Many, many years ago, a helicopter I happened to be flying in took a round in the oil tank. We made it back all right, but we quickly received another call to pick up wounded personnel.
Our crew chief picked up a small piece of scrap lumber, whittled a point on it, and jammed it into the oil tank.
It wasn't pretty, but the people we picked up weren't too particular. As best I remember,we flew another couple hours before getting the tank replaced.
Onward and upward,
airforce
