well mine wasn't sealing with three and now not with 5. I had the three in there on Joeys input.
ok I figured out where its leaking from. its not leaking from the intake but from the vacuum line to the intake manifold. if I remove the line the vacuum with stop. So I am going to try to get a thicker o-ring to see if that will help seal it better. if not I will have to get a different bov then I suppose.
