Well the new header was loose, no problem just tighten back up...except one of the bolts is missing.

So....what is the tq spec and why did one vibrate completely out?
I don't know the torque spec ... but if in doubt tighten it up where you had it on the install ... but this time USE LOC TITE! It will stay put.
