Broken manifold bolt

Hey guys, I've got a 1985 Trans Am WS6 that I'm putting headers on, and I was wondering if you had any tips for a broken manifold bolt. Apparently I have broken one of them off halfway. I don't want to wrench on it with pliers because that would probably just strip the bolt and accomplish nothing.




The broken bolt is next to the number 5 cylinder




Additionally what is this dohickey? I have no clue, thanks.

this is a temperature sensor. Either for the indicator on the dash or for the computer...

Re: Broken manifold bolt

As far as the bolt goes, there's a few things that you can try, depending on how much thread you've got to work with. All of the options are best used with liberal amounts of heat and penetrant oil.

1) Two nut method -
(35s)
2) Cut a groove in the end of the bolt\stud, and try backing it out with a standard screwdriver.
3) Using all of your might, clamp a pair of vicegrips onto the bolt and try to back it out.
4) Drill & Tap

Don't bother with easy outs if you can avoid it.

Re: Broken manifold bolt

Start by spraying it with PB blaster or something similar now and a few times a day until you work on it. Next if you want to take the standard approach you can use a craftsman bolt out kit or you can weld on a nut as it looks like there is a fair amount sticking out. Use some heat as needed.

I use these bolt outs all the time to remove studs like that

Aren't those usually used to remove stripped heads? Never tried using one on the shaft.

Re: Broken manifold bolt

Once the head of the bolt is gone, the inside of the "socket" is tapered and as you turn it to remove, it continues to go deeper onto the stud and grips even harder. Trust me, they work fantastic!

Re: Broken manifold bolt

Weld a nut to the end of the broken bolt, heat up surrounding metal, spray a lot of pb blaster on the bolt and then try and twist it out. That's how I get snapped bolts out at work

Re: Broken manifold bolt

I have two sets of those... One Irwin and one Crafstman. Never thought to try it farther than stripped heads. You learn something new everyday!

Re: Broken manifold bolt

Can you use the bolt as a stud? If you put the header on, is there enough threads to screw on a nut?

So I bought a set of those and let me tell you what that's the best 30 bucks I've ever spent and I'd happily do it again. Ten seconds and a breaker bar and that baby was out, big time thanks to all the people who helped me.

Best tool ever, I have used them to remove a rounded bolt that cracked another socket

Re: Broken manifold bolt

This spacer came from ... somebody... as part of a package.



Those are Edelbrock TES, that I had on the car A LONG time ago.

I made more, later, out of some size of water pipe nipple. For some other kind of headers, SLP maybe. Looked pretty much the same except it was more a piece of pipe than rolled-up sheet metal. w/e. Bought it at the home improvement store (aw-aw-aw-aw-aw) and cut to length. Much too eeeeezzzzy really, I feel embarrassed telling you this, you'd have figured it out eventually, next time your eye landed on a piece of pipe. (no, that not THAT kind of a piece of pipe)

Thank you for your info! I had seen this thread whilst searching for my answer...
