I thought it was the gasket so I ordered a new one. While waiting for it to arrive I read some other forums where I read that sometimes the air vent on the front could be dirty and cause leaking. I popped out that vent cover and it was clogged. Using an old toothbrush and a tiny paint brush I cleaned all of the gunk out. No more leak even with the old gasket in place. I'll save the new gasket for when I need it in the future.
