[AT] Hole in exhaust manifold....

[Kevin]

I never had a heat gauge that would measure 2000 degrees, but I had a 68 
Dodge Super Bee that after changing camshaft in the 413 engine.  And having 
the exhaust valves duration changed so much that after a good run on warm 
engine, the ex manifolds would be glowing red hot. It almost looked like you 
could see through them. Even in bright daylight.

Now it's been a while since I taught this stuff, but doesn't
braise melt around 800?

If your exhaust manifold was made out of brase or brass yes they it would 
melt.
Since I dont have the measuring device or the car that done it, im out.
You can lead a horse to water     but can you make it drink ??
All anyone is doing is trying to say how each and everyone would fix thier 
own manifold if we all had holes in ours.
I have learned alot of ways to cure the problem and how others approach and 
repair thier stuff. Here I thought that I was the master of rigging oh well 
cant win em all. I still say the manifold is rotten burnt out junk and 
should be replaced.
But thats just the way I would fix it if it were mine. I hope the putty or 
wharever fixes it and it never gives more trouble.
Im out.
