broken exhaust manifold stud

Magus, you should use some antiseize on those bolts. Even ARP will lose some hardness when cooked repeatedly. In my experience steel bolts just have a tendency to seize up with long term use in aluminum heads at exhaust locations. Antiseize works well there, what it was truly made for. I use it at all exhaust places like converter flanges, I've never broken a part it was used on.........

^^ thanks. Dont think i ever said at any time not to use anti-size on the ARP bolts. I have every type of anti-seize (normal. with copper, with ceramic, etc) so I have the right compound for the right job. You do have to realize though that when using anti-size it becomes a lubricated bolt so you need to adjust your torque when fastening.

I pretty much never actually torque exhausts anyway, no need. Never had a problem.

Not correcting you, just trying to help........................

Ceramic? That's a new one on me. I've got copper, aluminum, and nickel for high heat.

I like studs in aluminum, repeated pulling of steel bolts has a tendency to wallow out the aluminum.

The ceramic is for the brakes... so the label says....

:-) thanks for the heads up. every one needs a remainder every so often.
