Any horror stories out there?
PB Blaster is your friend!
I had to change out the cats on my '96 K1500 and some of the bolts were
really bad, I tried for awhile to get them off to no avail.. then broke out
the PB Blaster and socked them real good a few times, tapped on them, etc..
and finally got them all loose.
get out your torch if you're in a state where salt is used on the roads.
You should soak them, first with some good juice for a few days, repeatedly,
but I'd still keep the torch close by just in case that doesn't work. Heat
the flanges to red hot all around the stud - but not the stud, itself.
Then try to work it out by running out a bit, then back in, then back out,
etc. You may only get a turn or so before you have to reheat it again.
Don't get it too hot, or you'll be in a mess and don't get the manifold hot.
You are ONLY concerned about the flange.
Same deal with the nuts beforehand, too. Only get the nut red hot and keep
the heat on it, instead of on the stud, itself.
Work quickly when the heat is on, but pay close attention to what you're
doing under there because you don't want to fry anything you will need in
