hopefully i used the right name there - the bolts/studs used to keep the exhaust manifold attached firmly to the block...one of these bolts is snapped off, how should I remove this to replace it....how is it set in there block? am i going to have to drill it out? Any help would be great. Thanks

 

i had a bold stuck in the head and this is how i got it out...after spending forever tryin to drill it out with a bold extractor we...

grabed the drimel and put a cutting bit in it
cut a slit across the bolt wide enough to fit a flathead screwdriver
used a screwdriver to unscrew the bolt


it unscrewed really easy...like i said i did this to get a screw out of the head so i dont know if you have enough room to do this for the header but its worth a shot

 

so you're saying the part of the bolt that is recessed into the head has a thread on it? it can be unscrewed?

 

it's just one bolt....who cares

 

yes, of course that is threaded into the head. If you can cut a notch in it do so and unscrew it. somepeople have welded a piece of metal to the broken part to unscrew it. others try to drill them out using a left hand bit. others use EASY OUT extractors, might work for you.

I left mine in there, no big problemmo

 

Did you ever get it out? I just pulled the heat shield off of the exhaust manfold on my gsr swap I just got from IAS and noticed two nuts were missing, one bolt was snapped and there is some sort of sealant all over the gasket. I left Larry Jr a message but I doubt he will do anything about it.

Here's some pics:

 

always have the car warmed up when doign any kind of exhasut work. espcially on cast iron. loosen them with the car running , and then shut it off and remove them. on removeing it, I usually put in a center punch on the stud. Get is centered perfect. then dril it out to the TAP size of the hole then run a tap in there. It works really well, and is pretty fast. Get a 90Deg attachemnt for your drill for a hole like that.

 

damn talk about bringing a thread back from the dead

 

you gotta love morons that love to put silicone everywhere ......

Omg to funny. Person should realize that the exhaust gasket can be reused. And you never use silicon except on a couple rubber gaskets (valve cover, oil pan, cam seals, ect..).

 

I got the stud out. Here's a link: https://honda-tech.com/zerothread?id=567450

 

Nice writeup! I just broke a stud off when I installed my DC header just a week ago. Gonna fix it on my next day off...
