Well I do believe I may be SOL this time...Not only are the remains of the thermo bolt still stuck to the threads, I've managed to strip the heads on three torx bolts while trying to remove the manifold...managed to massage one out but the two at the back of the right runner are shot...and ideas? I'm not even sure what to do now so I'm completely open to any ideas...thanks in advance

take the next big size and hammer it into the stripped bolt. Worked for me.

 

I rock

I think you may be closer to me than anyone i've seen on here, if you've heard of it, i'm from north judson, about 35 minutes south of plymouth. Where do you go to school?

I may no longer rock if this keeps up!!! Well I've tried hammering the T45 on, hex head sockets, flathead screwdrivers, allen wrenches with vice grips, the works. I hate torx!! If I ever get these things out I just might pay Totally Stainless the $85 or so to get a hex head bolt set for tpi. Does anyone have any advice for drilling out torx bolts?? (not something I'm eager to do!)

I'm actually a senior at Notre Dame...I went to Concord for high school I'm about 45 min north of plymouth...

 

Had a similar problem. Tried all kinds of tricks that didn't work. Impact driver, heat, larger torx bit, etc.

Ended up grinding off the heads with my Makita High Speed grinder and carbide bit.

Funny thing, once the heads of the bolts were ground off and the manifold removed, I could unscrew the 'studs' that remained with my fingers.

Wow thanks for the idea - you might have just saved me a bunch of cash. A guy at the machine shop asked if I could drill off the heads of the bolts and I can't but it never occurred to me to use my trusty dremel and that damn expensive carbide grinding bit I REALLY should study for finals tomorrow but I just might have to take a car break hehe. Thanks again!
