ok i was swapping cams in my b18a1 and when i went to tighten the bolts back down they snapped because the torque wrench i was using was unknowingly broken ok my question is how can i get these bolts out? they are the ones circled

 

1>Soak them with PB BLASTER penetrating oil
[Allow them to soak overnight or as long as possible]
2>Center punch with a quality automatic center punch
3>drill a small pilot hole in the center
4>Apply heat to the boss around the broken fastener
5> Use a low speed drill with left-handed drill bits
or you can also use broken bolt extractors but be careful..

If that sounds out of your range of capability,
I would suggest a reputable machine shop..

 

thanks for the help, i think im gonna try the broken bolt extractors cuz its sound much easier. but do you think they will be able to fit in the bolt hole?

 

why didn't you stop after the first one. maybe two, but three!! i suggest the machine shop idea.

 

Why wouldn't you stop after breaking on? Once one is broken you have to take it all apart to take the broken bolt out anyways.

ok well i thought the torque wrench was working, til i realized it broke a few. just a stupid mistake. im gonna try the bolt extractor idea though

 

Yes,thy make them in small to very small sizes.
PS>that bolt is a 6mm in size..

Also sometimes,
If the bolt is not "seized" or
"bottomed-out" in the hole,and will turn freely,

You can take a dental pick or a flatblade
screwdriver and just twist them out..

 

ok thanks for the help. i bought a bolt extractor kit so now im gonna try to get them out

 

try the easy out craftsman sells them you can get a smaller size us a drill center drill also and then us the easy out if it doesnt work get a 50$ b18b1 head get the newer style head...
