It's not an oil slinger. That's been a myth that needs to have been busted for DECADES. It's an oil SHIELD to help keep oil directly OFF the front crank seal. That's its only purpose.

Why were the "oil shields" not installed on engines with the drip tray? Did the crank seal not need any protection if the drip tray was used?
