i was putting my header back on today and one of the sutds just starting spinning while i was putting the nut on and now it wont tighten

will this definately leak or do you think i can get buy without it? Its the bottomw stud second one in from the drivers side

what is the typical procedure for fixing this?

 

jb weld y0

or the hole will have to be tapped again

or just leave it and you will probably be fine

 

Do it correctly. Take the mani off and remove the studd. Re tap it and your all set.

 

its easy to remove, u might as well do it right now.

 

you can probably use jb weld....

 

don't jb weld, you might not get the bolt back out after you put it in.

the holes for exhaust manifold studs/bolts have coils inside of them. your best bet is to call around performance shops, possibly machine shops although most machine shops won't touch your head without it being removed. there are 2 ways to repair this. one way is with helicoils (coil inserts) or timecerts (better, but should be your last resort).

in my case, i purchased 12.5 grade studs and just forced it in there, i had to replace more than one. i wouldn't recommend to replace any studs that are in good condition - you'll end up stripping more threads.

also, in future reference, try to use torque wrench, too much force or uneven pressure is probably the reason why you have stripped thread to begin with.

 

I found a longer stud (same size threads) at NAPA or somewhere. It fixed one of mine. Now I'm just careful about the torque on it (what is it, 25-30 ft-lbs?)

somewherea long that line, 23 i think.. (gotta check helms). i had one snap so this time 12.5 grade, i try to use 12.5 grade on as many exhaust parts as possible at least when they're small like that

 

i'm surprised that the helms doesn't provide a tightening sequence for the studs
