Help needed please: cant get max boost after timing belt change

[EKellock@aol.com]

Well I checked all the hoses and didn't find anything that looked bad.  I
pulled the oil filler cap and the car stalled.  That's the way it should be
right?  I also checked to make sure there is no slack in the throttle cable.
 
I did find a hose that is collapsed.  It's a wide hose with tapered ends that
connects to the block on the lower end and to other hoses which are connected
to the valve cover on the top side toward the back of the engine.  It looks
like a crankcase vent hose or something.  

Any other ideas?
