Crank case breather hose

[John Cassidy]

Listers!

I apologize in advance if this subject has been covered, but I cannot find
an answere in the archives.

Can anyone tell me the significance and implications of the crank cash
breather hose being colapsed?  I'm speaking of the big one that comes off
the back of the block.  Car is an '87 5ktqa.  Replacing it is no big deal,
and the car runs too good to be true as is, but what caused it?  Is
something about to explode?

Thanks,

John Cassidy
