When does the 1G BOV start to leak?

[TalonFiero]

My 1g bov leaked at idle. After I setup my GM MAF and MAFT in blow-through configuration, I vented the 1g blow off valve. It would suck air in at idle sometimes and it got really annoying. I bought it from a friend who purchased it brand new so it wasn't worn out, just doesn't like to be vented.
