sounds like you might need to go down one carrier size on your level 10

If its coughing, I would say you are getting a bit of bolt stick. The leak is most likely caused by too many shims installed. Remove your powertube shims and use the largest carrier that doesn't leak. You may need to go to the next larger carrier from where you are now. Use the same powertube carrier oring for each check.
