I believe that he's just using the K&N breathers on the fresh air inlet side of the PCV system and that would be on the valve covers front and back. On the 3.4 DOHC the intake sucks the Crank case blow-by from the front area of the oil distibution plate that bolts to the top of the block, under the lower intake.
