I have 2011 outback 2.5 with 78,xxx miles .   Coolant was changed at 75,xxx miles and now my coolant outlet- under intake manifold is starting to leak, and needs coolant bypass pipe o-rings and intake manifold gaskets.    
  
1. How common is this?    
  
2. How much should this cost?  Dealer asked for arm AND LEG. 
  
3.  They said I can wait until it gets worse and keep adding antifreeze, but I’ve read this can cause engine damage. WHAT THE.... 
  
4.  I am disappointed in this car and the dealership for giving me bad information verbally, and different printed information.   
  
I have taken excellent care of this vehicle. It literally looks like new, and has been serviced regularly.    
  
Can I take it anywhere? Or should it go to a dealer only.    
  
TIA,
