how much oil does the coupler need? on 1993 Pontiac Bonneville

knocking sound when engine is running. Replaced bearing,and put a 4 oz bottle of supercharged oil, but the knocking sound continued. How much oil is supposed to be put in there?

I think you fill until the oil is at the bottom of the fill hole. But check your manual just in case. A knock sounds like more of an engine lower end problem than a super charger.
