With stock cam you should generally see 20-26" of vac at idle

let us know where it was if/when you find it!, I,ve got a hiss behind my stereo somewhere, I think its the temp switch just not looking foward to pulling the dash apart.
cheers kenny

ive looked high & low, and found it to be a bent & cracked metal line on the manifold, and idle bleed gasket leaking and then the jackpot! the switch itself was leaking but only when turned fully to cold, if turned clockwise even 1/2mm it stopped hissing, so I'll replace that when "I get around 2 it"
I know what you mean bout the dead globes! there must be 5 or more in my dash too.
cheers kenny
