PCV exists for reasons other than just emissions, it keeps potentially corrosive vapors from collecting inside your crankcase.

Sam is absolutely correct that it will not hurt anything short term, but think about what is going on inside there over the course of a year or more. Water and gasoline sitting on parts that were never meant to have water and gasoline sitting on them.

I just really think it's foolish to do the "elimination" when you gain absolutely nothing by doing it and cause a vulnerability in the process. Last I'll say on it, I promise.
