MG Midget and Sprite Technical - Crankcase pressure 1098 10Cg

I have a 1963 midget 1098 10CG engine. I have had it balanced, align bored setting the rear caps with a radial clearance of .004 and County .020 5 ring pistons (which I gapped to factory specs under a magnify glass). My problem is oil coming out of the vent tube on the front tappet cover. I have driven it about 200 miles hoping the rings need to seat and they are causing the crankcase to build pressure but the leak has not stopped yet. Anyone have any suggestions or Ideas?
