Kevin Dillon -- Cleared in Gas Station Assault ... Alleged by Teens

Just like Johnny Drama on "Entourage"... Kevin Dillon can now chant, "Victory!" -- after getting cleared in an assault investigation involving a mouthy pack of teenagers. 

Sources with direct knowledge of the case tell us the incident happened back in July outside a 76 station in Pacific Palisades ... when Kevin allegedly confronted a group of teenagers he felt was harassing and taunting him -- mostly because he's famous.

Our sources say the kids told cops one of them got into a shoving match with Dillon -- and the teenager fractured his ankle being pushed to the ground.

LAPD detectives investigated and reviewed security cam footage showing the scuffle -- but we're told it was unclear who pushed whom in the video. The City Attorney's office ended up rejecting the case in November ... due to insufficient evidence. 

We reached out to Dillon's rep for comment ... so far, no word back.
