I found this in a previous thread "Crankcase Ventilation". The quote by Myron Piatek: {I wish I would have had time to sit down & find out how he did it, but Truman Fields showed me his set-up on his 400 Firebird many years ago. Not sure if it was the IHRA Pure Stock or regular Stocker. Anyway, he told me to remove the oil fill cap with the car running. After tugging on several times with no success, I figured it was a twist-on style. After many turns, that didn't work either. Finally I grabbed onto it and gave it a pretty hefty tug, and it came out! He had an amazing amount of vacuum built up in the crankcase.}

Question: Is the Valve Cover Breather a requirement?
