broke bolt in the block

ok i was taken my header off and broke a post that the bolt hards on to.

any ideas of how to get the rest out wiht out hurting the hoel or to jsut get the bolt out?

Is any part of the bolt sticking out above the surface of the block? or did it break off flush with the block? If it's sticking out, you could get someone to weld a nut onto it and then turn it out and replace it.

If it's actually broke off at the block or even a little inside, any machine shop or good mechanics shop should be able to pull it out for you.
It's not all that hard with the right tools and would just take a few minutes.

its a little inside and its the end one on the left well it hurt if i put a header on and drive it to a shop win i put the hole car back together? well it leak to bad?

it should be fine to make it to a shop... just don't break off any more

Depending on how easy the access is to the broken bolt, and the tools they have available, they may need you to take just the head into the machine shop. I would ask them first. I've extracted bolts from the aluminum head and block before, but it's definitely not something I would recommend to others. One mistake, and you can screw up your block. Aluminum is much softer than steel.

fixing this is a pain but doable.
What you can do is pay to have it fixed or save your self on the labor cost and do it your self.

If youdo it yourself you are going to need to get a bolt remover/extractor kit, sears sells them. it comes with drill bits and these things that look like funny drill bits (the extractors). What you do is pick out the drill bit that is a little smaller in size than the bolt you are removing and drill into the bolt thats in the block, go in about 1-3cm depending on how much is left in the block. then you take the extractor bit and put that in the hole you drilled and turn it with a wrench or vice grips and it should come out, you may have to use some penetrationg oil on it.

I recently installed a header onto my car and i clean snapped off a stud. It didnt hurt none and i torqued all other bolts to spec with a new gasket and luckily i didnt have any exhaust leak. i broke the stud middle/bottom.. but if u broke it on a diff location like the corner of the header u might have a leak good luck

Use a bolt extractor to get it out, its not that hard. I'v done it many times.

I'd like to say use acetylene but that's not too smart when it's the engine head... I've broken so many bolts cleaning/rebuilding my rear suspension and the torch always worked best to get it apart... I broke 2 extractors trying to get out one 10mm bolt (high strength) and I'd reccomend you buy the most heavy duty one that will fit the bolt so you can really torgue it and get out the bolt, then possibly rethread the hole with a tap if the threads are messed up. WD40 and other similar fluids will help a lot, and possibly 'lightly' heating with acetylene and letting it cool might loosen it up if the threads are seized together. I`m sort of a pyro so I`m biased towards the torch but you really should leave that to the very last resort as you can do a lot of damage with it if you don`t know how to use it properly... (still my favorite tool)
anyway good luck

aluminum head- dont torch it.
