Yeah it would have to be pretty shrunken and rotted to let gas seep through without pressure, but that's not totally uncommon on rubber parts of that age. You could do a full leakdown test to confirm, but honestly this is probably enough of a sign that the bike needs a crank case rebuild and all rubber sealing parts should be suspect.
