   They're usually sealed pretty good. You may have another problem causing   
   them to blow out.

   With that kind of mileage, you're probably experiencing blow-by or a   
   plugged up crankcase venting system, causing the intake gasket to leak.

   Front or rear bearings?

   I ran Dexcool in my 98 Camrao (aluminum block and heads) up until last   
   year with no problems what-so-ever. Upon advice from my friend Harry, who   
   is the service manager at Benson Chevrolet in San Antonio, I switched it   
   to a generic coolant (green).

   Cleaning up an oily mess isn't much fun either.
