If you have excessive blow by, make sure the lines marked in red and green are hooked up correctly and not blocked.  Pay special attention to the orifice fitting in the valve cover.  If it becomes clogged with carbon deposits, the CCV (crankcase ventilation) otherwise known as PCV (positive crankcase ventilation) won't work.
