I just got back from a four day vacation hoping to drink a beer I kegged last weekend. Problem is that it is flat and there was not pressure on to the keg. I have been having problems w/ a leak after i kegged the beer but I thought I got it taken care of. 
My question is that assuming the keg has had no pressure to it and has a leak and has been exposed to O2 for four days (worse case), is it any good?
Would going out tomorrow and getting the CO2 tank filled up again and hooking it up back to keg be worth it? Obviously, I'm going to get it filled but I would hate to waste more CO2 on a keg of beer that is ruined because of oxidation. Has anyone else experinced something like this? My keg setup was just fine untill after I hooked up this keg and I had to work on the lines a bit and obviously there is a leak where I thought there were none. thanks in advance.
