Turbo Pcv ?? Mike norris setup on turbo application??

[66larkgs]

just put some miles on my 1966 Buick Skylark with a Nailhead and a t67 turbo with a blow thru setup. I am running into a problem with crankcase pressure. Car just started to smoke and push oil out if the valve cover gaskets. I have a valley pan underneath my intake that is already tapped for a 3/8 barb fitting and i was thinking of running a line from the valley pan to the filter air intake piping on the turbo. Hoping that would create a vacuum . Looking on running a line from the pcv on the valve cover and run it to manifold vacuum. I was looking into the mike Norris catch can but it has only 1/4 npt and wasn't sure if that will be big enough. any help or advice is appreciated. I have been reading for hours and I think this is the way I am supposed to go but want to make sure.
