Blow by question

I'll try and keep this short
first I've been having problems with oil leaking from the front and back of the intake so, I'm going to replace the gaskets this weekend and use only silicone for the front and back seal instead of the cork any thought???

second
I've noticed after running the car for awhile, oil builds up between the intake and head and it bubbles at ideal, if I remove the breather it stops Imediatly
could the pressure be so great that it's forcing oil out the front and back of the intake or is it dripping off the intake ???

any thoughts
