just my $.02 but on engines i have built, people wailed on them to hard to soon. as in before the rings were properly seated or "broke in", causing excess blow by. i saw you said it was a fresh rebuild. how many miles have been put on the fresh motor, and how hard? was this the first time you took it over 5000 rpms? it may need more time to seat the rings. i usually run one vent on the right valve cover, usually the right. on older motors that didnt have pcv, i put the pcv on the left. (what ever is easier access to the air filter, as you want CLEAN air going into the motor)just sounds to me like you are having to much blow by. it is not usually unburnt fuel/air mixture as i have found. but pressure from the combustion, and the rings not sealing properly. old wore out engines, or new ones not yet broke in, and the pressure is easier to go around the rings rather than push the piston. but on ocasion, you can get unburnt fuel into the crank case. thats bad juju. check you pcv valve for proper operation, and make sure you have adequet fresh airentering the crank case. just my 'speriences.
