Default Snapped a Head bolt in the block

What is the easiest way to fix this problem. It happened while we were tightning the bolts. And yes they were new bolts? Just so we make this clear now.....

I am going to assume No i believe that it is below the deck. I have not pulled the heads back off. I just tightned all of the other bolts and put it back together. I know that it will not last long until something bad happens so while the car is broke I was thinking about going back in and looking at it. I just needed to know if there is anyway to fix it on my own or if I am going to have to pull the block.....

I had this happen to me 2 weeks ago. I had to pull the block and take it to a machine shop. They are still working on it...

At very worst, they will have to drill the hole, and put a stud in it.

which bolt is it? might be able to center punch it, drill it, then use an ease-out if you can get to it, but you might just be screwed

how much of the bolt came out of the motor(how deep is it)? which side, which hole?

here's a pic to help you tell us which one.

holy hell it couldnt get much worse than that! oh well, unless you can get to it well, which you probably can't, i'd say pull the motor and go from there.

if you tried to center punch it, drill it, then ease-out it, you could damage the block being at such an odd angle in doing everything

how far down past the block's deck do you think it is?

Could always try and "tack" weld it with a very thin rod and back it out to. Not the best way to go, but another option. Better be good with the welder.

As a word of caution...that particular bolt hole is made up of block casting that bulges out of the main block and can be seen when the trans and flywheel are removed. This is the first hole that will blow out when bolts are torqued with fluid in the hole. I am not implying that you did this...what I am saying is that care should be taken when working with this bolt hole, there's not much material on the backside and it is easily damaged. I have photos that show the block casting around this bolt that has been blown out. To save the block I had to machine out the upper and lower sections of the bolt hole to remove all cracked aluminum and then weld it shut. Using the TimeSert kit I re-drilled the hole and installed an insert. Good luck, this is not going to be an easy fix....
