You should send an e-mail to IAG to see what their suggestions are. They've been great at answering a few I've had in the past.
The best advice I can give is to expect blowby, not to try calculate it. Catch it using catch cans and don't give it a chance to make it back into the system. Almost every EJ or FA engine I've seen get built without a catch can comes back with issues and gets a catch can.
