Eazy outs suck... go to wallmart, go to the tool section and get a grip it... same concept as a easy out, but more duraible

The easy out is stuck in the bolt and i dont want to buy a expensive drill put to get it out, i think im gonna do a heilcoil but back on track, can someone tell me what the thread and pitch are of the exhaust studs :-/

Try this product. I have not tried it yet. But, I heard good things about it.

M10X1.25

There is a toyota stud for 1/2 the cost

However your already screwed, im in the same spot.

You need to remove the head, build up a bead of weld on top of the stud, then weld on a angled alan wrench, or a hex nut to the stud.

Id then run the car for a little bit, and take a candle and hold it up to the newly welded nut.

Should come right out.

Dont do a helicoil/drill out the stud because the stud most near the dizzy is only sperated by a few mm of aluminum before you hit the water jacket. You wouldnt know you hit the jacket untill you slowly start loosing coolant, thus start to over heat because most of the time it doesnt even leak, it just evaporates and there is 0 trace of a leak.

The stud that i broke is the farthest one towards the firewall, do you think there is still a chance of hitting a waterjacket?

Its probably the same in depth, maybe 1mm more in width.

You need to do the weld trick, unless the engine is out, either way your not going to drill that broken ezout, no bit in the world is going to tap that puppy.

Go to homedepot, rent a welder for $40 a day, 30 minutes later stud will be on the floor.
