Chain saw leaking oil bad

My chain saw was leaking the bar oil fast. It would be empty over night on the shelf. Oil was evry where. I found it leaking behind the chain underneath. The little silver ball was loose. I pushed it in until it poped in place. Don’t force it in if its already in the right spit you will clogg it up. It works fine now. It was out to far . I’m sure in to far is not good either.
