Would you guys have done this? I have a car with a maniverter setup, the catalytic converter is the exhaust manifold and it's attached to the engine using two nuts and two bolts. The two bolts that thread through the cat and engine, tap into the engine as blind holes.
Now these get really hot, hot enough that I can smell anti-seize burning even though it's rated for 1000+ degrees F.
I'm wondering whether I made the right choice applying anti-seize to the bolts that went into the blind holes. If the anti-seize is burning is it expanding gases that can't find their way out of the threads and will end up popping something? I keep hearing about grease hydrolocking threads off of bolts, if it's burning the gas could compress I guess, but where does it go? And is it going to fatigue something? Sorry I'm really stupid about these things. I don't know what the industry practice is for AS on a blind hole at high temp.
Would it go past the exhaust manifold gasket instead since that's right between the two pieces the bolts are clamping together? The bolts did have a little thread corrosion so maybe they're not air tight when threaded down at a microscopic level and offgassing can still makes it way out if corrosion can make its way in?
