We have had the same problem before.What we did was to run a Vac-U-Pan system,where the breathers are connected to the headers.This may not be the hot tip for a street car.On a street car,I'd run a PCV valve.

My guess is that you have either a pcv that is not working properly or the wrong kind of pcv or you have more blow by past the rings than you should. Have you done a leakdown test to caeck the ring seal?
