How often are you snapping bolts??!! You can try an "EZ out" or just search for a screw extractor or left-handed drill.

If you're snapping many bolts, maybe you're doing something wrong or using the wrong grade?

"Easy Out" is an oxymoron -- they are rarely easy. Do a search, there are many good threads on screw and bolt extraction.

It was anything but easy to remove 2 easy outs from intake manifold to cylinder head bolts. I think welding a nut on the broken bolt is always a sure way to remove it.

Maybe I should knock on wood here, but I have had great success with ez-outs. The way I use them is as follows. Whenever possible I bring the item with the broken bolt to my drill press and utilize that. I will start with a small hole in the middle of the broken bolt and work my way up to as large a hole as possible. I then SOAK the broken bolt with PB Blaster. I then use the largest ez-out possible to minimize the chance of breaking that too. By drilling out the broken bolt almost entirely, all that is really left is the threads so the likelyhood of breaking the ez-out is very small. It is time consuming, but it beats torching the things out, redrilling and tapping for the next size up.

Any chance this was a Jeep Wrangler?

Also, that only works if there is some bolt left exposed. I always seem to break them flush with the surface or inside the bolt hole.

Corvette. Made a simple intake gasket swap a nightmare.

Soaking any questionable bolts before attempting to remove before you break them and giving the pentrating oil plenty of dwell time will help avoid the problem. Heat also works wonders. Also, smacking the bolts with a punch and hammer to loosen corrosion will help prevent broken bolts. Notice, all my advice is about prevention cause extracting broken bolts is a pain. If you have a bolt that seems suspect, alternate loosing and tighting the bolt. I used to use PB Blaster antil a found a product called Free All. As much as I liked PB, Free All is better.

You'll have to center punch the broken bolt. Then start drilling it with the smallest bit and work up to the biggest. If you start going off center you'll be SOL.... Use a good quality extractor and you'll be fine.

Very strange those bolts broke. Unless they were cross threaded when installed.

Steel bolts in aluminum heads - it'll happen. I helicoiled EVERY intake/head bolt hole after that experience.

And back on topic, I agree with the center punch technique. Invest in some good cobalt drill bits and tapping/cutting fluid. Also, as aforementioned, soak any potential headaches in your choice of penetrant.

Yeah the bolts around the coolant passages... seeping gaskets with corrosive coolant. Been there done that on some water pumps.

I had to once change a head on my Neon because the ******* "dealer" mechanic over torque the cam caps, then half assed the install of the helicoils. So all the bolts were loose. To top things off he managed to cross thread every single intake manifold bolt, which most of them broke.

I used the method I posted... it worked good but very time consuming.

This is that often spoken about, but RARELY used method of "Doing it right the first time". Most people are in a rush when they break off the bolt/screw, then try to rush the 'easy out' procedure....ensuring it will only get worse.

Also, before center punching, if you can, hit the top of the broken bolt with a die grinder or Dremel and a small stone to square it up and put a slight dish in it. IMO, the toughest part of the whole process is getting the hole drilled center and square. This is made even tougher due the fact that bolts rarely break off square and clean (for me anyway).

Never had much luck with easy-outs. Never had one break on me, but I can never seem to get them to bite - they just end up reaming the drilled hole.
Always had much better luck with these, found at Autozone of all places.

Use the biggest ez-out you can and tap that with a hammer in the hole to help it bite. I have a drawer full of ez outs I love them!
