alright so i just finished putting my new motor in my car with a 06 wrx tmic. and my BOV wont blow off...im not sure what the problem is when the bov came of my buddies wrx it worked fine now it doesn't open at all. the only thing i can think off that would cause this is maybe the vac line running to the BOV. im not sure where else i can put it becuase i have a 25D intake manifold. do any of yall have any ideas of where i can run the vac line?

The vacuum line needs to go to a manifold vacuum/pressure source. Where did you run it to?

Post a pic so we can see what we're looking at.
