440 w/TorqStorm SC - Boost Getting Into Crankcase?? Valley Pan BULGE

The LS engine guys running turbos all usually use crank case vents plumbed to puke tanks on their racing engines. I think it is pretty common to have some positive pressure in the crank case when hammering on a boosted engine. Those guys have a lot of aftermarket support made for dealing with this kind of application - maybe poke around on their forums to see if you can pick up some info.
