Crankcase pressure/volume build up

As per Rawzes blow by test video. As I increased my rpm slowly to 1500 the difference in the water level kept increasing and oil was coming out of the dipstick. I have checked for the usual blockage related stuff...crankcase filter..blow by drain tube..etc
What can cause continual building of crankcase pressure? I suspect the turbo but how would I test for that? I have not performed a compression test. Engine runs smooth. I performed a cylinder cut out test with Insite and it seemed okay. I'm at a loss!

maybe drill out the crank case filter so it can;t build pressure and hurt the turbo?
