Exhaust leaks close to and broken flanges on the engine are causes to stop
driving. Cold air being able to rush back into the back of the exhaust valve
can cause the valve to warp. Gas vapors escaping during a hard or no start
followed by the flame front after starting can help start a fire. The heat
of combustion hitting stuff without being directed out the tailpipe can also
cause damage. Broken exhausts need to fixed.

And a question. I have had a very minor to major break in the exhaust for a
few thousand miles. The very minor was a lengthwise split about 2 inches
from
the head and extending for about an inch and a half. That was around in
somewhat patched to not patched for a couple cycles for about 5 thousand
miles.
The major was the driver side forward cylinder. Broke at the flange. Bad
mojo. 20 miles home.
Patched with the nasty white exhaust paste wrapped with the high temp buck a
foot exhaust wrap and then with steel fence wire with about 1/16 to 1/8
spacing.
Lasted for 150 miles, almost all I needed last summer.
So the question - is proper/even back pressure a critical thing on these
engines? Because this thing is more balanced cylinderwise and just in
general
than I remember.
