Oil Separator?

Hey guys, hoping you can help me out. I installed an oil seperator earlier this summer. i lose oil and from doing some research on the site i was hoping the oil separator would help catch some. like i said, it has been in since about june and there's about 2 drops of oil in it. i am confused. i figured since i was losing oil it would be caught in this separator. i blow a little smoke at wot so i was hoping this would help until i rebuild it. why is my oil not collecting in the separator. i have the in side going in to the pcv valve and out routed to the t fitting under intake. i also have a new pcv valve, grommet and screen. i don't really have any mods except roller rockers and underdrive pullies the owner before me put on.

can some one please shed some light on why the the seperator is not collecting oil. i am probably just not understanding something.

thanks for all the help
