one of my stud on my B16a2 head broke. This stud is where the header is hook on to. How do i get the other half part out? does it effect the performance in any way? Can i drive with one missing nut? also, when i first put on the DC sports header, there was some white smoke coming out, now it stopped, but i was just wondering what it was. But yeah, mainly need help on taking out the other half of the stud so i can replace it. Any respond will help. thanks

 

any help?

 

My suggestion is to get a drill bit that fits into the hole and drill out as much of the old bolt as pissoble.

After that, hit it with some pb blaster and something like a dentist's pick.
