Removing the PCV can cause oil consumption and leaks due to the crankcase pressure. We actually run vacuum pumps in our race engines to create a negative crankcase pressure which helps the rings seat and reduces oil leaks. Although in stock type configuration its lower but it still functions this way when plumed correctly. Even though it's considered an emissions control device they've been on engines before there was any emissions regulations for these reasons.
