Ok, whats the best way to get the 3 studs out of an exhaust manifold? Looks like they have been there since '72 and two are almost rusted (?) into or heat (?) damaged. :confused0006:

Heat them cherry red with a torch and turn them out with a visegrip ... when they start to cool reheat to cherry red. Don't turn if they lose color ... Joe

Mickey....When you put it back together, use the brass nuts....So they won't rust.

I use a couple of nuts backed into each other, soak it good with a rust buster and try that first, then to the heat and visegrips, but I heat the manifold not the stud. Heating the stud doesn't sound right. IMO

I wasn't so lucky when I worked on my 210 4-door Sedan back in the 1980s. I had to remove the manifolds and milled the remainder of the broken studs out.

(luckily my girlfriend at the time father owned his own machine shop that I used many times)

I'm with Rwhit, I would try something to break up the rust first. If you aren't in a hurry, shoot it with PB blaster for a couple of days, and let it seep in. I think you would be happy with the results.
