This is my experience. Twice :) Maybe it has worked for others, but not me
(2X) No way.
JB weld will hold (or plug) a manifold leak for about 6hrs run time max.
You can use it in an emergency, but the heat of an exhaust manifold will
turn it to a pretty white dust that will easily blow away after 6hrs or so.
Maybe an intake, but definitely not an exhaust. Find somebody to weld it
(heat it up glowing red with your torch and use a low hydrogen rod (or
nickel) If someone has used JB on a exhaust manifold successfully, I
curious on the particulars.
