Crap, broke a bolt in the head

[Blue)(Fusion]

Hi,

So I was dedicated tonight and tomorrow to replace my cracked intake manifold. Everything was going great while removing the parts until I got to the rear passenger side 10mm bolt on the intake manifold. The bolt snapped as I was trying to get it out. It broke just above the cylinder head.


What can I do to get this out? I tried some pliers, but to no avail as I can not get a good grip on it. I am desperate for tips and ideas as I really don't want to have to replace the head.

Here's what it looks like:

Sorry about the image quality, I only have my phone available.

The vehicle is a 2000 Grand Marquis.

Maybe this will help. My son bought at sears a set of bolt remover tools that have hardend like teeth to grab a worn stripped bolt head. I know you have a broken bolt but maybe one of the smaller removers like for 8mm for example use gauge if you have on bolt for size or go to store with bolt in hand for fit. may just fit the bolt itself. Its a tough spot to be in I know you need it to move and not break again with alum head. I would spray also since you now have access. Most would heat head I would try to heat only bolt so it expands possibly breaking its bond with head maybe take old exhaust gasket and slide over bolt trying to keep heat only on bolt. once hot spray with (I LIKE liquid wrench penetrating oil yellow can)to cool then try that wrench from sears if it doesnt move repeat until it does now you need patients. hope this helps I know how you feel been there Good luck

By the grace of the automotive gods, some PB Blaster did the trick. I sprayed it, let it soak, and tried a small set of pliers. The pliers broke it free and I was able to hand turn it out of the head.

Thanks for your suggestion though. I actually was at AutoZone looking for an easy out or a reverse drill bit like you mentioned and even the guys there were like "you're SOL, blah blah." Here's to keepin' the faith!

WOW thats great I know how crappy that feels in stomach when bolts break like that, put never seize on bolts when reinstalling on bottom of bolt head and screw. Glad you didnt need to go crazzy.
