Hi all

New to the forum and started with a bad bit of news well for me haha!
I had a sheered bolt in the back of the block from the alternator bracket, I tried today to drill it out and actually managed to go past it into the water jacket! Is this a major problem and need a total new block or is there someway to fix it?

Any help would be much appreciated!

Cheers

 

Helicoil it and use some sealant on the bolt when it goes back in ,
Nothing to loose ,,

 

I still haven't managed to get the bolt out because after drilling through I put the easy out in and that bloody sheered off in the bolt so I think the Engine will need dropping out to drill it all out and then helicoil it?

 

An easy out will be hard as fuck so your have trouble getting that out! If your taking the engine out you could have the easy out and bolt spark eroded.
As for the hole in the water jacket if it's a cast block your have to cut a thread into it heli coil it and seal a grub screw into it! But best done with a tapered thread and if you do use a tapered thread you won't need a heli coil If the block is alloy see if some one can plug the hole

 

its on a mk1 focus rs, do you think its even possible to get through the easy out? i managed to get through the bolt fairly easily..

 

There's no way your drill into an easy out your have to have it and the bolt spark eroded

 

Use a masonry drill with a carbide tip
Grind it to the same shape as a std drill
First hole drill smaller than you need and work your way up
To size
Run the drill slow with some oil to stop it burning out
Try and tap the hole to a std size right through
Then put a grub screw in the hole with a shed load of ptfe
( if you helicoil you may have trouble sealing it )
But after you have fitted the grub screw you can helicoil the damaged hole
Ready for the new bolt

 

An easy out will be hard as hell cant see him drilling that out
