The higher the boost pressure the more force on the Valve so the chances of it leaking are minimal.When you back off the throttle, closed loop, you will instantly have a vacuum in the inlet manifold which will pull the Bov piston/valve backwards which will intern allow excess Boost to flow back into air filter side.Simple and very effective and having it return back into the inlet side make it a bit quieter than the aftermarket ones.I suppose the only real advantage of the aftermarket ones is the fact that regardless of throttle position all air must travel past the turbo and at no time can the engine run an N/A situation.. Possibly advantageous with maybe less lag????←Thanks F6, I learnt more in that post alone than in any other BOV discussion I've come across.
