air induction bolt broken! help!

[Soma576@xxxx]

Hey all,

well i decided to be a fool and remove my air induction manifold. looks like 
i got more than i bargained for, just like i was afraid of. the bolt that 
holds the manifold to the engine casing near the #6 cylinder (closest to the 
A/C comp) broke in half while removing it. the other three came out fine. i 
pulled the manifold off (WOW is it dirty down there.....) and there's about 
3/16ths of screw shank sticking up from the cylinder side. just a jagged 
little beastie. i've got it soaked in liquid wrench right now and i hit it 
with a hammer a few times to maybe break the rust holding it in. i tried 
getting some vice grips on it and i can get them to grip it good, but that's 
with both tips of the grips touching the casing. unfortunately the screw 
does not come out that way - it's more up and down than it is perpendicular 
to the casing. know what i mean? in other words, any turning motion you put 
on it is not the correct angle of torque to remove the bolt. 

i went to sears and bought a craftsman bolt extracting kit that will work 
with metric bolts. however i'm a little bit afraid to use it because of the 
angle of drilling is so odd - it's not straight up and and down and it's not 
perpendicular to the casing. 

let's assume the worst and that i cannot get the bolt out. what would you 
do? just screw the other three bolts down good (of course i would get new 
bolts rather than use those old stressed-out rusty things)? that seems just 
WRONG, but is that all you can do? or would it be better to make a gasket for 
the left-hand cylinder wall and hope that seals it ok? or is this stupid and 
the ONLY way is to get that damn thing out???

any tips, insight, etc are GREATLY appreciated!

Andy
