Ring Beer Bottle Opener

My homebrew keg leaked for two weeks and has no pressure. Is it still good and how to fix and recarbonate him?
So that makes my first batch of beer, what a girl 5. Weizenbier lot. I put 3 gal. in a small barrel and put the other 2-liter bottle cap. Used 1 / 2 cup sugar priming the whole batch and let it carbonate for 2 weeks. After exactly 2 weeks and left open a few bottles AWESOME. The flavor was good and clear without aftertastes strangers. In short, a great first attempt. But my 3 gal. barrel apparently had a leak at the top. Use a new O-ring kit, but had no a good lubricant for her and had to resort to cooking oil to a seal (fucking idea, I know). I also had no nickels to subdue plugs, so it had a leak. But is there any way to save? Do oxygenate during the flight? Did I hit him with a little CO2 and remove the lid, grease the joint with a better lubricant, use some nickels to give a tighter seal, and then hit him with the CO2 once more to press? It was so good and I was so happy and want some more. Please help!
I would say you know what to do. If you have rusty I can not say without a sample. Oxidation Classic is detected as a piece of paper / cardboard falvor. It is literally as simple as chewing on paper (but the beer taste can be very subtle) to get the flavor caused by oxidation of beer. A classic example of a beer commercial is oxidized New Castle Brown. Was there enough yeast to start a gentle ferment in the barrel carbonationg? Yes ****************************************** In ***** ********* NOT yeast form will produce methyl alcohol. There is a concern for you never when brewing. ************************************** ******************* I say, pushing him into a new barrel and either a new batch kraeusen or strength of CO2 in it with a stone corbonation beer. You can get a pressure gauge for you to test barrels. About $ 20-30 for a good suppler. Put it in your barrel and press. Take a few hours reading or days to track their ability to maintain pressure.
