[AT] Hole in exhaust manifold....

[Al Jones]

If a manifold got to 2000 degrees, the pistons and associated parts of
the engine would be in the process of, or already turned into, molten
puddles.  Now it's been a while since I taught this stuff, but doesn't
braise melt around 800?

Exhaust manifolds can get hot enough to burn though cast iron why would 
anyone want to use something that can't stand heat above a few hundred 
degrees. I have personally seem some of mine red hot when run hard that
is 
over 2000 degrees.  Like I said before either braise it or replace it.
