Do I need a breather setup...tunnel ram build....

Ok...I had my tunnel ram drilled/tapped in the rear for power brakes/timing/modulator valve...but I didn't account for the PCV as I was going to tie into the brake booster line. Well, I read this shouldn't be done, so now I just have breathers on each valve cover....

Are there any drawbacks to this other than maybe some mist on my covers or more frequent oil changes? My engine is a worn out 402 in a 72 El Camino...I am going to post my results in the near future about adding a t-ram to a stock motor.....

this is the "wiw" section. so, i'm guessing your set-up is worth maybe 40 bucks?
