Almost without a doubt, you have a bad head gasket.  You will need to pull
the head, and replace the head gasket.

> We were traveling from VA to NY on friday and about three hours from our
destination one of the large radiator hoses popped off the plastic pipe
underneath. We stopped immediately and put the hose back on by the side of
the road and filled up the system with tap water from our sink.  We then
drove along (temp normal) for about two more hours and stopped for gas and
dinner, topped up the expansion tank, everything seemed fine.  I noticed
that the exhaust seemed quite steamy when we got going again but it soon
looked normal again.

> less than a mile from our destination the hose that connects the driver's
side head to the plastis pipe over the expansion tank burst and we stopped
immediately.  We let it cool down for a few minutes, refilled with water,
and drove the last 2-3 min with the temp gage reading just above the LED.
As soon as we stopped, I jumped out and check the engine and it didn't seem
hotter than normal.

> This morning, I replaced the burst hose and filled and bled the system and
after a few minutes of running the exhaust became very steamy and smelled
like coolent.  After a few more minutes, the engine started running rough.

Buffalo, NY.
