The Bomb is ticking?

[Keith Lawyer]

I have a howling/grinding noise from my Bomb, or at
least that's what appears to be making the noise. 
Even w/my mechanic's stethescope I'm not 100% certain.
.. is this something the bomb is likely to do?  What's
worst case if it seizes?  Is the car driveable if I
remove the belt?  I've gotta go about 600 miles round
trip this weekend, but will not have the time to
change it between now and then.  Seems I'll have no
choice but to hope for the best. . .  currently the
noise is intermittent and noticeable only at idle.
