How do I get a broken stud out of a cylinder head?

Bilal asked:

I have a cylinder head off of a motor so I have all the room in the world. I have a broken stud threaded inside of the cylinder head. This is for the intake manifold I believe. How can I get the stud out? I have basic tools..drill..drill bits…and the basics nothing out of the ordinary.

The motor is a ka24e (single cam, timing is chain driven)

    Get the GRAB IT , good tool removes any broken screws or bolts. Guaranteed

    if it’s flush or below flush a grab it won’t work. you might have to take it to a machine shop jobber to get it out. if they mess it up they’re responsible. If you mess it up you have to buy a new head.

  • Tanner says:

    tie a weak magnet to a string and very carefully lower it in the cylinder, be careful not to get it stuck to the cylinder

    Take it to a machine shop and let them do it.

    Soak it down with liquid wrench or a similar rust buster.
    Use a left hand drill bit and center punch the broken stud. If you’re real lucky, the drill alone will back it out when the drill bites into the stud.
    If not, try an easy out in the hole – if that doesn’t do it, drill the hole out the same diameter as the inside thread depth and turn the remaining threads out of the hole with a pick.
    If nothing else works, drill it out and re-thread it for a helicoil.
    It’s frustrating at times how a 10 minute job can so easily turn into an hour or so.

    Got a couple answers for you the most common answer will take a little time and a new tool or two. go to the hardware store and get what is called a reverse drill bit or a bolt extractor. If you have a punch small enough I would five it a few good whacks with a hammer and punch to maybe loosen it up. Next use a good penetrating oil like kroil or anything else heavier duty than wd40. let that set for a couple hours then drill down a bit with a regular bit into the broken bolt and then change to the reverse bit. Don’t gun the drill to get it out you want to use a little finesse, and it might take a few rounds of drilling down and using the bolt extractor., but it should eventually come out.

    Easiest is if you still have a little sticking up cut a notch into the top with a cut off wheel and use a heavy duty slot head ***** driver along with the penetrating oil and mallet.
