Post subject:  snapped engine steady bolt in block
A few months back I overtightened the engine steady bolt to block bolt and snapped it in there, so I bought one of those temporary kits that enable you to attach the engine steady to the block by bypassing the original hole... until such time that I could remove the engine well I removed the engine on the weekend and now I've snapped an easy out in there! any ideas to get it out? can it actually be removed? its in pretty tight.

Its a really sticky situation, and snapping ezi-outs is de rigueur when getting flush snapped bolts out.

Snapped ezi-outs compound the problem, as you need to drill alongside them to use another ezi-out, the hole will be offset from center considerably, and ruin the thread, the hard broken ezi-out will ruin sharp drills and otherwise upset the process.

There are a few tricks. Heating the metal helps with a bunsen torch. Also, although the bolt is small, you might try to use a center punch to tap around the outside of the bolt. To do this you make a little purchase near the edge of the bolt (using a sharp center punch is enough), and use the same sharp center punch to try and tap it around in the direction it will unscrew. Its a little bit tricky, you don't want to chisel a gouge in the bolt, just persuade it to unscrew a little until you can get a grip on it with a pair of pliers.

cant you drill it out and either retap it to 5/16 or fit a helicoil if it ends up a bit ordinary?

Once you snap an easy out you might as well put the drill and taps away and break out the welder.

I'm no expert however I had a button headed bolt removed by welding a flat bar to it, but your bolt may be too small for this..

Weld a nut over it.

Can you throw up a close up pic of the area Jenk ?, the guru's on here might be able to make a call on how to best tackle it .

Thanks to all for the tips/suggestions... I have attached a photo to give you a better idea. I think welding another bolt to it might be the go... If only I could weld :?

I did exactly the same thing, tried welding a bolt to it - nearly destroyed the block - it's on the shelf till I can figure out a smart way to recover it :(

welding a nut to it would be the best way - weld through the centre of the nut and hope for the best

Ezy-outs are bad news if a bolt has sheared off flush. They spread the bolt and make it tighter, then BANG! they break. More so now they are cheap rubbish.

Correct way I (ex railways fitter/machinist) was trained to remove broken studs/bolts is centre pop & drill a pilot hole on centre, open that out with the correct tapping size drill for the thread, then screw a tap in to peel out the thread remains. Works every time, even for removing broken S/S bolts from alloy outboard motors.

Yep, a tried and tested method...care with a well sharpened drill bit, maybe some grinding of a flat in the centre of the broke bit so there is no chance of the drill spearing off to one side and centring the drilled hole is important for a good "outcome" :D

You might need to use a very small dremel and slowly grind the easy out first then carry on as they said above.

Jenk,
These drills Will Drill out an Easy Out.
I have used them on high speed steel many times. Easy outs are softer than high speed steel.
Believe me they will work..
You will need to set up a drill guide so you are sure to drill down the center of the broken bolt and easy out combination.
A simple drill guide could be made with a piece of mild steel with a hole in it the size of the drill you are going to use.
Bolt it to the block using the other steady mount hole and another suitable point.
Position the hole in your drill guide directly over the broken bolt hole.. Guide should be about 20mm thick
Dont try to do it without a drill guide, it will end in tears!!!
If your not sure PM me and ill send you my mobile number and talk you through it.
Dave
