Jay.
The blow-by issue is perfectly normal for a boosted engine.
Altho a remedy we use on high end boosted ones,might be an idea to ponder at least...
Check to see if you can increase crankcase ventilation area one way or another.

What we routinely do on the valvers is to open up the OEM fitting in the block for a mech pump just after the chain register as well as drill the OEM PCV fittings out as much as we can.

Point being that large area PCV outlets is a sort of mantra with boosted engines to me.
Stands to common reason that as dynamic compression ratio goes up....so does blowby.
If you opt to combat crankcase pressure iŽm sure youŽll notice a couple of things.
Oil consumption goes down,like in drops like a stone,and power goes up accordingly.

Just one of those small things that most people that boost their engines never get told about and that makes a difference.
