allright i know i am going to get bashed for over tightening here but heres it goes i recently purchased a set of some aftermarket tall valve covers. the other day i was installing the passenger side back on the car and DONT ASK ME HOW BUT I OVERTIGHTENED now the bolt broke in the ALUM HEAD and there isnt even enough material for me to grab with any type of grips.

2 things that i do know the hole doesnt go through to the bottom of the head it just dead ends there in the hole i also know that its a 1/4" bolt that goes in there.
i will be able to drill it out cause it wasnt one of the rear ones so that wont be a problem . but i how will i tap it out do they even make a small tap that will back that bolt off and out. i know for sure i didnt crossthread it all i did was overtighten so it should come loose easily with the tap.

does anyone have any ideas on this. part of the reason these valve covers did this to me is because they dont have a reinforcement coming from the top of the bolt hole entrance all the way down to where it screws into the head like the factory BLACK VALVE COVERS.

arrrghhhh.....i need patience,,

thanks z28 trick

i have to see where i come up on of those should i get it the same size as bolt or smaller do they make left handed thread bits 1/4" or smaller...

Use an easy-out. Just go to the store and get one for that size bolt.

if you get a left handed drill bit get one that is a little smaller than the bolt.. they are a little cheaper than extractors i think but those are good too
