This sounds just like my story - the resulting leakage caused the thing to
run *really* hot - luckily I had my trusty head & oil temp gauges installed
so I could at least let it cool off before I ruined anything else. That was
a real slow trip. Going from CO to MD you at least have a tail wind, and
the weather is sure not going to be too warm, so you might make it.

My advice: figure out why its leaks - rings, valves or head sealing rings.
If you're lucky you can just flycut the heads, maybe lap the valves, and it
will be good as new.
