i just installed my kit, right now the BOV is connected to the IM vacuum source.

well, all day the BOV was workin' and then all of a sudden it stopped, i can still kinda of hear it, but when i shift its more of a faint "whooosh" sound. rather than the "psshhhh" it use to make... what could the problem be?

i've checked all my IC piping and vacuums also....

 

Try adjusting the BOV bolt, it may be too tight. You can also try a different vacuum source from the intake manifold. Are you still getting the same boost pressure?
