   RW>  MH> lower intake themselves having what looked like "rotting" (like a

   The first time I had the problem with the antifreeze leaking on the lower   
   intake, I only had 66k on it.  It was just a few thousand miles out of   
   warranty.     
      
   After many conversations with GM, I was finally able to get them to cover all   
   but $300 of the repair work - which would have been $1500 at the time.     
      
   That same thing happened again at 146k miles, which led to me getting the   
   Jasper engine.  I had that problem plus oil was leaking around the oil pan and   
   a bit around the crankshaft.
