Quick Help! Stripped Torx bolt removal!

So I'm trying to replace the crank sensor on my '99 Viggen. I have the part, and the tools. Seems simple enough, definitely something I can handle. Then I get down in there, and I see that I am not the first to tinker with the CKP....great, looks rusty and crappy. I get the T30 bit in it, and I move it a around a little by hand. Loose, and won't hold any torque. Now I'm super pissed.

How do you remove a stripped Torx head? Any help would be appreciated.

Drilling is not an option. Have you ever seen where the crank sensor is? I might JB weld something to it, the only problem is the bolt head is rusty. This sucks, nothing ever goes right when I'm working on my car.

You could always take a hack saw to it, and make a flat head on the head of the screw. But am sure you can't fit a hack saw in there.

if u cant drill it out...i used a nice sharp pair of channel locks that dig into the metal to get a good grip to crack it loose. best $40 i ever spent. some pb blaster wouldnt hurt either...that stuff is amazing.

Tried the vise grips, none would fit. Tried jamming a flat-head screw driver in it - no dice. So, I made one last try at it with the socket, u-joint and extensions. I jammed in down in there good, lightly tapped on it with a hammer and I felt it "seat". I then twisted it off ever so gently. I think what helped the most was the PB blaster and then pounding of the bolt head with the pry bar and hammer.

I have a friend of mine coming over to drive me to the hardware store to get some kind of fastener to put in because Saab Nashua North does not carry the bolt (duh).

Thanks for the quick replies, it's nice to know there's a wealth of ideas available around here. I really appreciate it.

Not sure if you got it out, but I had a similar problem.

Take a flat head, and use it to chisel the outer edge of the screw. Eventually it will losen, and you can continue to do this to turn the screw out.

Hope that makes sense. Basically your using the flat head to get a grip on the outer edge of the screw. Hammering the flat head will give the force necessary to unscrew it.

Edit: Read your latest post. Glad you got it out.

I did something like that, except with a long pry bar and a hammer. I whacked the pry bar while holding the end of it on the bolt head. The vibrations helped break it loose and after that it came out without much effort at all! It's on and it runs/starts just like it should, even in today's 90* weather.
