That said, I would never debate installing a component for safety sakes as each racer must decide for himself what if any component he needs to feel comfortable, above the sanctioning body's requirements for the type car and class they run.
All I know is that not one of my turbo400s built by a local builder as well Rossler over the past 20 years has ever puked despite cooking the fluid once or tiwce prior to using synthetic and all have been and are regularly hot lapped as well all retain the vent in the stock location.
