Playin around with my spare engine im building today, and i see that there are 2 bolts broken off in the head. how do i go about extracting this?

 

easy outsthen drilling if it doesnt work...both with a torch. Which bolts are broken?

 

Get a tap kit from Sears:

i just picked up this engine from the previous owner, the heads are pretty new, just 2 bolts broken where the rocker arms would bolt to. can a machine shop do this for me?

 

more than likely they have taps there. call em to be sure.

 

sears sells an extractor that is reverse threaded and of a hardened alloy. It works great. You drill it in with the drill in reverse, then put the drill in forward and it screw the bolt right out.


Its a good thing to learn how to remove broken bolts yourself. Its a common problem and shade tree mechanics, will come across broken bolts. With the screw extractor you will not need to fix the threads in the block as it only damages the bolt and not the threads.

Its like $20, $10 if you go to Harbor freight, of course I think the crafstman quality is worth the extra ten.

 

awsome, i appreciate it.

 

Left handed (reverse) drill bits and screw extractors are the best way to start.
Soak down with penetrating fluid and let it sit before you start.
