Are you sure that you definitely have a pressurized crankcase? If you do,
you will hear & feel a 'whoosh' of pressure when you open the oil filler
cap after a bit of running.

Even a new engine has some amount of blow-by - it's the amount that makes
the difference between a new engine and a tired one. Anyway, even if you
do have a lot of blow-by, I don't think that's your problem here. Your
engine should be able to vent the pressure - check out the PCV hose, valve,
and especially where the hose connects to the intake manifold. A
restriction here would be the likely cause of a pressurized crankcase.

Hmmmmm... Just where does the PCV hose get connected when you do a Weber
conversion?
