Header bolt missing?!?!
 

Just a few days ago my header started making a familier sound.... every once in a while i have to tighten my header bolts (every couple months) and i went in there to tighten one and WAMMOOO! it was gone, i mean the stud and the nut had backed out of the block and was completely missing.... Oh man its not a nice sound. has anyone had this happen? What tool do you use to get another back in there... i hope it hasnt sheared off... i cant see yet!?!

I believe the nuts are lock nuts. Try double nutting them next time if you don't have the locking nuts.

Had the stud closest to the firewall break off below head level a couple of years ago. Took a weekend to get it out. Poke something in the hole to see if it is broken off. The studs go into the block about an inch.

If it is sheared off you'll have to remove the manifold to get at it.
