Hi @ all
1999 4x4 XLT
I've found on Passenger Side, the aft lower Exhaust Manifold Stud is Broken,
and there is a slightly Exhaust leak. (i hear it, because i know it)
The Stud is NOT Flush with the Head, but flush with the Flange.
Today i tried to drill them out, but no chance.
first of all, its nearly impossible to reach the Stud with a drill bit.
i've made it with the "Dremel" and a 90° gear, an a brand new 3mm HSS Drill.
I've only scratched and made a little tiny Crater.
but this Stud is such hard....
then i have tried a smaller one with carbide edges. (but not new)
And finally i tried to open the other Studs, to remove the Flange, no way,
The Flange looks pretty good but the Nuts and Studs are corroded.
I don't want to remove the Head, because, its hard and very expensive to get Parts here in Europe.
I've this at home:
also WD40, Caramba, Never Seize, and some other penetrating Oil.
I've also a TIG welder (but no way to reach the Stud)
and tiny Grinder (Drehmel)
should i try to grind a Slot in it, and heat it, and then try to get them out?
It drives me crazy to knowing a Leak (small leak) and no opportunity to repair.
Or is there anything that i could smear on it, some magic stuff?
JB-Weld ?! or so
