closed throttlebody=high vacuum) do the vents or anything change, like flow wise?

uh, stick your head in the engine bay and see where it's coming from?
 A general idea of location might be helpful... |
