Modern day emission regulations require the use of a closed PCV / Breather system to recirculate combustion blow-by gasses for cleaner operation and to reduce greenhouse gasses.
Due to inefficient capturing of oil particles within the air charge, a dense amount of oil vapor is allowed to be ingested within the intake tract causing deposits of carbon buildup at the intake ports, back of intake valves and oil deposits within the intake plumbing.
All will eventually lead to poor performance, reduced fuel economy and a decreasing octane rating.
